How to eliminate turntable vibrations 

Playing through my tv speakers the difference is huge for me, I picked it as soon as track 2 played, track one was so much more full and vibrant

I never use headphones to listen to music. I only use a cheap earphones when I'm on RU-vid in my old laptop and this is how I have listen the tracks in this video. The first track has more mid-bass/bass and the sound is full but is muffled. The second track is thinner but airy and clear.

As soon as I heard the 2nd track it was immediately apparent to me of the differences. Of course I didn't know which included the isolation enhancement, but my obvious preference was the first track. Track 1 had greater tone, clarity, transparency and resolution. I was actually surprised that the differences could be so easily detected.

I liked the second track better actually. It sounded deeper and more airy to me.

I used a heavy walnut cutting board, sized 12x17” from AtHome for $29 and a set of Sorbothane feet ($29) under my table and it made a huge difference. I have old fashioned wood floors over crawl space, so vibration mitigation is always a struggle in my room.

Quickly becoming my favorite RU-vid channel.

The first note on the second track was all I needed to hear to know and I’m using an I phone. Very good demonstration 👍👍

I listened to each track three times because it was hard to define the differences even though I did hear them. My final analysis is that the first track was more balanced, very natural, better tonality and less congested then the second track.

I guessed right. This was still audible even through my iPhone speakers. Track definitely better

BTW, track 1 is fuller and warmer in sound, I guess that's when you used vibration reduction. Track 2 sounds thinner and colder in sound, more digital (I know, there's still digital conversion involved with track 1, but it seems like the 1st track was affected less by YT conversion).

Vibration control is ESSENTIAL for vinyl playback obviously BUT it also has huge benefits for CD players as well.

i liked the first track, more detail and very deep.to me there was big big different with track 2 and also speaker was important to demonstrate this issue .

Waow! I have been using both Isoacoustics aperta, Gaia and the Zazen for years! I remember demonstrating them to my dad (rip) for the first time, when I had the Gaia 3 installed under my loudspeakers, - his jaw dropped to the floor when he heard it. He said it was a day and night difference, you can never go back afterwards. It's the truth, HiFi without Gaia isn't HiFi. What a nice surprise that you actually know about the Isoacoustics de-coupling aswell, my faith in your judgement was greatly improved now! My general experience is, that if you just maintain the weight of the Loudspeaker or turntable within the rated specs of the Isoacouatics you'll get the full benefit. The Zazen 1 is rated for 11 kg, a regular Technics turntable is 9 kg, the Delos with 6 feet is absolute overkill, unless your turntable is made of solid unobtainiun. I'm willing to say that the Delos (compared to Zazen) will be more "dead" with it's increased mass, that will reduce excitations passed on from surface to turntable. But the whole point of the feet is that the block is nearly completely de-coupled and won't be excited by vibrations..! Instead of buying the Delos, all that money should have been thrown into the cartridge instead, and just go for the Zazen, to get the highest ROI. This is my opinion atleast I'm that kinda guy that removes every single Capacitor in my Tube-amp and solder in Mundorf Supreme M-cap Silver-gold-oil instead.

Love your intro & room ambience! This ol' dog couldn't hear any difference using bose noise cancelling ear buds (noise cancel in on position). Another great vlog hearing about, as always, informative info!

Well, that was clear even through RU-vid on my phone. I will definitly get the Delos. I already bought a very stable rack. I will probably also get tje Gaia feet for my speakers. Thank you so much, Guido!

