Should You Bi-Amp Your AV Receiver? 

1:04 I can’t bi-amp, but I watched the whole video anyway. Take that!

I'm currently bi - amping a pair of Mission MX3s, using a Marantz SR5007 receiver in stereo mode. Sound is so much better than when i just used the main speaker outputs - fuller and tighter bass, richer midrange and more defined treble. Also, soundstage and imaging have improved. I'm more than happy with the sound, and i don't think that i will go back to the old way.

I bought the Denon 3600H last year. Since it has 9 channels of amplification I’m running it bi-amped on my klipsch towers. My set up is basically 5.1 with height speakers in the front. I love streaming music to listen to in stereo. Bi-amping definitely improved the clarity of the highs. It actually improved the imaging too. I went back-and-forth a few times and it definitely seemed like something was missing when I wasn’t doing it. It’s tough to judge comments from people since you don’t know a persons given level of competence and understanding when addressing technical issues. I’m not saying I’m an expert but audio is a hobby of mine and I think this receiver makes enough of a difference when listening to music to be worthwhile.

This hurt my heart. Have a tsr-700 that I'm currently using 2 channel with b&w 606s2 and got excited when I saw I could bi-amp. Thanks for crushing my soul.

Hi gene, I am using an integra home theater receiver and I am using the bi amp feature with paradigm speakers, and to me they sound clearer and more spacious whether it’s all in my head because that’s what I’m supposed to hear that remains to be seen but I’m happy with it

Running a Marantz SR8012 and biamping the two front speakers, old Paradigm Monitor series, using the preamp mode and two Rotel rb960 BX amplifiers. Old stuff but sounds really nice. Lots of power.

I have no idea if this will ever be read but I recently reorganized my setup. Running a PC as my main media source. HDMI to TV for 4k on 65" HDTV, and a second HDMI cable to my old Onkyo TX-SR605 5.1 Receiver. I've had it for over a decade and I've never had a single issue with it. I run two Energy Connoisseur CF-30 towers (more on those in a minute), an EW-100 subwoofer, and Energy centre channel. I started with the 5.1 Take Classic set and have upgraded over time. I'm not currently using rears or the surround. That gave me an interesting opportunity however to use the surround outputs as bi-amps for the tower speakers. There is a label on the rear outputs, and a setting within the receiver setup menu itself to enable the feature. I've been running that for a while and it seems to perform well. However to my ear, it sounds almost the same as a passive bi-wire setup to the same speakers. There IS a noticeable difference to having it bi-wire/bi-amped vs not at all so I will continue to run it bi-amped until I upgrade the whole system. Just fyi previously I was using TOSlink optical to run from the motherboard to the receiver, but had my eyes opened when I was reminded it only provides 2 channel PCM rather than the higher bandwidth HDMI. Thanks.

I have a denon 3808, it’s a 7.1 system with a 2ch assignable which can be assigned for bi-amp or a separate zone or even a separate 2ch system and even incorporate it a 9ch system which is what I’m using to power 2 small bookshelves I have NHT-VT2 LR speakers which has passive subs at the bottom which is powered from my avr and the subs are bi-amped with an NHT-SA2 subwoofer giving me that extra base

Bi-amping Polk monitors with budget Onkyo AV receiver, definitely makes a difference.

I use the bi-amp feature to run 4 front floor speakers. It’s a 7.2 channel Yamaha and all the channels output the same watt. Changing the setting to bi-amp makes the receiver a 5.1 channel. But instead of running one channel to the upper of the duel post speakers I just power one set of speakers with one channel and another set of speakers with the other. Sounds great running it In 2.2. Channel.

100% agreed, but when cheap receiver came to the equation, really smear the real benefits of biamping. in my years of testing definitely you will get benefits, but you must be aware that using external amp / preamp processor is the way to go. Better dynamics, solid bass response, more high details, (not to be confuse with more power)i must agree that to be able to feel a huge difference you must gain over 50% of the volume. Cheers.

