The build quality of Adcom amps are always solid and this GFA 6000 5 channel amp is no different. Outside the unit presents itself very well with only a few small nicks on the bottom left of the faceplate. All the other sides look great with only minor if any scuffs. The amp has been fully tested where it performed as it should. The amp comes from its original owner on a trade, it has been well cared for as it shows in the pictures. We don't have the original box for the amp but it will be carefully packed as we do with all our gear.