*Important comment!* *De-coupling of counterweight* - I just made a major discovery, a major tweak for any turntable at a LOW cost! having followed Alex Korf's research showing how vibrations are passed on from cartridge to tonearm and ultimately exciting the counterweight. Measuring the counterweight individually with accelerometer and vibrameter shows how the counterweight behaves like an antenna, receiving vibrations. - The counterweight in turn then radiates vibrations and it's own resonances back into the tonearm and cartridge. The tweak is simple, easy and cheap. - You take the counterweight off and coat the 'insides' of it's hole with 100.000 cst Silicone oil and then also coat the tonearm stub where the counterweight attatches. You then put the counterweight back on and drive it back and forth a few times, and rub off any excess silicone oil. Now you have decoupled the counterweight from the Tonearm, this causes major improvement in the 10-20khz region - upper-extension, soundstaging and whatnot, the change is straight up jaw dropping!!! It's like experiencing Gaia for the first time again! This mod is completely reversibel, as the coating can easily be cleaned off with alcohol solvents. Also 100.000 cst is the perfect viscosity, as it will stay in place as a coat, and will not start dripping down. Also - there is no need to be worried that you will somehow "over-dampen" your tonearm as there is absolutely no argument for why vibrations should be passed on to the counterweight. In an ideal world there wouldn't be a counterweight, instead a tonearm long enough that it would be able to balance while the cart is installed - while also exhibiting the perfect VTF for the cartridge. My mod removes the counterweight, without actually having to physically remove it.

Second track has less distortion. The bigger distortion for the turntables is the sound wave from the speakers which created vibration direct to the vinyl plate. (If you are not living over the train station ) This big piece of wood plate with the polished surface just will reflect the sound wave from the speakers and will send it under the turntable to create interference and diffraction and more vibrations on the turntable. Also the homogeneous materials not killing successful vibration. No 1 vibration killer is cast iron , No 2 -is marble , No 3 is chipboard. So If you use chipboard plate , glued from both sides with a rubber foam for gimm exercises will be much more effective.

I liked the sound of both, but I liked track 2 just a little bit more! But I do agree , vibrations make a difference!

I listened with the samsung phones akg tuned earphones. They're pretty flat and detailed and there's a huge difference! From the begining, the first track sounded very precise. So much depth, so much more tonality to the cello. If the recordings were made exactly the same, this is a huge difference!

It also really helps that we start with the well dampened Technics SL-1200 family turntable. I have one too and I love it. Compared to the 3 point spring suspended sub-chasis in a box style turntables like Linn, the special foot isolation eliminates certain outside vibrations, like floor footsteps, really well, much better. But other vibrations, like loud bass in the room are better isolated in a suspended sub-chasis. It's the classic dilemma in HiFi. Everything is a compromise.

Best turntable isolation I ever used is a Minus K platform. Effective & no maintenance.

Definably track #1 sound more open and alive, compare to track #2.Great video Thanks.

thank you for going over this need for dense vibration and good feet. I have recently finished building a media wall for my albums, speakers and electronic components. I built in my floor 15" MTX loudspeakers. Impressive listening to everything...but Albums. I realized today that the basic 1"pine shelving that I used to make my built in electronics stand transfers a TON of vibration through the wood to the record player. ugh. the shelf to the touch can be felt vibrating. such an oversight. Your information has given me a new direction to take.

The difference is in the equalisation of sound. Track 1 was more open and spacious sounding. Track two had better dynamics and weight to the sound. In hi-fi terms track one sounds more impressive. In terms of musicality track 2 is better (listen to the cello's depth of tone). Both tracks had their pros and cons. Isolation tweaks can be a double edged sword where they improve sound in one aspect, and degrade in another. One of the most neutral and effective isolation products is a slab of decoupled MDF. I know I know its not an exotic or expensive solution but tends to be tonally neutral due to its flat Q in the midrange without any peaks. Solid wood (depending on type) has tend to have Q peaks. Another way of looking at it is that isolation devices perform like mechanical graphic equalisers which is dependent on the q of the isolating material. This results in the emphasis of certain frequencies at the expense of others.

Hi, I picked the correct track even listening using an iPhone ! I have had a problem with vibration, I think it’s a bad floor board area under my rack. The room is carpeted throughout. Even when i just tapped my foot the tone arm on my LP12 jumped.My final solution was to place washing machine vibration dampers ( 4 ) under a piece of 24mm thick MDF board ( 600 x 400mm ) on top of which I placed 8 sorbathane hemispheres on top of which was my very heavy highly recommended 5 shelf rack. The linn LP12 was placed on the top shelf, with the feet replaced with 4 more a sorbathane hemispheres. I can now jump next to the rack with problems. You have to use the correct size and hardness sorbathane hemispheres for the weight of your equipment. Everything is now ok and sounds great. Regards Richard Herbert

I definitely notice the difference between track 1 and 2, track 1 was much Fuller! As a kicker, I am listening to this Thru my speakers on my Galaxy S20SE! So if I can hear the difference how much more with a good speaker 🔊 system. Thank you for the demonstration.