Hey Gene 😀 First of all, a very big Thank You for the great knowledge you put into this. I have watched a few of your videos by now and I must say you do a pretty good job 👍 My setup: Marantz SR4003 drives the mid and high on my Yamaha NS-777 front speakers. I used the front pre-outs for my ROTEL BX956AX power amp in bridge mode, that drives the front woofers. Subwoofer: Rockford Fosgate Punch III 10" 400w rms, peak 800w driven by ROTEL RB-980BX bridged to 1 * 360w rms 8 ohm. Good day to everyone 🤗

Yamaha DSP-A1 :) Rock solid Integrated Amp

I bi-amped with my Denon x4000 AVR with Monitor audio RS1 bookshelf speakers. The speaker are 6 ohm rated by the manufacture. The crossover setting was at 80Hz. My AVR amp was fried. Several resistors were burned out on rear channels according to my local electronical repair man. It cost me $185 to repair.

Can you make a video on the placement of in-wall/ceiling mounted speaker and what you recommend at different price points?

I bi-amped my RP-600Miis with my Denon AVR-X4700H to go along with my other 5 speakers and sub. Personally, I heard a difference when I realized the receiver had the bi-amp feature vs single-amping and tried it out. It uses 2 of the 4 height channels, neither of which I use, so I figured "what the heck." Like you said, it's a bigger effect when I'm only using the /R speakers listening to a CD, a vinyl album or streaming music.

Thanks for the impartial information. I passive bi-amp Martin Logan Vistas (electrostatic) with the Onkyo TX RZ50. I listen mostly to 2 channel music (plus sub). The MLs sound great! and perform well as fronts for a 5.1 system. The RZ50 has 120W/Channel at 8 Ohms. Seams to be enough power to drive all of the speakers.

I have played with it over the years. Both with car audio and home audio. I think there are two scenarios where bi amping can work. One is if you have very power hungry speakers and you drive them with separate amps. Two is if you are using active cross overs. I even went to the point where I built this complex set up with custom built speakers and drove each driver with a different car audio amp and active cross over. I used a very large custom sub woofer that played below 20 hertz. Then either 8 or 6.5 inch woofers, I don't remember which size I used each in their own custom tuned enclosure. Then another enclosure with the mid range and tweeters. It worked extremely well but I don't think it had that much to do with the amplifier power or that it was using multiple amps. I think it had more to do with the fact that each driver had an enclosure tuned to it and that I spent a lot of time matching levels and adjusting the cross over. I think if I was capable of designing, testing and building a really high quality passive cross over it would work just as well. And designing a decent cabinet to house all three drivers and work well isn't rocket science either. And then just use a powered sub woofer with a good built in cross over or an outboard one. When you boil it down using a modern powered sub woofer is really just bi amping your system. You are basically just using a different amp for low frequencies and using an active system to balance it out with your main speakers. I have an older techniques that has bi amp, I don't remember the model number off hand. It was from maybe 1999 or 2000? Back when you had to use the outboard 5.1 decoder to go with it. And it weighs a ton compared to newer stuff. I tried bi amping it and it didn't make much of a difference to me. At least not when you are just hooking it up to normal towers with a built in average quality cross over. Its by far the best amp I have owned in terms of sound and build quality. I just outgrew it in features and what I needed for inputs. It doesn't have any hdmi switching or any of that. I am keeping it for when I have the room, time and money for a dedicated two channel system. Right now I use it to power a home made sub woofer since it has a built in sub amp in it.

If your receiver and speakers have bi-amp capability and you can spare the back surround channels, then I don't see why you wouldn't. Maybe you don't want to spring for another set of speaker cables? Maybe you don't want to wade too deep into the receiver's settings? I treated myself to a pair of Paradigm Premier 800F's recently and was all too excited to utilize the bi-amp feature of my Sony 3400ES. It is massively important to ensure that matched amplifiers are used for bi-amping, no mix-and-match. Also, make sure your speaker cables are the exact same length. I think on paper bi-amping allows cleaner power to be delivered to the mid and tweeter and may confer some additional benefits when considering impedance stability. The bass section of the 800F's is relatively solid but I definitely didn't bi-amp to realize bass gains as I bought a pair of Paradigm Defiance X12's to round out the 800F's bottom end. It may be useful to note that even though the receiver has lots of theater chops, I'm using it in a 2-channel setup. A small subset of gear owners actually bi-amps but an even smaller subset has the gear to utilize active bi-amplification. My speakers offer no way to defeat the internal crossover network and I'm okay with that because I trust Paradigm gave those 800F's the best crossover for what they are capable of. As to bi-wiring - you're just wasting speaker cable at that point. If you really want to buy another pair of speaker cables to do this, remember: "a fool and his money are soon parted". Speaking of, I will probably go back to not bi-amping when I spring for that Anthem STR amp as it is already breaking the bank just to have two channels of that sweet "Crafted in Canada" sound. But that will be mostly offset when I eventually pair it with an STR pre-amp and join them with XLR connections.

