I have a pair of nice mid eighties Cornwalls that I rebuilt last year. They have new crossovers, new 15" drivers and ct-125s all from Bob C. I am looking to buy a nice 2 channel amp that would match up with these. This is my second pair of Cornwalls. I had a pair in the late seventies matched up with a Nakamichi 610/620 combo. I liked them alot. Can someone give me some advice on some nice sounding amps for these. I know a lot of people would advise tubes,maybe I should...thanks in advance....Randy (PS if anyone has a 610/620 for sale i'm interested)