Sorbothane is an incredible isolator. Audioquest sells it in small sheets. I have my turntable on a Mission isolation platform that must be 30 years old. It has 4 round feet made of plastic & Sorbothane. It's worked very well. Don't think it cost me more than $40 back then but if you are wealthy audiophile or an idiot like me I would probably give this wood isolation board a good look and possibly buy it. Even though I am very sure that my board is at least 90% as good as this big one. Some thing about the Sobothane.

I wasn't expecting a lot, but even with speakers the first track seemed to be vaguely better, so I switched to headphones: the difference seems to be at the same time small and big, small when you consider the whole music, big when you consider each note. It is quite clear to me in my synaesthesia image: each note here is like a bamboo cane, but in the first case they are tightly packed, while in the second they are just a loose stack laid to the corner of a room.

Much more Bloom! Track One

Bass was clean and louder too Track 2 was compressed. I have tried using PU rods under my turntable by using heavy block of wood approx 10kg and it works better 10yrs back.

My friend the best tweak I made to my 1200g . Thank you

The first track did sound better to me. Cant explain the difference,the second one sounded good,just maybe slightly cut off or muted a little. Either way thanks for the videos, it does help some of us to make a more educated decision on cost versus benefits

The hi-fi shop I normally go to did a test by attaching 4 GAIA III feet to a fairly inexpensive maple cutting board. Did their test with a Planar 3 turntable. Yes, the difference was clear. Man I love those GAIA III feet. I use them on my Monitor Audio floor standers and it took about 3 seconds to hear the difference and my speakers are not high end. As far as my turntable, I have a sprung turntable and I made a 2 part wall mounted shelf. It's 2 parts so I can adjust the level of the upper shelf. Under the adjusting feet use sorbothane pads and then under the turntables feet I made 4 feet using the same sorbothane pads sandwiched between pieces of aluminum round bar. They look nice and for me they really seem to work.

I've had the poor man solution: an IKEA's bamboo wood plain with isolation feet under my Rega P3. Even if not efficient as the Delos I've had a nice improvement on sound. Nice one Guido.

Headphones or speakers, after all the sound goes through to make it to this page, who knows what you are hearing? However, take a vibration meter to the surface of a record and you will see a great deal of difference. While the turntable suspension is the most critical, adding isolation devices such as this does help. Even if the sound doesn't change, it is such a pleasure to have someone stomp their foot or unintentionally tap the shelf the turntable is on and the record does not skip at all. THAT is why I isolate my turntable (which already has a suspension such that I can press my finger on the base and bounce it and the needle doesn't move at all).

I’ve bought two granite work top savers and some isolating spikes,with pieces of rubber in between the two granite work top savers.👍

Yes, I was able to hear a difference.

Thank you as always. I hear a clear difference in track 1 & 2 ... I find track 1 more detailed. So clearly 1 to me. Peace and love and of course High end. Greetings from the Netherlands Limburg Maastricht. Music is born Analog ... ✌😘👌👍😉

Yes. The first track I guessed it right has more openness and wider soundstage

Whoa. I was thinking that buying that big chunk of wood was a bit too excessive but the difference is freakin noticeable! Lets say that track 2 sounds as if Starker was playing the cello in the bathroom or en empty warehouse , a lot of echo and reverb, the sound so thin and distant. Whereas on Track 1 it sounds as if he was in the room. Although, I must say, vinyl's surface noise was also more noticeable. Holy Moly.

I have butcher block acoustics and it made a big difference for my set up. Thanks for all your great videos!

Thanks for all your nice videos. Amazing. I watch your videos a lot. What I want to ask is if you do have any experience with walker audio products. They are very expensive. Do they really improve or is it snake oil? I cannot test them. Would be glad to hear about it. Thank you.

