@willwill5595 Год назад

Almost forgot! Thank you so very much for the comparisons! I've been punching in comparison between 300B and 2a3 for about 2 or 3 years on RU-vid! I think this is the second comparison I have found!

@Aerohigh Год назад

All the younger members in my family prefer the warmer fuller 300b, as for the older (above 70 yrs) members they like the 2A3 Tubes.

@flex-cx9bi Год назад

In this application I prefer the more neutral tone of 300B, but it is completely impossible to say if one type of tube is better than the other since 300B is twice as hard to drive than 2A3 so it very much depends on how strong the driver tube is and how much current is run through that tube. Both 300B and 2A3 can sound fantastic when the surrounding conditions are optimized. A change of power cord would probably make more of a difference than the difference between the 300B and 2A3 used in this test and this amplifier.

@xzing7 Год назад

2A3 Tubes sounds more refreshing to my Ear's and is more suited to eclectic Genre's of musical styles, instruments and voices. The 300 B Tubes would be put down for that long marathon listening sessions. Excellent channel, LIKED AND SUBSCRIBED 👍

@hrvojekant9415 9 месяцев назад

@Revelator2025 Год назад

300B keep coherent with dynamic passages. So I choose the 300Bs. Vocals do seem more articulated and present with the 2A3 however. (Both sound fantastic though…). You did a wonderful a/b edit. Greatly appreciated!

@soundsgood12 10 месяцев назад

The 2a3 to my ears is more nuanced/detailed, more space/air, good micro dynamics can listen deeper into the whole event soundstage which allows hearing interplay between instruments, soundstage is also a bit larger. Thanks for the demo!

@VirtualHiFi 10 месяцев назад

@aranor1 Год назад

Thank you for posting this video. I found the 300B a bit more luscious sounding. While both tube choices sound excellent, I prefer the 300B.

@stevewestwood4832 Год назад

Thanks for posting and giving is this useful insight. Both sounded beautiful on my Senn 650’s but the 300B edged it for me.

@klaushollinetz7494 Год назад

I prefer the 2A3, but it seems to struggle with the output level sometimes. Interesting comparison on a very nice system.

@danbuffington75 7 месяцев назад

The 2A3 fits my hearing better. I have worked in noisy environments a long time and notice that the lower frequencies all seem "muddy" due to my hearing loss. The 300B sounds muddy to me because of that. This is a good demo because I did not know about the 2A3 tube. I appreciate the effort you put into this video. Thanks!

@VirtualHiFi 7 месяцев назад

Thank you for your positive feedback :) Yes 2A3 are considered to be more natural and open and less colouring while still very analogue. But require high efficinecy simple to drive spekaers :)

@Jil8840 Год назад

Great test.

@VirtualHiFi Год назад

Thank you for your very kind words ☺️

@westernartifact580 Год назад

Close. Hard to say for sure. Perhaps more separation of instruments in the midrange with 300b. I agree that 300b sound fuller and more out in the room but hard to tell for sure from here. Thanks for posting. Love the new recording system. Sounds great.

@VirtualHiFi Год назад

Thank you for your very positive comment and I also would choose the 300b here. New videos will come soon 😉

@Flevoman Год назад

First if all - what a absolutely wonderful sounding system . Lovely musical choices as well .Favourite tube ?That’s a tough call. They are bot fabulous . Based on this RU-vid video I think I would have to pick choose the 300B for its lovely natural tonality . Lucky you that you own such gorgeous sounding system

@VirtualHiFi 9 месяцев назад

Many thanks! Such positive feedback gives me plenty of energy going forward ;)

@singaporehifiblog 6 месяцев назад

300B for me. It adds more power to the bass and has a more balanced tone to my ears. Thanks for taking the effort!

@VirtualHiFi 6 месяцев назад

Thank you for the comment. So it is apparent now there are 2a3 and 300b teams

@gjnbouwmeester5860 Год назад

NICE! Lovely to hear the two tubes next to each other in this system:-) Thanks for the video. The fuller bottom of the 300b is probably more of a power issue besides the 'character' of the type? 8 Watts compared to 3,5W from the 2A3? Maybe when the 2A3's would be tested in PSE then the power would be sort of fair. 45's in PSE could also be a nice test compared to a GOOD 2A3SE Personally i prefer the 2A3, but from another making, LoL I play my power amp with a pair really nice sounding Emission Labs tubes. Those bring some extra 'bottom' and mid/high refinement! compared to the Sovtek. Once i had a set of the Cube Audio F8's in DIY-box version at my home powered with 2A3SE or 45SE power amps. WILD!! LMAO Would love to see and hear more from you and the tube comparisons:-)

@HEZIBASS1 22 дня назад

No doubt for me, the 300B all the way!