Bi-amping for 2 channel listening only. Both older components: Pioneer Elite receiver rated at 140wpc to Yamaha towers. Noticeable extra headroom as Gene says.

Gene, I have the Denon AVR X8500HA with an external Monolith 5×200 watt power amp that I'm using to Bi-Amp my front SVS Ultra Towers and also use it for the center channel. I use the Denon to power the other 6 + 6 channels... it's a beast in this configuration and I love it!!!

I say try it. I have a Denon 3802 from 2002 and I have re-purposed it to my office with a set of Elac Uni-fi UB5's and a couple of 10" Klipsch subs I picked up off of CL. I run the UB5's from 80hz up with the internal Denon HP filter, and take the L/R line level out to the subs and use their LP filter. So now I have a kick-ass 2.2 system for very little money. In the theater room I have a Yamaha 850 that is bi-amping my Tannoy Saturn 8's and it is a noticeable improvement at higher volumes. Again, try it and if it is not an improvement, it's easy enough to go back.

I have a DENON AVC-3800 from 1996, and this amplifier has Left Center Right in BI-Amp and still is very powerfull

Very helpful Gene! Thank you. I received support on this topic through the Website recently, Peng and others. I Bi-amped my high end top of the line Sony AVR to the mid and tweeter and My Anthem amp PVA4 to the bottom drivers of my Paradigm 95fs. I used the SPL meter and found my ear was .5 db off on my front right and surround left all other speakers except subs, were spot on same level. I used your SPL video to help me understand how to do that. Thanks again! My subs were much lower on the SPL meter. Way off there. I turned both subs up to same DB and have really felt I'm enjoying Atmos movies the way they should be along with my 2 channel music at the best it can sound. Many of us have limitations on speaker placement due to room size limitations to fit furniture, TV, audio equipment etc.. Practically no options. I appreciate the advice on the room correction. I just do the distance and level by ear instead with 80 crossover and small setting. As per above I was almost spot on to the SPL meter. Two channels left on my PVA 4 so I used 1 of those also combined with the Sony to bi-amp my Center channel cc590 which now also sounds clearer and more pronounced at low and high volumes. Another big advantage. I plan to study Peng's advice to compare the single amp hook up vs bi-amp just for fun and because I can't stop messing with everything. I am also now a subscriber!

I stopped using receivers after it seems they all eventually break. I have gone to an extremely strange home theater system. I am using car amplifiers, DC power supplies to run the amplifiers. I swear these amps have so much headroom it's unreal. I will probably never go back to a standard receiver. Also, I use FLAC audio for music listening. My home system is very, detailed, revealing, and not to mention very loud and clear.

Easily the best, most informative clip i have seen regarding this topic. Makes absolute sense of a grey area in audio. Thank you

The Cinema 30 i was testing can biamp but sadly i cannot bi-amp the center alone. I have SVS Ultra Bookshelfs in the front and the SVS Ultra Center. The Bookshelfs are only rated 150Watts but the center is rated up to 225Watt. Thats where i would want to use the biamp because that speaker potentially can do something with the added power. Its a 3 way so i guess mid high and bass are separated. That might free up some additional room in difficult movie scenes. Its not a issue but it would have been nice to be able to select the Center only instead of biamping the two fronts. Its either the Front two speakers o 5.1. And with the A1H its the same but for 7.1 The custom mode wont let you set what speakers you would like to biamp. It would have been nice to have more flexibility with setting where you want to allocate the unused channels.

I have a Marantz SR6014 and have noticed a benefit of bi-amping from the AVR. I also have a Parasound 855A 85WX5, I noticed a bump in power with this as well. Using Parasound for bi-amped towers and cnter and running surrounds off the AVR.