Well, I preferred track #2, listening through the earphone connected to the i-phone ... so that’s nor trustful. I do use Gaia isoacoustics isolators under my speakers, and they really improve the sound as compared to nothing. But compared to the original speaker spikes, there’s not much difference ... I also use a wood rack, specifically made for audio equipments, under my gear, and isolator feet under the TT, but haven’t tried this isoacoustics maple. I think I’ll try that! Great video, as usual!!

Yes I agree the iso feet under my kef reference 5 made a great difference so I put some under a nice bit of wood then put on my technics sl 1200 g also worth the money . ISO feet can be expensive but if your gear is 30k than it’s not so expensive for what you get back in sound

One of the best free d.i.y. solutions and cure i heard regarding turntable isolations and vibrations was from a very old guy i knew. He had his turntable installed in a room opposite to his listening and equipment area. He had designed his own special damped arm lift/ cueing device . Timed to perfection so by the time he got to his listening seat the tone arm just met the run in groove of the record . He used special low loss, long run tonearm phono signal cable of his own making connected to the pre amp in the other room . I wish now i had asked him more details of what he did and actually used . Sadly too late now as he has now passed away .

I’ve been thinking about building a platform like that but I was going to use the Gaia feet so I could adjust the height and level of the platform

Uh, that's way too much to spend on a chunk of wood with the nice feet. I honestly could not tell the difference as it may just be the way you recorded them. I've been suspending my turntables for years (since the 80s) and for me and it works great. I have my turntables on a piece of wood with an inner tube between it and the hanging platform. I use a small piece of a plastic tube under the inner tube to relieve and possible pressure on the inside circle of the tube. I use Sorbothane Vibration Isolation Circular Pad 50 Duro .25 in thick under each footpad for extra vibration control. And yes, the platform is completely level.

There is a big difference to my ears, more detail with. My solution is - I had a slab of granite cut, this is mounted on sorbothane feet. The turntable sits on the granite on spikes

I did have a preference for Track 1. It seemed (for lack of a better word) fuller. I hear that tennis balls, sawed precisely in half, are a great (and cheap) dampening solution. (3 half tennis balls, not 4.) (And I listened to the compressed RU-vid sound of your video on an old MacBook Pro connected to Creative X-Fi USB external sound card (set to flat, i.e. Crystalizer and CMSS-3D both switched off) connected to Cambridge SoundWorks PCWorks 2.1 powered speakers. So not exactly a "high end" setup, but, apparently, revealing/resolving enough...)

Bravo bella prova !!!!!

I heard a tiny difference but I don't know if it's worth the cost. But I like your passion!

Thanks for video. I got bass loop on my Gates TT and looking for solution I found your video. From your 2 samples I don’t like neither. The first one has a lot of echoes probably because of wooden platform which has some resonance, second track missing details of this nice record. Hope your EMT sounds better.

I liked track 2 better the first listen through. But the second listen through I listened to track 2 first and then I listened to track 1 and liked it better. In Track 1 if feels as if the instrument is right in the room, and Track 2 sounds like a really relaly nice recording of the same instrument.

I had some wood lying around (not walnut). I, as a fun project, tried to make my own cheap Isoacoustic Delos replica. It's not as heavy, used superspikes instead of dempers but I was very surprised at the impact. It made a noticable improvement already. A little more detail and wider sound. So I believe the real Delos could make a even better improvement. But with less than 100 euro investment I am very pleased with the improvent it made.

Listen to it on my cell speakers, very similar but liked the second one, then I did it again with ear phones, still similar But now the second one seemed to resonate at some points, so now the first one sounded better

