I auditioned a Classe CA-100, CA-200, CAV-150 (own), Bryston 4BST, Krell, Audio Research, Krell, etc...with Aerial Acoustics 10ts + Lexicon. My opinions: The Classe CA-200 was, by far, the most musical amplifier. The midrange was as good as the Audio Research and very smooth and realistic. The highs were great. However, the bass was weak and the soundstage wasn't as crisp as the Bryston. So, if you want to do HT, get the Bryston. If you want to do music, get the Clasee -- but, whatever you do, do NOT underpower the Aerials. The CA-100 sounded horrible -- very compressed -- running on my 10Ts. You will notice that the caps on a CAV-75 are much smaller than those found on even a 100/150 watt CA amplifier. So, I could recommend CAV-150 bridged to 300 for center and surrounds and a CA-200,300,400 for fronts (8's) Best Regards, Happy Listening, Mark
