Just got mine last night from the post office (although I suspect it arrived there last Friday). It somehow managed to get past customs without me paying anything extra (maybe because it was a small package). The only thing that I was slightly disappointed about was that I needed a plug adapter (and good thing I had a universal one lying around), but then again whole Europe uses different plugs, so can't really cater to everyone.
Sound wise it is excellent at first listen, although I haven't put more than 2 hours worth of listening to it. My setup is a Thaulab Varna IV > DIY Belden cable with Neutrik Rean RCA plugs > O2 > Sennheiser HD-555. First impression is that it's dead quiet (or if it's noisy, it's imperceivable to me). Sound is just something else (in the good sense) - compared to the headphone out of the DAC, it's quieter (the headphone out has a weird ring/hum), the sound is way, way more dynamic, the bass, even while not a strong suit of these headphones, is now tighter and moving easier, toms and cymbals sound way more articulate, vocals are more forward and everything is just better. I haven't yet listened to quieter recordings, but normal sounding ones didn't require me to go past 11 o'clock on the knob at 1x gain, so there's plenty of loudness (although I'm usually listening relatively quietly). Channel imbalance is there, but it's below comfortable listening levels, so it doesn't bother me.
Overall I'm very happy with it at first and I hope my impressions stay the same with more time. Can't wait to get home and put some more listening to it.

killchainHey, maybe you can help me. Where are you from? I ordered the 220V plug, thinking that it would work in germany, but I got a 240VAC 60hz with the wrong plug. A plug adapter would be easy to get I guess, but 60hz doesn't work in germany. What kind of adapter did you use? Did you buy a whole new ac adapter or just a plug converter? If you bought a whole new ac adapter, could you let me know which one?
Thanks!

killchainHey there. It came with this power adaptor - http://imgur.com/LFY38eO - it has an ungrounded NEMA 5 plug if I'm not mistaken. I had this plug converter lying around - http://imgur.com/e8Ayggv, http://imgur.com/vZkzGSe - it's basically several-things-to-Schuko. The mains is 230 V / 50 Hz and everything is fine. No hum/noise or whatever. The only noise the amp is making is a light crackle when turning it on and a bassy pop when turning off. From what I've read (nwavguy's blog) it's safe for the headphones.