Oh yeah! Just through my secondary system/computer/stereo I could *CLEARLY* tell the difference, no comparison! The first track was so open, full, and lovely, absolutely. However, $500 is just way too much for me. Interestingly, I just added a long piece of slate underneath my turntable because I wanted more room to put my two phono amps, the IFI Phono 2 and the all tube LittleBear T11. What was unexpected was that on my system, suddenly all my albums sounded brighter and it kind of alarmed me. I realized that the resonance of the slate was apparently greatly affecting the sound, kind of a 'Ringing' effect. I had that once on a Rega TT I had about 40 years ago with a glass platter (bad idea!) So, yes, I also was now looking into some kind of dampening. Many have suggested the dense wooden blocks you can get from Ikea. BUT... I remembered that I had ordered these little 2x2 inch squares which were specifically made to control TT vibrations. I put a set under the feet of the TT, between the TT and the slate. I (THANKFULLY!) immediately noticed a much better, non-bright sound. I have another 3 left so I put 2 under each of the 3 feet of the British Revolver TT I have. Ah... now, everything sounds much better. I'm not sure if I should also pursue even more dampening, but for now, that fairly inexpensive ($25 for 12 pieces - I also put 4 under the slate between the top of my rack and the slate) adjustment REALLY made a big difference. I wonder if i can indeed dial it in even better, but WITHOUT spending $500! 😁

I’ve got a 1 inch particleboard table top then 1 1/4“ x 3“ diameter rubber stoppers underneath a slab of granite. Then I have magnetic floating feet on top of the granite supporting a 9mm acrylic sheet with the turntable on top of rubber stoppers on top of that acrylic.

For my Turntable a combination of a heavier plinth( 7.5 Kg instead of 1kg), New carbon steel sub-chassis suspension springs, and the most dramatic improvement came from installing Isonoe Isolation feet( not cheap). MY TT rack sits on Parquet, which until adding the Isonoe feet, meant I could not walk near the TT as the Tonearm would bounce over the record ( typical experience with a Suspended sub chassis TT on Parquet). Now I can jump next to the TT and there is no reaction. Originally the feet were produced for DJs TTs so they are designed for extreme vibration environments.

If you're looking for a decent but cheaper alternative for the Isoaccoustics Delos, you should try a thick wooden chopping board like the Ikea Aptitlig and put some Vibrapods under it. By adding Vibrapod Cones, you can improve your improvised isolation platform even further.

for me the second track sounded better but only marginally. I was listening on my PC/speakers/headphones setup, maybe on my hifi system it would be different. For the price I would be looking at getting a separate phono stage instead. As mentioned elsewhere, a wooden bamboo chopping board like the Ikea Aptitlig with some gel feet is a cheap alternative. If it doesnt work out you can always use it in the kitchen

Some episodes ago, you sell your old phono amp. Do you got another one in the meantime? Do you know BLUE AMP? I would like to get some information about it. BR

yes even with a very low quality headphone connected on my computer I could identify a slightly better sound on track 1 : more aerial , better definition .not easy but if your ears are trained you can hear it . daniel

The first track sounds louder and more open but with an edge of grit, the second track sounds a bit more closed in but smoother. I prefered track 1. This is a recording I listen return to quite often...I think the acoustics of our rooms has a much bigger impact than anything else. My room is deader and helps the recording.

Question, I’m getting a rumbling bass sound which gets louder as I turn up the volume would the wood plank or isolation feet cure this?

You could hear some difference in track one.... but you need to remove the rubber bottom feet from the sl1200 for a solid foot to couple the TT to the iso platform for it to work as designed

All I am saying is give springs a chance. Try spring iso feet for turntable AND speakers. Even suggest removing springs for optimal effect. Read the comments on A-zon.

I have a project Xtension 9 and I feel the isolation is really good. Maybe I can get even more??? Thoughts on isolation for power amplifier's??

Whoa i could tell the difference

Minus K suspension is the only thing I’ve found to work, it’s passive and uses science in its design. Built and designed for microscopes. Also great under tube equipment.

Picked #1 listening to video on inexpensive chromebook .

I eliminated the cost issue by purchasing a 2.5 inch thick, solid maple cutting board. Thus, I cut the "Audiophile" markup dramatically! Maple is maple. The only difference is you are paying a premium because it is an audiophile product! I then added vibration pads. It is mounted to my wall with a shelf support I designed. All costing less than $100 US, and does the exact same thing for much less! You can also do the same with a slab of marble! The denser the material the better (maple is denser than walnut, and marble....you get the point)! Just an FYI to save you some money!

In the case it make no difference, you can use it as the most beautiful and comfortable cutting board....salut Richard

Why not a 20mm thick granite slab ?