Another interesting video Gene - thanks. I have a request for a topic I haven't seen covered anywhere: Why are there no $1000 pre-amp/processors? Why does a pre-amp - that has no amplifiers - cost more than the same company's flagship receiver even though it has the same processing?! If ever there was something that feels like snake oil, this has been it for me. It's like an audiophile luxury tax. How on earth do companies like Emotiva - who otherwise sell great stuff at reasonable prices - think they need $4k for their processor?! If Marantz/Denon have actually put in a feature in their receivers to TURN OFF the amps, effectively turning the receiver into a processor - why isn't there a cheaper model with no amps? And the worst part of all this is that it is the processor that becomes obsolete, so that's the piece that I want to spend the least on because you're going to want to upgrade it eventually. This has bothered me for 25 years. Would LOVE to hear your take on it.

I find it very interesting that you came up with Bi-amp for Denon , Marantz & the rest of the market to follow. Thank you for sharing! Personally I perched a 2nd hand set of B&W dm603s3 floor speaker and paired it with a Yamaha rx-a710 7.2 channel. Not good so I saved for a Onkyo 9.2 channel bi-amped them and crossed at thx80hz with HSU research subs do most of the work.

Perfectly said. I use an old Pioneer VSX-AX10 to bi-amp my speakers. But I do it externally by splitting the incoming signal with rca splitters and feeding the signal to the multi-channel analog input.

I built my own bi-amping amp, 4 lm1875 ic driven mono blocks, 2 active analog 2nd order active cross over with an output protection circuit…oh yeah large toroidal xformer, nice bunch of caps… so yeah. Sonically impressed ,I had chosen speakers before deciding on cross over frequency point ….. I need to get it fixed up, one of the amps inside shorted out when I tested it after 10yrs of storage. Maybe I can put in some class d amps and revamp the whole thing. Would be a great project AGAIN.

I've bi-amped my Bronze 100s. I really just did it for two channel cranking it really loud for music. (I play music louder than movies 😂) I don't think it's making a big difference. But I haven't heard any negatives listening either so I'll just leave it be.

I'm using a marantz 6013 as a processor. My amp is the jbl synthesis s7150. I tried bi amping using this feature. Didn't notice ANY difference whatsoever. My rp8000f are already very efficient so I don't think I was getting anywhere near to utilizing all that power. Only thing I ran from avr was my 2 height channels.

I have Arcam AVR20 and positive difference with Bi-Amping is clear (KEF R3)

My system consists of a Pioneer VSX-1023 ($500 avr) and a couple of Altec Valencia speakers/cabinets. I removed the crossover networks aqnd installed banana plug jacks to use in bi-amping. The avr has a bi-amp feature, but there are a couple of issues. The crossover frequency was designed at 800Hz. and the avr has a 200Hz. limit. The other issue is the lack of clarity about using the feature. The manual states the bi-amp feature includes Surround 5.1. I've done the bi-amp section but haven't figured out how to get the Surround 5.1 in the settrings. My test file is the TV episode: Star Trek s01e04, with 3F2MLFE audio configurtion. Thanks for the video, thanks for the information.

After your old video on the subject I bi amped my Denon 4400 and B&W 683s2 setup for 2 channel listening. Worked great for years now. Used Blue jeans cables also:-)

I'm looking to get a new receiver & going 7.2.2 not bothered about Atmos.

The 805 d3 is a very respectable bookshelf. I passive bi amped them on an Yamaha a780 running a 4.2 configuration I saw benefits

Hi folks, I currently use an old and cheap denon 1912 in bi-amp mode on the fronts, wich are floorstanding canton ventos 890.2, wich are capable of a power consumption ups 350 watts. Trust me, it does make a difference in stereo to a certain point at higher volumes, where it has a little more breath than Single amped. But the small powersupply has of course it’s limits built in. I ordered a denon avr x6700h as an upgrade and will probably use bi-amping again, since I drive a 5.1 system. I‘m curious what the higher class amp and the bigger powersupply can do.

Only Sith Lords deal in absolutes... ~Gene 2021

Dang, I have those same Paradigm speakers Gene showed in the video! (Premier 800f’s) and I’m using them with a Marantz SR7012 in just a 5.2 setup. Maybe I should do this whole Bi-amp thing! 🤔

I’m happy to hear some bi-amp discussion. I’m shopping for a new receiver and the ability to bi-amp it a must to drive my Polk towers. I’d appreciate some help with choosing my next receiver. Basically running 5.2 now and I want to add atmos. I’m thinking I need at least a 9.2 to bi-amp and then end up with 7.2

Seems u needto consider the source of the signal. Is it a true biamp situation. Is the signal coming from a separate amplifier within the receiver? It's not a big deal to do it if your receiver allows for it.

