Thanks, Chris- I forgot to check Butler's own site.

I've only had an hour or two to listen, but so far I'm very impressed. It really is nice to have some tubes back in the system. aa Tons of dimensionality, gobs of air and detail, it's pretty sweet. Moving into a smaller house here in Watertown forced me, sadly, to dismantle my dedicated 2CH rig, so while I'm left with just my HT rig it has to competantly perform double duty for music and HT. The weak link is being forced to use a receiver, but nothing else will really run my rig- I need the video upconversion and digital decoding modes to properly use my stuff, and comprehensive bass management for all sources. I'm aware of nothing out their under $4,000 that will do all I need, sadly. I've considered a McCormack MAP-1, but it doesn't do video or bass management. The Margules Daeleth has long intrigued me, but it's not easy to find a dealer. I saw one on Agon a few weeks back but it was sold before I had a chance to score it. It doesn't do video upconversion nor handle hdmi/dvi/component, but it does everything else I need.
Anyways, I can't say anything definative about the Butler til I use it for awhile, but it seems to be a wonderfully synergistic mate for my Monitor Audio Gold Reference speakers. Electrically it's dead silent, but I'm getting a little buzzing somewhere...it's faint but it's there. Could be grounding with something (I have a LOT of stuff plugged in), noise somewhere, a loopy transformer...tube microphonics? I'm not sure where it's coming from and it's too late tonite to monkey with it. Probably not a big deal. I'm used to tracking that crap down having so much wiring and cabling.
