I have here a pair of Dusty's 40w chip amp monoblocks in great condition. I used these very happily in my system for quite some time, but they've been sitting idle since I picked up one of Roger Modjeski's EM7 SET amps. I love both of the amps, and have been entertaining the fantasy of keeping both - but reality eventually sets in, and I have to make the choice.
It wasn't an easy choice, either. The VMB1s have a lot going for them. They are very sensitive, and reach full output on a tiny little signal. So don't bother trying to match these with a high-gain pre-amp. They are extremely dynamic, though. One of the areas in which they trump my SET amp is in the intensity with which they deliver music at very low volumes.
I had these monoblocks paired with a sweet little, low-gain, 6sn7 based pre-amp, and the music never failed to get my feet tapping.
Them VMB1s are not in production any more. You can find out more about them here:

I'd like to get $525 for the amps, plus shipping (from zip code 48103) and any paypal fees. But I'll guarantee you won't have to part with any more than $550 for the lot (less, if shipping is cheap). I have the original packing material, which is really and truly excellent. I think each monoblock gets encased in some heavy-duty styrofoam stuff that's almost 6" thick.