What about the definitive SM55 bookshelf? I have a Sony 790 receiver, should I Biamp?

I have a Yamaha RX-A3050 and I was running Paradigm Studio v.3 100s, CC470, 20s for the back, and can't remember the model # for the sides. Plus a Servo 15a. Bought them all new. About 12 years ago I picked up an Onkyo TX-S876. Nice amp for back then. I needed an upgrade and wanted something for Atmos, so I picked up the Yamaha a few years ago, and took a pair of cheaper Cambridge Audio small speakers I had to mount on the ceiling for Atmos. For a long time I was thinking about using the Onkyo for bi-amping the 7 Paradigms, but a lot of people in the Facebook groups said I should just get external amps. Or at least an external amp for the front 2 or 3. I'm on permanent disability, so money is a lot tighter than what it used to be. I knew that A/V receivers generally rate their power in 2 channel mode, so I started thinking of using the Onkyo to just power the front two, and then that would give me 4 ceiling speakers for Atmos. It turns out, the Onkyo TX-S876 also supports Bridged-mode. Close to doubling the power for the fronts, especially if it is only powering 2 speakers. I bought two sets of Paradigm Cinema 3.0 speakers, using 4 of them for the ceiling, hooked up the Onkyo in Bridged mode, and now running 7.1.4, all Paradigm, and definitely have a noticeable 'punch' in the front speakers now. I also just picked up a pair of 10G BlueJeansCables for my fronts after watching your vid about cables. I've always believed that cables don't make a difference, like most. I had/have 12G, pretty decent speaker wire that I put Banana plugs on the ends and always thought it sounded good. I hooked up the BlueJeansCables, and got ready for a serving of humble pie. Dire Straits, "Money for Nothing" in high res, such clarity. But it was Donna Summer, "I Feel Love", only took 3 seconds in for my jaw to drop. Expensive speaker cables, as you pointed out, not really worth it. But actual speaker cables to power your fronts when you have a decent system, then yea, it's worth it. . Video idea/request. Decoupling speakers from the floor. What are good options? Sound dampening foam, spikes, rubber spikes? Do those expensive ones make a difference over the cheap ones? IsoAccoustics are hundreds of dollars on Amazon, and then there are spikes+disks for $20.

I have the pioneer sc lx801. The bi-amp feature was noticable with my klipsch rp280f speakers at higher volumes. Better bass response and cleaner highs. Though l did buy a 7 channel power amp and no longer need to bi-amp as the amp puts out more than enough power per channel

Hi Gene I found the video informative, I have a Denon AVR X4300H Bi wired to Montitor Audio silver RS8. I did this thinking that the speakers would sound better driven Bi wired at lower volumes as you have two amps driving each speaker. I have done this from the start on getting the Denon and have been happy so far. Tell me is my thinking flawed or is it wishfull thinking.

I got some speakers that are bi amp capable, now I want to use it, my question is do big recievers split the highs and lows when set to bi amp, or do they send the full signal? I can't decide if I should get a better receiver, 2 amps, or one more powerful amp. Thanks to anybody who can answer this for me.

I haven't bi-amp'd anything, but when I originally built my media room, I bi-wire roughed in all the surrounds. Didn't make a damn bit of difference. But it did pay off when I went to an Atmos setup because I had all those wires running through the ceiling chase. Win for me.

Do you think this would be worth while on a Marantz 5015? I just ordered a pair of Martin Logan Motion 40i fronts. I'm only using five channels and it has instructions for just this scenario. "This system plays back 5.1-channels. You can use the bi-amp connection for front speakers. Bi-amp connection is a method to connect separate amplifiers to the tweeter terminal and woofer terminal of a speaker that supports bi-amplification. This connection enables back EMF (power returned without being output) from the woofer to flow into the tweeter without affecting the sound quality, producing a higher sound quality."

Using a Sony 7.2 channel AVR in a 3.1 speaker configuration. I bi-amp the front speakers thereby using 5 of the available 7 amplifier channels. No noticeable sound difference at normal listening levels. Ignoring power supply limitations, each amplifier channel is operating at one-half of the power load compared to a standard speaker connection.

When the Receiver's power is split between the number of channels one uses, i.e. offering more power per channel when less than the total available channels are in use, in that case I'd guess that bi-amping would be useless. Am I right?

