Apparently that Carver amp is a very popular item. One in mint condition just sold on ebay for $430 with 42 bids on it. There are lots of great power amps on ebay for lots less that will greatly outperform the Cambridge Audio, IMHO.
Carver TFM 45 or Cambridge Azur 851A
I'm finally getting around to the 21st century. I just purchased a Cambridge 851N. I was planning on ditching my Carver pre-Amp and connecting the 851 directly into my old Carver TFM-45. I then realized maybe I should get a new preamp and looked at the 851E. Apparently that pre-amp is now discontinued. Cambridge sells their 851A integrated amp for $1,499 which is within my budget. So I guess the question is this sonically... am I wasting my money on a new amp? Or is the Carver a boat anchor?