@davidbee8178 Год назад

IF I'm not mistaken these Jazzon speakers are about 93db sensitive? - the power of the 300B tubes seemed to do better than the 2A3's here in this audition BUT given a 100db or more sensitive speaker, I bet the A3's would give the 300B's a run for their money :-) and maybe do even better in the bass . . . obviously it is MOST difficult to make a proper assessment given the effect the viewers' playback system :-) REALLY enjoyed the choice of music and it helped discern certain subtleties.

@KimvonEssen 9 месяцев назад

I had the 300B set monoblocks before, but changed to 2A3 monoblocks, and I will never change again!. The 2A3 has a much more refined and elegant presentation through my full range speakers.

@VirtualHiFi 9 месяцев назад

I heard some great 2A3 sounding systems so I totally understand you. 2A3 can be supernatural dynamic and magical

@pavelkastanek3328 Год назад

Hello, I have a jazzon and I had a comparison from you with the Tektron 211 and my KR 842vhd. What are the differences between Tektron 211 and Tektron 300B please. Thanks for the reply.

@dmark2639 8 месяцев назад

Both sounded really good to me. I thought the 300b was a little richer and fuller sounding harmonically in the midrange, but the 2A3 had slightly more clarity. The 300b midrange seemed to take a step foward too, while the 2A3 seemed a little less "forward". For me, I'd probably opt for the 300b for it's glowing, warm midrange, but i would also be very happy with the 2A3 too.

@VirtualHiFi 8 месяцев назад

Thank you for sharing your opinion ;)

@fullranger3435 Год назад

The A3 is a little more clear and precise. I'll call it refinement. 300B, on the other hand comes with a certain hint of more power which becomes more obvious with the string orchestra. But, trading-off some clarity and precision. The sound is a little hazier, compared to the A3. Some may take it as "lushness" or "warmth". It is a coloration that would rather go unnoticed outside a test like this. What I'd like to stress is that this loudspeaker is definitely better than the Qualio IQs. Great videos and comparisons. Thanks for the treat.

@hgroton2078 Год назад

300b for me. Thanks

@aexexer627 Год назад

I liked 2A3 ..it is for jazz music...mid ranges more powerful for me..but both of them are extra good..hard to tell difference normally.. maybe you can compare one day mosfet amps-tube amps... thanx...

@SuperMadpom Год назад

Had a couple of listen through on Dunu Zen Pro IEM (Single Dynamic Driver reviewed as being neutral) and ifi gryphon DAC/headphone amp described as just on the warm side of neutral. 300B would win for longer more relaxed listening sessions. 2A3 Feels like it would be fatiguing. 300B maybe adding some richness to the bass whilst knocking a touch of harshness of some treble notes. Could be that the 300B looks terrible in a lab test, but if it helps you unwind when listening then probably a good, if personal choice for many.

@tictocbang7443 7 месяцев назад

I've had quite a few amps with both of these tubes, and the sound here echoes what I've experienced. The 300B is so luscious and seductive, but doesn't sound as direct and organic (to me, of course) as the 2A3.

@VirtualHiFi 7 месяцев назад

I agree with your opinion. Thank you for your comment :)

@Tom_the_great Год назад

Did both tubes came from a different manufacturer? I’d like to hear some Western Electric 300b’s compared to something like the Electro Harmonix 300b’s

@Manu_Nayar 8 месяцев назад

I have been using both 2A3 and 300b since 2007 though Lowther speaker set up. 2A3 is best for Lowther. Now this one I liked 300b sound.

@VirtualHiFi 8 месяцев назад

Thank you for sharing

@explorinlearnindoing5462 Год назад

Great editing! On my old Samsung s7 phone, no headphones; clearly a difference. I could hear (with closed eyes) exactly when it was switched. 300B was my first preference; more natural..., real, analogue And more "in phase" But also more 2d. The 2a3 was less natural, more diffuse, but also more alive and 3d. Btw; what was the first song??

