Classe CAP 150 vs CAP 151

Well....this is really not an answer to your question..but
it is going in the right direction. The original CAP-100
and CAP-150 were said to be the same...except for output
transistors. The CAP-80 was rated at 100 watts..like the
CAP-100, but had a digital volume control, where the CAP-100
and CAP-150 have a remote operated via motor-drive Vishay
volume control. From what I have heard the CAP-150 and
CAP-151 are the same except for the faceplate..and (and I'm
not sure on this one) the CAP-151 may have a volume control
like the CAP-80. Some think that the CAP-80 is the sweetest
sounding of the bunch..some the CAP-100...but the CAP-150
and CAP-151 seem to have higher owner ratings on
AudioReview? Hope this helps.

Thanks for the resonse. I believe you are correct. One difference between the CAP 150 and 151 is the 150 has a balance control and the 151 does not. There might be other differences and maybe someone else can comment? I would like to hear from someone who has compared the Classe with the Plinius or the Sim integrated amps?
