Excellent meet, can find detailed impressions on my site (link in my signature) but on a high level:
Hifiman Edition 6
Boy this was disappointing. Exaggerated midbass and lower mids, exaggerated treble, and terrible clarity that made everything sound distant. Also just sounded extremely compressed to me, not a fan, hoping part of the fault lies with the new EF1000 they had it hooked up to, would have loved to try this on my setup.
MDR-Z1R
If Sony's intention was to try to achieve stat sound with a dynamic driver, I think they did it. As fast and clear as some of the electrostats I've heard, and missing some of that dynamics, the physical impact and texture that I really love.
Inspire IHA-1
This little tube amp was a treat, which I could have heard it from something outputting a real line level source (I never got around to trying it with the TT), but this had that great out of head staging, great dynamics in the mids and treble wtih slightly soft bass. Made for an excellent listen, great when paired with my ZMF Eikon.
Eddie Current Balancing Act
Hooked up to the Ygg, this was one of the best setups of the meet IMO. Sounded fastastic, the imaging and separation of instruments on this setup was something to behold. A little glare in the top end, maybe from the lack of warm up, but still the technicalities of this setup really shone through.
Thanks again to Lee for organizing this so graciously and a pleasure to meet all of you, I certainly hope to be back again for another one of these!
