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!

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.

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.

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.

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

@dannyalvens5418 5 ай бұрын

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...

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.

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.

@gjnbouwmeester5860 Жыл бұрын

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!!

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.

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.

If me the music was very nice, but without each tube playing the same piece I think to be difficult to ascertain the nuances.
