I am looking to purchase 2 amps to use as monoblocks but can't audition the ones I am interested in because they are used and generally only available through the internet so would greatly appreciate it if anyone can tell me the following:
1. is Adcom a good quality brand. I am specifically looking at the GFA 555 or GFA 5500. One is MOSFET one is not.
2. as far as the other brands I am looking at the Carver TMF 45. For the other brands mentioned I am not sure which models are comparable to the Adcoms.