The first track was boomier. The second track was tighter and had more detail.

TRK 1 was a fuller sound. TRK 2 the highs were a bit loose. That’s just me

Hey, I did hear that track 1 is slightly better than track2. That’s my opinion and that’s what I heard, I am using my iPad Pro via usb to AQ Dragonfly RED feeding Schiit Preamp

@7:51 track 1 @8:35 track 2

Worth it for a Rega, lower level listen only 🤔 (the Zazen 1 In this case)

It depends on the rest of your tract. And personal preferences. With Clearaudio turntable and MC cart thru solid state linear phono to Harbeth 30.2 monitors I choose more relaxed version without dellos. Cause I'm already have a sufficient level of transparency.

I built my own suspension table with 2 sheets of mdr glued together 5cm. I put 4 brass feet (point). Since then i can jump in my room and the table is not bothered. Slight improvement with the sound. 30 euro and 2h of work to make it pretty. That + a 25 euro acrylic mat and all the vibration is gone.

Why did you say the Maple was better than the Walnut version? I have a VPI Prime Signature and I am looking to purchase one.

I've found wood to have a lot of resonance. Granted, it's a highly pleasant resonance. It's one of the reasons they make drums out of wood.

Can i make a wood box with two 45 lbs cast iron weight plates in it and attach 4 rubber anti vibration legs for washer/dryer? It looks the same .

Best stereo furniture for the price/performance ratio is the Ikea Lack table, for the turntable you cut out the bottom ofthe tabletop by a large round circle and take ot the inbetween material. You can stack the tables on each other, though I recommend that you secure them so they dont slip off, happened to me. Best place to put a turntable furniture is the wall. Most often will the floor move and the the movement is not equal when placing the furniture against a wall so the turntable gets a rocking lateral movement. Thats death to good sound especially on a suspended turntable like Linn LP12 that can take vertical movement, but are sensitive to lateral movement I have made three sturdy wall shelf holders by square steel tubing 50x50 mm in the shape of a 90 deg angle, in the corner a short strengthening ”fillet” made by an added short piece of square tubing, drill holes for mounting on the vertical piece that is resting on the floor, drill two holes through the horizontal piece at a good location, so there will be room for cables in the back, use threaded rod like M10 and nuts, sharpen the upper end and adjust to a level position place upper shelf onto the spike rods, the lower shelfs need some holes and will be positioned hanging on the rod and nuts. I made mine so it will take a load of 300 kg, i have full timber walls. Shelfs can be adjusted or added easily when things change. On the upper shelf I have two turntables, 65 kg Platine Verdier and one quite heavy EMT938 but no worries with M10 french timber screws holding it to the wall

Track i2 is bit hollow or empty to me. The block does improve the sound quality.

I have 2 real good fool-proof solutions. 1 I did. The other is a bit harder. 1: Wall mount with isolation hardware on butcherblock . 2: Ceiling mount with chains and marble stand. I did the wall mount and wish you could see the picture.

I'm not sure about that? you better putting it on a piece of one or two pieces of one 1" cellulose foam, taking the feet of the turntable so it's lying flat. our use those feet I suggested the ones using tungsten powder and squash balls. A block of bolster Wood would be better than that heavy piece of wood as well But the biggest improvement with a turntable like yours is the rip out the transformer and power circuit board and put it in a separate case like a PC power supply case, away from the unit connecting to with a BNC connectors to the turntable or you could use one bnc, 1 BNC would be for the power switch if you kept it on board the second being for the power cable to the main circuit board, use a shielded cable from the power supply case to the turntable with a x2 275v + 1uF ceramic capacitor across going to the power switch BNC connector, and a ferrite bead on the end of the cable going to the turntable as well. Ideally when putting the power supply in the PC power supply case find one with an ice socket and filter assembly already attached and use a short thick an ice mains power cable to the socket. you might want to consider bypassing the fuse or swapping it out for silver fuse would be better using silver wire in the fuse wire, and having the power switch on the power supply not on the turntable you could just leave it in position disconnected for Aesthetics reasons on the turntable. Then you would just need the One BNC connector use a 75 ohm BNC connectors not 50 Ohm's. That be a lot better than anything else you do to it or use. The transformer does have some mechanical and electrical shielding but not really sufficient you could try using some silicone grommets instead of the rubber grommets would help quite a bit as well if you don't want to take it out, and swap the fuse out for Silver same value and put a 1uF but this has to be a X2 275v + safety capacitor across the main terminals from the the main lead feeding to the power board. You could slab some Blu-Tack underneath the turntable roll it on and just leave the plastic film on the outside so it doesn't get dirty take the other one off, place underneath where the transformer is and underneath the centre, actually Blu-Tack makes fantastic feet better than anything else just roll them into 2" balls this can't take a great amount of weight on its own but it would hold a Technics turntable. to use for your speakers blu tack put them in the little disc candle trays near to the top place a felt or some type of disc on top use bolts instead of spikes. Blu-Tack has been found to be the best acoustic material out there better than rubbers or plastics not sure if it's better than tungsten powder I don't think so. That's enough for me tonight

