Well, I picked up the Adcom GFA-555 last night. The guy who sold it to me was real nice. There was not a scratch on it! This thing looks as if it just came out of the show room. Got it for $300.
He said that using high quality speaker wire really made a difference. He had this eight strand speaker wire that he was using. It looked like 8 individual 18 gauge wires - 4 for positve, 4 for negative - bundled together.
I'm going to hook the whole thing up this weekend and fast forward to the flute and flugelhorn solo in Sparkling in the Sand by Tower of Power. That's a good test of highs and lows.
Am I really going to need a separate sub-woofer? Also, how would I hook that up as there are only left and right speaker outputs on the Adcom?
