I am still using an Adcom GFA 555 in my current home theatre system that i purchased new about 28 years ago. This amp has been incredible throughout the years without having any problems what so ever or needing circuitry upgrades. I also have 2 other Adcom GFA 555 II amps also pretty old still cranking out powerfully in system as well.
