Well, it's a mini-meet, but since I got to speak to folks and listen to a lot of cool gears, and did comparisons, I was able to get impressions on a lot of stuffs.
First up... Zana Deux + HD800 combo. Man, I was floored, no doubt. Easily the best system I heard at the meet. Everything was just right. Especially the midrange. It wasn't too bad for dubstep and EDM either.
Next... HD600 + Geek Out 1000. Haha... I never thought I would say this, but this is not half bad for a transportable setup (it's transportable because the HD600 is not a good choice on public transport... or airplane). For approximately $500, I think this can be end-game for a lot of people.
HD600 + Bottlehead Crack... legendary. Enough said.
HD800 + Bottlehead Crack... hmm... I think I prefer the Zana Deux for a bigger soundstage and slightly cleaner presentation, but... all things being equal, this is not a bad budget setup either.
Stax SR-007 Omega 2 Mk.II... wow... technically with warmth and smoothness. It's not the best setup out there, but it is still technically very competent compared to the rest of the other setups. If it was more spacious, it would have been killer.
Hifiman HE-500 + Schiit Lyr... nice BASS! Nice midrange! Soundstage a little congested, but nothing too serious. I think that's due to the clamping force more than anything else. Easily one of the best setups there. By the way... this is still not enough volume for the HE-500! Mwahahaha!
Svetlana 2 + ATH-W3000ANV... hmmmmmmmm... weird sound where it's both spacious and super warm at the same time. But not "oh man, this sounds bad!" kind of weird, but the "oh man, this is surprisingly good!" kind of weird. Love the impedance switch. Wish I had my measurement tools there to see what sort of effect it has on the output impedance.
Svetlana 2 + ATH-W1000 (non-X)... this one is stock. It's not my pair. My pair sounds... very different. That said, this one has a pretty nice full sound. It might be a bit dark, but not as excessively warm as the W3000ANV. Overall it's a nice relaxed sound with some body. But... it is still very different compared to my modded pair!
Leckerton UHA-6S Mk.II with AD4627 + UERM... wow... it's scary how even and technical this combo is. It's just... good. There is nothing to complain. Enough bass, midrange, treble for everyone, I think.
iMod + Pico Slim... oh ho ho, here is a surprise. An unexpectedly fun setup. Pairs very well with UERM. I can see how this can be one of the ultimate portable rigs.
Now this might be a shameless plug but...
HD600 + McIntosh Mac 4100... anyone who owns a HD600 must simply hear this setup at least once in their audiophile career. Seriously. I insist!
Those are fast impressions from my memory.
Thanks, guys, for making today possible! I had fun, and I also had a lot of good feedbacks on my modded headphone to know which direction to head toward.