I bi-amp my Martin Logan towers, with two Parasound stereo amplifiers. I love their performance via this configuration. Personally, I left AV receivers behind many years ago. I only use separates because I prefer that approach.

Biamping fronts on marantz sr7010 but does anyone know how I can Biamp the Centre speaker??

I’m bi-Amping from a Denon AVR-X3700H to Monitor Audio’s gold speakers 100’s into 4 Ohms, using a Monitor Audio subwoofer. The speakers are classified as bookshelf, not set up as advised as I have to compromise in my home area. The sound is superb in my opinion using my hifi components.From experience you will never completely be satisfy with your sound, because music quality recordings are so inconsistent. While I’m interested in improving my sound I will try all sorts of tweets.

i have two unused channels on the amp & the feature for it, so i bi-amped my 2-way speakers and i love it. i am used to my system for years now and to get this extra boost of power to the system with only two additional cables is very welcome and totaly worth it. but i was disapointed that the audyssey does not mesure the low- and high channels seperately. i think the bi-amping feature would benefit a lot and be more worth to try for more people. i tried now to mesure the low- and the high speaker seperately and afterwords i changed the distance and the level to the average worth. the result is pretty good i think. do you think thats a good idea, or do you see another solution to mesure the channels seperate but in one round? sry bad english :D

I have a Sr7009 and I have 5.1+bi amp in one room for home theater, and two channels in the bedroom as a bonus. I could then skip the stereo amp in the bedroom, as well as benifit from the better dac in the marantz. (had line out from the nuc pc before)

I own a Marantz SR 7013 and Paradigm Premier 800F coupled with Paradigm Premier Center 600C and the main surrounds are taken care by NHT SuperZero 2.1's I'm running only 5 ch and I use a pair of SVS PB-1000s for the LFE's and main channel crossed at 80 Hz. I had bi-amped in the begining and was listening to music strictly on pure direct mode and felt it was slightly beneficial to biamp. When I integrated the subwoofers, I couldnt find the biamping the 800F + 7013 was beneficial... 800F's are fantastic speakers for money and thanks to audioholics for reccomending it.

I Bi-Amp my L+R but I don’t bother with any of the Receivers Amps even though have a nice Denon, I have a 5ch Amp that I send 400+/-wRMS@4Ohms to the L and R and use the other for my C until I can get my 2 MonoBlocks then I’ll be able to send 1100wRMS@4Ohms to my L+R and then I’ll Bi-Amp my C and send the other 3ch to my rear Speakers or depending when I get the MonoBlocks if I upgrade by then perhaps I’ll use it for front height Speakers for an Atmos System.

Hello, bi-amping from my Denon AVR-A110 to my Klipsch RF-62 II's. Running a 5.1.4 speaker setup.

LOVED THE VIDEO, WHAT ABOUT USING THE PREOUTS TO A SEPARATE AMP TO PROVIDE THE EXTRA AMP TO A BI-AMPABLE SPEAKER, WHICH IS WHAT I AM DOING JIM P

Hi Gene, thank you for this video. Another great one! I am the lucky owner of the AVC110 from Denon. It's paired with 702S2's from B&W. Currently they are not bi-amped, but I am sure the amp has enough power to drive it. I already have the DB1D sub connected to the system as well. Would you recommend using the bi-amping functionality for this setup? I could, potentially also bi-amp my center speaker (HTM71 S2). Would you bi-amp a center speaker?

Still running my Integra DTR8.8 from 2008 Really the only thing I'm missing with it is 4k HDMI switching. Yea sure, some of the new audio formats too but I don't have all the extra speakers to use Atmos. Was running 7.1 but still haven't hooked up the surrounds in my new house.

I'm using an Arcam AV 750 with Klipsch speakers bi-amped, This produces a,sharper and less rounded, more dynamic sound and generally stronger bass particularly at low volume. Maybe a better stereo image. The listening volume setting is also lower for the same hearing volume.

I'm confused how I would use an open channel as a bi amp? Am I over thinking it or is it more complicated than he made it sound?

I'm using the 3311 bi-amped on jbl northridge e80, and it sounds wayyy better then normal settings, I thought snake oil, but holy moly what a difference with good cables and bananas.

