I'm trying to grasp a good idea on what would be a step up from my HK635 in terms of amplification. I have read high and low, but found most amps (in my price range) have equal to or less quality amplification as my HK.
I'm looking for and multi channel amp for at least the front 3 speakers in my HT system, that would be a step up from the HK.
I have found one amp that peaks my interest, a used Adcom GFA 6000. The Adcom is in my price range (~$300-$400) and seems to be in good condition, it has 6 channels. The specs (in terms of wattage to Fr responce) seem to be a bit better than the HK and I have no problem going used. Almost my intire HT is made up of vintage and used.
But in all honesty, with the amount of cash I'm dealing with (WAF), I dont think I will find much that is better than the HK.