@VirtualHiFi Год назад

Thank you for your very kind words and opinion. I would go for 300b if I were to choose one one pair.

@vespass225 9 месяцев назад

I would agree with @flex-cx9bi on this. Even if the amp accepts both 2A3 and 300B;s it is for sure not really optimized for both of them, and the driver tube may have just the right drive for 2A3, but being to weak driver for 300B, thus not allowing 300B to show its true potential.

@michaelclyndsell5372 Год назад

The difference in sound quality between the two is very small, both are very good I tend to listen to the music being played more than an audiophile does.

@JRadian Год назад

Do we know the output transformer primary impedance? With fixed output transformer, one cannot optimize the amp for both 2A3 and 300B..

@dannyalvens5418 4 месяца назад

2.5k works nice on both tubes...If you were to increase the primary to lets say 5k,You would lose some power,But,You would have less distortion and higher fidelity....5k is usually used on the 45. Which is a nice tube...You are talking about optimizing the amp for the tube,Rather than a swiss army amp so to speak..With a few switches in the circuit you can come pretty close....One thing that would be considered sacrilege in the audio circles is using Negative feedback with a DHT..I am all for it.Reason being,you can get a wider bandwidth and cut down on distortion by using two resistors, You wouldn't need to buy a ten pound output transformer for each channel on a 300b amplifier,You could have the same power, bandwidth, and less distortion with a three to five pound transformer. Where people mess up with NF they use too much,So it sucks the life and details out of the sound...

@polarfilm5858 Год назад

My personal choice is 300B, have more body and correct staging.

@petranto Год назад

The amp on the left is Tsakiridis Devices Aeolos ?

@christophermoore7707 Год назад

300B for the instrumental. 2A3 for voice... Finally answered

@glenschneider5978 Год назад

Totally agree here. For me the texture in and around the vocals come through better in the 2A3; but for all else I prefer the 300s

@user-od9iz9cv1w Год назад

Listening on a good laptop with Grado headphones I cannot hear enough difference to justify taking the time or money to change tubes. I slightly prefer the 2A3. The 300B sounds slightly off by comparison. Both have a nice sound in this system.

@Patraquashe Год назад

Hard to say for me honestly. I think I might prefer the 300B sound more.

@klepp19 Год назад

Is Tektron quiet for high sensitive speakers?

@svtcontour 10 месяцев назад

Its hard to tell from the recording as the stereo sounds a big congested - but I think the 300B. Listening to this youtube vid on a pair of Kef LS50 as my computer nearfield monitors driven by an Infineon based class D amp.

@VirtualHiFi 10 месяцев назад

Thank you for sharing. Yes I likes the 300b in my living room very much as well due to big reverb. Due to rich midrange and coloration it helped get very good balance.

@willwill5595 Год назад

High frequency are close, mids sound more forward on 300B but I think the 2a3 sounds a bit sweeter with voice! 300B has more bass! Long listening might be a tad easier with the 2a3! Would love to hear Amy Winehouse, Bjork, or Beyonce!

@jensongdi 3 месяца назад

2a3 sounds more narrow? Uptight 300b just sounds open, lays it out

@gregj.gotham4402 6 месяцев назад

I’ve got to admit I’d desire an amp of each 300b another of 2A3 they both are very reactive to different music. Just beautiful both are in reproducing musical instruments. It’s to hard to tell from my iPhone. I need an Invite for true critical listening

@interesting7906 Год назад

At times the 2a3 sounds 'shouty' in the midrange and for example the voice lacks the last lowest freq present in the 300b, on the other hand the 300b seems a little flat although the mid low freq are more extended,

@dmark2639 8 месяцев назад

I agree the 2A3 had a few "shouty" moments. But it could also be those speakers with the whizzer cones, too. I would really have to here the 2A3s with a few different speakers.

@user-id8lb5ec1y 11 месяцев назад

The sound of the 300B jumps forward and has a deeper, more lustrous sound.

@VirtualHiFi 6 месяцев назад

@sarahX.. 7 месяцев назад

Ok so from simply listening on my Logitech equipped high-end PC after 2 minutes this is what i immediately heard. Just from a basic frequency range perspective.... In his video it seems 2A3 was emphasizing frequencies more at approx 1 or 2kHz, and also more open higher up. Whereas 300B seems to be emphasizing more the lower mid-range and more soft on top. Richer more full sound.