I'm kind of torn, using Yamaha Rx-V683 and Klipsch R28F speakers, no other speakers, just can't decide if it's better with or without :-/

BI - Amping my Arcam AVR 550 caused me no end of issues - I have KEF reference 1's and they are very power hungry, in bi amp mode the AVR would throw a wobbly and cut out - it sounded like it would oscillate before going into protect mode or maybe it was getting to hot ? I would run the amp around 70 on the volume. so fairly loud... I now have 2 PS Audio M-700'S powering the KEF's and all is well in the world.

I am sorry buy why not to bi-amp book-shelf speakers? Anyone can explain more? Great thanks

how do I wire a Sony strdn1080 to klipsch R26fa? Just bought my sony any was going to stay within sony products. but then at the last minute seen the Klipsch and decided to go with the Dolby Atmos t-shirt so now I've got both speakers and I've got the Str dn1080. I don't know if I bought a separate amplifier if that would help run the Dolby Atmos front speakers or not so I would like to hear it what you have to say?

what about bi amping my mains using a denon avr x4700h using klipsch r-28f mains? and also im using separate amps for al my speakers . will be using the denonx4700h as a preamp... thanks for the awesome videos !

Short answer: no. Long answer, if you have a receiver where the power supply is really capable per the massive Denon did, why not? Me, I have a 5 channel amp that is a true monoblock design and used the extra channels to bi amp. The speakers (ATC SCM 19s, you should review!) are 85db efficient and did seem to benefit from the extra juice. I'm now using an Anthem STR integrated, so no more bi amping for me.

Your diagram at 48 seconds is actually incorrect. The front terminals should always go to the Base crossover, and the bi-amp height go to the tweeters

MY SYTEM IS 3.1 LOOKING AT ADDING 2 REAR SPEAKERS. I bi-amped used the surround channel connection for mids. my Pioneer Elite SC-35 on a pair of Wilkins & Bowers 686. I think I notice crisper highs when listening to dts or DD. What I do notice when listening to STEREO output it's very tinny no mid. When my system was not biamped the sound did not have the tinny sound with STEREO output. WHY IS THAT? Also When I use AUTO mcacc. The Amp is +12 on the mids or the surround output.

I just buy yamaha rx-v6a and polk audio signature elite es55 towers. I just buy cables for bi amp. So you tell me I just waste money? Yamaha have stereo mode and bi-amp mode in software. I will use central speaker later and subwoofer. I think no need surround. 2.1 for stereo and 3.1 for film vod and ps5 gaming.

Can u not, go unto the tower, seperate the crossovers and wire directly to the 2 amps?

THANKS FOR THIS INFO 👍. Could you do a video on hooking up the wiring on the back 🤔. I have B&W 802s biwired and recently upgraded to a YAMAHA RX-A 3080 and I would appreciate your help to see if I can make use of the unused channels THANKS 😍😍😍

How about doing bi-amping using an external stereo amp to run woofers and AVR amp to run tweeters.

I own a Denon 2809. I use it only to power the front 2 channels(pure Direct mode). So basically i have 5 channels unused. In this case, is it better if i use surround back channels for Bi amping. My speakers are JBL E80.

Gene, solid advice as always, but I don't agree with the "don't bi-amp small 2-way speakers" advice, at least not with demanding speakers. I had a NAD T775 driving Jamo D830's and even though it was capable of delivering the current needed for the less than optimal impedance dipping to 2,8 Ohm the sound was much better when bi-amped. We A/B tested it a lot and also using a separate power amp. Currently I have a Yamaha RX-A3070 driving floor standing Triangles with even worse impedance characteristics and though the differences are so small I'm not even sure they're really there when driving them with bass management rolling the off at 60 Hz or 80 Hz I have kept the bi-amp setup. Sure could use those channels for two additional Atmos speakers as well as going from 5.2.2 to 7.2.4, so I'm considering buying a separate power amp.

Always curious about this, since you're sharing the same power supply. There's no efficiency delta here at all, you're just using different outputs.

Danny says the double posts are just more Antennas for interference

I have a Denon 6500H which has 11 channels of amplification. I have a 5.1.2 set-up and I'm bi-amping NHT VT2.4 towers in the front. The extra two channels are used for zone 2 outside patio.

Off topic comment but when are we going to see a hands on review of the new Anthem processors and receivers?

I have a Denon AVC-11sr from 2002 and at that time a 3000 euro purchase . Super build , big powersupply , very good for stereo . So what you say is that I can f.i. for stereo ( that's what I am using it for at this moment ) , I can connect the front f.i. to the woofer/mids of my Swan Diva's , and for the tweeters wire it to the surroundconnections on the amp ?

