Violectric, audio gd, schiit, O2. I know I know, not quite reference... I've edited my post not to sound too praisy. I've sold mine because I am moving and getting rid of audio things atm, so I like to think I'm not THAT biased. However it's my subjective opinion, and it might ofc not hold up to universal standards.

Also if I remember correctly you guys tested it at a meet with not your personal best DACs. I don't think you would have changed your minds, but it would have been interesting to see how you think the sound changed. IMO this is a very DAC sensitive amp.

Pretty much inline with my experience as well. We've heard it a few times. It's fine if people like it but seriously there is nothing totl about its sound. I suppose I'd call it an improved Yulong sound which isn't saying much. I think the Bakoon slays it and I'd consider that midling performance/sonics. But that's just my frame of ref.