@sarahX.. 7 месяцев назад

The second song (Flute? clarinet?) was hurting my ears especially with 2A3!!

@VirtualHiFi 7 месяцев назад

Thanks for sharing. Yes 2a3 is more lively and can be spunky in Some systems. 300b is safer but mellower choice. It's all about the preferences and particular system ;)

@garth56 10 месяцев назад

I always find the 300B a bit syrupy whilst the 2A3 a little cleaner. However neither of these triodes are my fav with the 211 and 845 in third place the GM70 in second and it's bigger brother the GM 100. I'm going to say something quite controversial here one of the best power tubes done right is the humble EL84 and in the right amplifier will outstrip many of these super expensive tubes. I'm building a OTL EL84 mono power amps, my own design, I hope to post something when I get something worked out 🙂

@erlons6918 Год назад

the 300b is presented a sound rich in harmonics very musically pleasing, as if it had absolutely no local or global feedback line in the electronic circuit, saying to electrons you are free enjoy the party have fun with the music, the 2a3 presented a slightly less hot dynamic compared to 300b with more restrained harmonics..

@bobsmoot8454 11 месяцев назад

If me the music was very nice, but without each tube playing the same piece I think to be difficult to ascertain the nuances. Even if each tubes music selection contained the same instruments it would still be dependent on mics used and the recording environment. That said, I enjoyed the demo, I’m assuming the music selections were purposely selected for how the matched or showed the tubes sound best

@VirtualHiFi 11 месяцев назад

Thank you for the feedback. I will do both ways for my videos for you guys to have the best reference there is ;)

@rrb_canada 9 месяцев назад

In this setup : 300B: richer sound, more texture, more bass, more fatigue free. 2A3: thinner sound, a bit restraint, less refined, gives the impression of having more micro details...

Best sound IMHO is with a 45 tube…. which you also can run with the Tektron. But maybe your speakers need a bit too much juice a 45 can give. On horns the 45 sounds best to my ears. Great comparison anyway thank you!

@ron101346 7 месяцев назад

300b's are slightly fuller, the 2A3's are more refined. The differences are miniscule. Pay's your money, take's your choice. Something to consider: top quality 2A3s are about 1/5'th the cost of comparable 300bs.

@VirtualHiFi 7 месяцев назад

Thank you for your comment. indeed the price factor is important to consider 🙂

@512bb Год назад

They both sound terrific, however there are far too many variables to make a definitive determination if one is intellectually honest...And when you consider this is over the net then it all goes out the window but this is defiantly worthy of a listen.

@stevenconnectingtogether6703 5 месяцев назад

2a3 has more seperate layers in vocal & background. Instead 300b just more fuller 😊

@markbajkowski1171 Год назад

To me, 300B seems to be more pure tonally, while 2A3 seems to have an audibly detectable higher 2nd harmonics content. In other words, 2A3 sounds more "tube like".

@bachiano1 6 месяцев назад

2A3 clarity is hard to beat. If you want to beat the 2A3 - try a 45 . Then you get the lusciousness of the 300b with better clarity than the 2A3. Just my opinion.

The 2A3's bass sounds tighter than the 300B to my ears/earphones. The mids & highs sound nearly identical but the 2A3s sound more transparent, more invisible. Of course RU-vid is not the best method with which to do audio comparison tests & hearing is personal and affected by age & environment.

@wtp6128 Год назад

2A3

@DT-yt2zh 9 месяцев назад

300B has more bass. I like the sound better, but I can't say if that's just because I like bass. Which one would sound like a bass if you were in person? RU-vid compresses everything, so I'm sure I'm missing some of the other nuances.

@VirtualHiFi 9 месяцев назад

@user-fz2tl4of1v 5 месяцев назад

1st song - 300B has more bottom end, 2nd and 3rd songs - 2A3 has more clear mids (300B sounds like some ''small room reverberation'' at about 1 kHz), 4th - 2A3 low end is poor and sound is "compressed" (may be lack of power?) on violins again 300B has some more dynamics, tonaly don`t hear difference. I choose 300B)) sound`s bigger and not so strict

I don't think this is a fair test. Sovtek don't make very good 2A3 tubes, haven't heard their 300Bs. Any power pentode wired as triode sound better than 2A3 Sovtek. I have a stack of those Sovtek 2A3 collecting dust.
