Howdy, This thread is for an Adcom GFA-555 amplifier. This is a two-channel amp rated at 200wpc. It is a real power beast, but it has been relegated to operating my zone 2 speakers and I can't justify using this monster for that purpose. Plus, I need the money for my home theater habit (you know what I mean.... its an addiction). Anyway, this is the GFA-555 that is rack-mountable with handles and is in excellent cosmetic condition and perfect working order; you'd be hard pressed to find one that's better. I'm asking $400 plus shipping. BTW, if you'd like some feedback/background for me, feel free to check my eBay ID: burrelm.
