Weaknesses of the Adcom GFA-5802 ?

Having purchased a GFA 5802 along with the matching GFP 750 and GCD 750 when they first came out, I can tell you that the preamp was the star of the show by a long shot. The GFA 5802 although not bright, is a bit of a grainy sounding amp with very average bass and does not provide the kind of headroom you would expect with its stated power output. I feel there is much better sounding out there at that price in the used market.

Thank you Chris74. This is exactly what I was fishing for. It's looking like what I need, and what I can afford are two different things ... LOL

Well I owned a GFA-5800 which was I think the same design but with fans for cooling.

The bass was phenominal. Bascom King did the review of that amp and loved it saying it bettered amps selling many times it's price and he especailly liked the bass calling it Krell-like. There was nothing wrong with the headroom. I wouldn't call it grainy either, misty maybe, and that was it's main failing -- the highs were not the best.

I sold it and replaced it with a Threshold S/550e because I didn't like the fans and i've missed it on my subs ever since.

Hi have to agree with Chris74...many moons ago I had an Acurus A200...thought I was upgrading to the Adcom 5802...boy, was I wrong. The Acurus outperformed it in every way and it was half the cost. Goodluck!
