Thanks - yes the S-A2000, A2100, and A3000 all look similar and seem to have a similar quality construction. A lot of little improvements. But the stats are different at 90w and .07 THD more than 10 times worse. Maybe they measure things differently these days, I don't know. I wouldn't want anything less detailed than the mx-2000 - my priorities are detail first, soundstage second, and not too cold. From what I've read so far, the reviews are mixed, some with reliability concerns, although the sound signature as reported by many resembles the mx-2000. Steve Huff thought the A3000 was one of the greatest amps he heard - until it broke on him. Maybe Yamaha has lost the mojo of the late 1980's. A lot of great audio came from that period, including the R10 headphones from sony.
I'll probably keep the mx-2000 for a while, but I'll start looking around. Are there any non-Yamaha amps that sound similar for under $2500?
