One observation that stood out to me here...( Airist Audio )
I used my modded HD800 headphones as a "measuring tool" to judge equipment, and I found absoulute lack of any dac chip signature, such as "sabre" or AKM or even similar to my Yggy..
The trebles had solid resolution without any distinguishable harshness/glare or signature that I could find.
That was initial impression only as it was not ideal environment, but the room was not loud either so I could here it well.
Although I have no comment on the amp,
I could still make out above average depth of field that is not very common amoung solid state gear.
This is why I always prefer tubes.
So bottom line I was impressed
I was also impress and pleasantly surprised by the tiny wooo portable (WA8)tube amp, what a sweet achievement!
Hifiman HE-X was excellent but he needed to have extra to try on setup other than tiny portable.
And ZMF latest offerings where so good they were a bit shocking and hard to put down.
I must admit love the Ethers though, they have a fleshyness that I had to have.
Every table had something quite amazing gear setups to learn from, so I was not around my setup again to answer anything but internals of my "bling" amp are posted here in a "SuperMod" thread for mk6&8.
There was a special Total piece that I would have to vote for most definitely:
that "orange" one on bottom.
