I'm apparently on Zilch0md DST as well.. just past 1:45am here in the lovely pacific NW.. and I got the Millenia all hooked up.
Rig? Izmo M1 (USB to SPDIF) > Violectric V800 > TBI Millenia > resistor box > Sennheiser HD800.
The Millenia is running off AC.. it's power supply brick (as well as the V800) is connected to the outlet with one of those fancy, big time 'audiophile' power cables *ducks*
A couple of things about the amp itself.. build quality is terrific. It's got a weight to it that makes it feel substantial. I love the all black look.. sleek & understated. As Mike said, you reall don't appreciate how small/compact this thing is until you see it in person. One caveat.. even with the resistor box, there's some low level hiss w/ the (fairly sensitive) HD800.
The sound? I'll sum it up with this:
It's disgustingly good. This diminutive box has NO BUSINESS sounding this good. I'm impressed.
What jumped out at me first? The transparency. To my ears, the Millenia sounds extremely clear and doesn't really add any kind of its own 'coloration' to the sound. It might tilt ever-so-slightly to the 'bright' side of neutral.. but the HD800 itself is slightly bright, so it's probably the amp 'getting out of the way' and letting the HD800 shine through.
The amp's tuning feels very linear.. bass is very taut, clean. I'd like a little more impact.. but we'll see if that aspect improves with use (as the amp breaks in, etc). Make no mistake about it: the midrange is a show stealer. Articulate, impossibly clear, utterly effortless, impeccably detailed, airy, and liquid smooth. Going back to the point about transparency, I don't find the mids particularly lush, warm, or colored.. just very clear and detailed. The purity of the timbre, vocals in particular, is stunning. Pianos, guitars, saxes.. everything.. it sounds incredibly natural, vibrant, and dynamic. Treble was one area I was concerned with.. worrying if this amp might be too warm or rolled off. Upon hearing the Millenia.. those fears were immediately allayed. The treble is airy, open, and, again, very accurate. There's high degree of resolution in this region sounds realistic.. not like it was carved out of stone.. or dissected in a lab. If you're looking brutal, clinical, sterile, exacting treble.. you won't find it in the Millenia. There's a slight peak in the upper mids/lower treble.. but again, that's more in line with the HD800's tuning than the Millenia 'adding' or 'emphasizing' a particular freq. Again, we'll see how this goes as the amp gets use.
I'll close out these initial impressions with (another) one of the most impressive aspects of this amp: the soundstage & imaging. It's absolutely wonderful. It's spacious, immersive.. but precise. Instruments are layered and spatially placed in a very natural, realistic manner... mimicking a live experience with frightening accuracy. In terms of listener placement.. I feel seated three or four rows from the stage. I know that's such a vague rubric.. but what I want you to take away from that is that the sound isn't overly intimate (as if you were on stage, surrounded by the band).. but you're not positioned uncomfortably far from the stage where the music sounds like it's coming from some annoyingly distant locale. IME so far, the space between the band and the listener is perfect in terms of being able to accurately gauge cues and not suffer from listener fatigue.
I'm not going to go into minute technical details right now cause I want to spend more time with this amp. It took me an hour to get this blurb typed up.. cause I found myself compelled to step away from the keyboard and just listen. If first impressions are important to you (like they are to me).. this amp certainly feels like it's something special.
