Just taken out of the box but boy I'm giddy. NOS on steroids. Sorry for the THX haters but ladder DAC pairs very well with low distortion technology of the THX, in my opinion. My dream set-up would be replacing it with an ECP Audio T4 but for now the THX does... well. Well enough to listen to some sweet music that's for sure. No digital glare to speak of, that's with the out of the box USB which has been tweaked from spring one (basically the major upgrade from spring I to spring II, better USB and much higher specced, lower latency too). Other than that, level 3 has some insane power filtering, this DAC has a damn great blackground going for it. From my 3-something hours impressions what can I say, it's still NOS. Especially at lower sample rate you will lose some treble sparkle in a trade for some more romantic sound benefits. Honestly I'm sure more people dislike raw NOS sound than those who love it. Since I'm in camp II though, I feel like this DAC is made for me.
