Opinion on the GFA 5802

The GFA5802 is a very solid muscle amp with great build quality. I like it better than the GFA555MK II or the GFA5800 mainly because it has all the heatsink on the side and looks very sexy with the gold metal plate on front. Sonic wise it is also the best among three. Its hefty toroidal transformer and the huge storage capacitance make it a real bargain in used amp market(if you paid less than $700).

I will recommend you to get the Adcom GFP750 pre amp if you want to fully explore the GFA5802 potential.

Thanks Lec, although I had a GFA-545II, the 5802 is so much better in dynamics and sound better to my ear.

with the 5800 series. Adcom started using some real power supplies. they have great dynamics and can drive just about any speaker. with some simple mods they can really sign. The 555 was an OK amp designed to a price point, not in the same league as the 5800 series.
