Hi Folks here is my impressions of the 3 amps after playing around with them each for 200+ hours
We got A01 T01 and E02
All 3 offers very different taste desire and approach to the music presentation, if you get bored with one you can insta swap and feel a very distinctive change in sound and enjoy the new style.
For me its not necessary to own all the amps and you can simply pick one and sell the others but its up to you how you like collecting your audio gear...
From long listening sessions and during all the time I had all 3 of them I always came back to T01 it simply offers the most unique sound timbres and tonality. Very organic feel most of the time very airy. I do find it appeals to my taste the most and also the closest sound to my moded wm1z/Romi!
Ok here we go we start with A01,
This amp has a silk flavor of the AKM dac and yes you can feel its presence, its very smooth and the most gentle and less fatiguing among all the 3 I have. I find it has to much thickness and warmth it kinda suffocates the natural feel of the music and sounds like its taming to much the high frequencies get to much like a thick layer on top everything...
This Amp has a forgiving approach to the songs so less quality resolution tracks wont be penalized as much.
The vocals on here are slightly tamed down and have a laid back feel to them, it also dont have the clearness and resolution of T01 or E02.
This amp has a constant thick feel to the music, its lush warm across the board.
The bass is not as deep or rumbly its more linear and dont get that massive.
Treble here never get piercing, it can get high but cant never be painful.
This amp has barely audible hiss very quiet
T01
In this amp right away you get the feel of a more massive sound cleaner clearer more resolution and music feels more open and natural.
Bass is very deep and rumbly ripley at some point I wonder who is the deepest T01 or E02? I favor T01 over all others because the timbral resonance of sound waves are very organic and has a nice rare feel to it reminds me my bg caps hehe on my 1z/romi.
Definitely I feel better sens of imaging and sound stage on T01, E02 is also very close and maybe equal for that.
The treble on T01 can be fatiguing in the long run and is less forgiving for lower resolution tracks. Though it offers a nice emotional feel to the music as its slightly sharper in treble and deeper in bass. To me it drives your emotions and tickles them more offten due to that.
Overall I find T01 to be very good and close to life like musical perception. But I think E02 wins for the closest life like experience for music.
T0 has an addictive very authoritive sound, its clean clear, massive and very very nice airy feel to the music with awesome sound stage and resolution!
I like this amp the most and its my favorite.
Vocals here feels more forward then a01, but with higher treble we can get the Thshhh and ssss more prone to emerge and be felt slightly siblant. That depends on your headphones I guess to what degree it will be pronounced.
This amp has barely audible hiss very quiet
E02
This amp feels the most accurate and life like sound, more then others in this segment. Very close to T01 and a step above... It has clearer and less thick sound vs T01, which I find brings in the higher resolution and clarity.
Voices here are very admirable and pleasant cant find anything to reproach. E02 has the best vocals performance for sure. It just feels very natural and timbers are not thick or bright. This amp has the best balanced between all frequencies, very audiophile like tuning with a fun factor.
Treble on this amp is less sharp then T01 and has a better sense as they closing to that perception being more natural vs T01. Even if its less sharp it still has the great control and detail accuracy in treble. This amp is probably the most details and layered among the 3 I guess the ess sabre shows its strenght here.
I find the bass less deep then T01 maybe its the organic vibrancies of t01 that creates this effect?
Overall I find E02 a good step up in technical performance over all other amps but I still prefer T01 for its warmer and more organic feel...
E02 is very accurate detailed and precise amp, you want the best performance and nice darker feel to the music this it the one!
I have 1 serious issue about E02 its not like its a deal breaker but almost there... Its the hiss! T01 and A01 is very very quiet I never hear the hiss and it never bothering me at all! But with E02 I can get the hiss heard in low quiet passages of the music, so yea if not that it would be a big winner!
Also that squalshy strange radio frequencies type hiss, I saw a few had it also here. For me its weird sometimes I hear it sometimes I dont, its an intermittent noise. But I never hear it while I listen to music its quiet, its rare when I will hear that squalsh and only when the music is in a quiet dead passage for more then 4 seconds... Also when Iset play and bring volume to 0 to purposely hear the hiss lvl for test...
Here was a short and detailed overview of the 3 amps, I highly highly rec the T01 second would be E02 then others
