I used to own a 100.2 amp myself. I like it very much. It was a sleeper in the Audio Research line (the Audio Research tubes amps got all the attention). I got a good deal on a Berning ZH 270 and the rest is history. The ZH 270 is truly world class!
Audio Research 100.2 amp
Why didn't this amp receive more attention when it was in production? I recently acquired a pre-owned 100.2 for my second system and was very impressed with it's performance. Much more pleasant sounding than many other solid state amps I have listened to with a very nice, grain/grunge free, almost tube-like midrange and excellent bass/treble. Musical, smooth, resolving without sounding etched or aggressive is a very good way to describe the overall sound of this amp. Anyone else cares to agree/disagree?