would the delos help with playing via bt or just through speakers?

Definitely different between tracks. If i may suggest something. The problem with the way your doing the test with a microphone or cell phone it blurs the test results because your listening to a good part of the sound bouncing around in the room with a lower quality microphone. Booming bass in obe test could simply sound deeper in a recording of the room with the speakers in the room. The correct way to do this kind of test in disconnect the turn table from your preamp and plug the turntable and phono stage into an analog to usb digital decoder (about $40) and using a usb cable pluged into a laptop record the results to the laptop, this way you hear the turntable directly without interference of the room or a low quality microphone blurring the results. The software to do this is free and plentiful. Many people to this to archive there records.

If you have a solid built wall fit a turntable wall shelf cheaper and especially if you have a suspended wooden floor more effective in my opinion.

It can be said very short: Philips GA 212.

Track two for me. Sounded tighter or hot with more resonances

Yea dump the Delos for so many reasons it's not worth getting into all of it (it would take too long). I've seen Starker three times in performance. I heard live a concert he did in Oak park, IL that Naim audio recorded for their label. I heard the master tape on the machine that made the recording and heard it compared to the compact disc( a nice recording for those who never listen to anything but the Bach Una. Suites). Not to mention I heard him teach and play at Indiana University where he taught master classes next door to where my brother studied viola. My brother heard him all the time. I have owned this recording since the early eighties and own three different versions plus cds. From what I heard the space clarity, and resonance in the first track was less so. Also their are moments in the recordings that you can here the subway going by , a bus or something like a bus pulling away. Theirs so much ambience in these recordings. But if you here something different, its your ears and that's who you have to impress. One more thing, Starker is pronounced phonetically " Jahnosh Shtarker". I think I spelled that right.

Track 1 all the way

By the time the music was compressed by RU-vid and then I hear them on my Bose Sound Link (yes that's what's on my PC for that I use for 90% on voice content and it is fine for that) there is no difference so I skipped trough that part. I never listen to comparisons of this kind because that is something I do not believe that can work on a RU-vid channel. Regarding the tweak, yes I believe that will work but unless you are also interested in audio jewellery I would use a concrete slab (painted of course with some dampening feet, preferable not from the audio industry to get that 1000% saving. I think this product looks beautiful and for what it is (audio jewellery) it is worth its money but for $700,- you are getting in to the territory where Mitutoyo (makers of high end callipers etc.) is offering professional solutions for laboratory precision scales to name an example. With that kind of money in play my trust would go to those guys. Pro-Tip for shoestring audio enthusiast: Vintage Dual turntables have this build in. There is a reason they have a following. Here are some models that can stand their ground with High end stuff: 1019 for nostalgic reasons but wow, is it charismatic; 1229 = the best idler wheel TT they made; 701; 721; 704 (the 7 series are direct drive)

Vibrapods and Orea can be used under original feet or do they work as replacement feet?

I had a wood pecker problem, so I went with the concrete version.

Can you send links to your recommendations please

The isolation platforms called zaZen are also another possible solution; and those isolation platforms are a bit less expensive!🔉🎵🎶
