In discussing this kit with my buddy DaveD, and mentioning it in numerous forum posts, it occurred to me that I'd probably not written a customer review, so while a couple of years late, here goes.
I've built a few kits and from scratch electronic projects over the years - including several Bottlehead tubed amps and pres, but this was easily the simplest of them all. As for the sound - quite possibly the most transparent amp I've ever (not?) heard, and with the right speaker the modestly rated power is more than enough for pleasant listening. No, it won't break the windows, but at a price far less than some golden-eared audiophools pay for power cords, it certainly won't break your bank account either.
Can't wait to see / hear what's next from the combination of talent that put this one together.