Can I bi amp from one 5 channel external amplifier? I want to use two channels each out to Polk R700. I thing the amp is rated at 90 watts x 5 channels. The last channel will not be used. I was wondering if its as simple as 90 watts x 2 = 180 watts into 4ohm speakers. I did notice that sometimes when power to 4ohm loads the watts increase. I don't want to blow anything up. Amp:5 Channel Monoprice Monolith 90w x5. Avr: Sony AN1000 165w x7.. Maybe I can bi amp using one as a hfa and the other as a lfa?

Hello Gene. I ‘ m bi amping my Emotiva T2 towers with Denon AVRX 6500 H. The other 7 channels go through Emotiva UPA 700. I use it in Auto energy mode. When I need power for music or movies reference level there is.

Thanks Gene. Informative as always. I bi-amp with my Marantz 8805 processor. I can program it to use one of the height outputs as a bi-amp channel. So I run the upper section of my mains (Focus 20/20) with a Rotel RB 1080 and the low end with an RB 1090. Plenty of headroom. As you suggested, it's mainly for cranking 2-channel audio, but also comes into play when watching loud action movies.

I’m using a pioneer vsx-1131 with monitor audio mr4. I haven’t notice any difference with bi-amping but I made it just because avr and speakers were capable off that feature. I really don’t know if my setup worth it.

Thanks for the video! 5.1.4 setup. Marantz sr7012. ATI 1502 amp for front LR. Polk LSIM speakers. No bi amp.

Would a 9-channel Denon x-3700h w/ 105 watts per channel used to bi-amp towers be worthwhile? (Towers are Klipsch RP-8000f II). Would bi-amp make a difference?

Bi-amping with Marantz SR8002 and B&W 703s. It’s a bit more powerful than the 8015 based on your measurements Gene. Every extra sticker costs $500 and/or 50 watts of power:). That 8002 was the best deal of all time in terms of power per dollar.

I have a jvc rx 8000v, and I wanna pick up a set of jbl e80. The jvc has avalible slots for 2 sets of front speakers, and I wanna know if I could just bridge the 2 front channels for left and right respectively, to get more wattage to each speaker. The e80 say 200w rms per tower, so each of the 100w front channels would be combined for 200w per speaker. I'm just worried if the signals would be different for the 2 different output points of the channels

I agree that it should be reserved for higher current amps or flagships. I currently run Revel F208 speakers and much like the 328Be’s really need a decent amount of current to get them singing. While my modest Denon 4520 receiver can do it I’d rather run 5.1 as well as possible than tax the dynamic range. If I had one of the newer generation amplifiers I’d consider bi amping the remaining surround channels for a touch more headroom.

Hi Gene, I have entry level Yamaha rx-v385 5.1 , pair of 300W floor-standing yamaha NS-F160. Do you think Bi-amp" can be an option for me. I did bi-wiring the tower speaker but not sure if bi-amping can be useful.

I have a Denon X4400H that I want to run in stereo only. Would this benefit from bi-amping my speakers or should I just leave as standard connection? Thanks

I have a ATI 3000 amplifier three channel and ave 4400h denon receiver I have two tower Martin Logan speaker 60 xti should I bi wire do do I take off metal plate or i’ll leave it on let me know please

I have 2 sets of Tannoy V4i towers in front of my setup and i have the A and B turn on on my Yamaha reciever, so i have basicaly 4 front speakers ( 2 left and 2 right) doing the 2 front channels. It gives me a super wide soundstage because 2 are on the side of the TV and the other 2 are far on each corner of the room, and then i have 2 tannoy V1i for surround and one Tannoy VCi center channel.. I dont know if im doing a good thing or not.. but i kinda like the sound of it like this.. I dont know if BI-amping and just use 1 set of towers hould give a better sound, i never tried it... My reciever is a entry level old one RX V550, but i love it. Im saving up to upgrade but for now this still kicks S, and im waiting for 2 SVS PB2000pro to arrive next month.. cant wait, i think i have never been so hyped in my life. loooool..

Marantz SR8012. 5.4.2 With bia-amp front L/R- Jbl studio series. Oh yea.. two couch base shakers ( on there own plate amp). In a apt. Lol!... Great share as always Gene! Larry
