The Adcom GFA-555 Mk II is a stereo power amplifier that was built between 1990-1995. It is capable of producing 200 watts of power into 8 ohms. Its sound can be characterized as natural and non-fatiguing with a hefty amount of bass punch. In short, these amplifiers are an absolute joy to listen to and they can power nearly any speaker. I've also ran two of them as monoblocks in bridged mode and it is simply amazing.
This one is in great condition with some small blemishes throughout. Operationally, I have check it over inside and out and found no problems. It has been running every day for the past 7 days and it sounds great into my Aerial Acoustics speakers.
