I've had a Yamaha as3000 in my system for two days now and it's a pretty amazing integrated. Was aiming for a 2100 but couldn't resist the 3000 and bought it used. It's doing the things MOSFET's are good at (smooth, liquid, natural) without some of the nasty stuff like lack of detail or energy. It has a big, powerful, detailed sound but I do find that I'm listening a little louder than I typically do. Using it single ended right now but will soon try balanced. Looks aren't supposed to matter but it looks awesome in silver. Built like a battleship. Very happy thus far.
