Need a little help. I am looking at 2 amps to upgrade my sytem with . One is a local sale for a Carver TFM55x and the other is a Parsound HCA-1500 that would be about the same price.I know the carver haves higher power output. I have not personally listened to a Parasound amps but I see nothing but good reviews . They seem to be somewhat larger and run warmer so I know I would have to give it space. Can anyone give me your 2 cents regarding which one is a better amp? Which would you buy?
