This amp is a hidden gem! It’s designed by Nelson Pass! So it runs hot due to the high bias point, 10 watts class A then class A/B 20 watts to clip. The only downfall is the cheap capacitors from the factory so plan on replacing the small supply capacitors.

I hooked this amp up to a set of Klipsch RF-7s (very efficient)popped in a cd and sheer enjoyment filled my ears. This amplifier exceeded all expectations, the Adcom GFA-5800 came to life from the delicate instramentals of Dire Straits Private Investigations to the demanding bass lines of Metallica's One, this amp shines bright. Warm and inviting is how I would decribe it, but what do you expect it's an Adcom, I'm sorry it's a Nelson Pass designed Adcom, even better.
The Adcom GFA 5800 is a top of the line amplifier.I would put this up against any amp costing thousands more.These are very underrated.They produce alot more power than what they are listed at.I have speakers that demand ALOT of power,and they have never been louder or sounded better than when hooked to the GFA 5800.You WONT find a better amplifier,not even if you spend $3,000 for one.
It has 250 watts per channel and it's a beast. It is a quality amplifier.
