Bridgeable High Current Power Amplifier
A CLASSIC REBORN AND ENHANCED!
The classic award winning amplifier design of the original GFA-555mkII has been reborn. The Adcom GFA-555 represents the most advanced thinking in audio amplifier design. It offers exceptional value and superior performance at a reasonable price.
GFA-555se power amplifier represents the pinnacle of ADCOM’s audio engineering. This Nelson Pass design broke ground when it came out in the 80’s, getting rave reviews and providing tank-like reliability at a decent price. That these amplifiers are much in demand after so much time is strong testament to their value and durability.
We have worked long and hard to ensure that the GFA-555se improves upon it’s original eminent version in key areas, delivering even better performance. Externally, the chassis footprint and front panel design are identical to the original. Internally, all circuitry has been upgraded to meet ETL/ETLc, FCC, LVD and CE/EMC requirements using UL approved FR-4 printed circuit boards. High performance component selections include ultra low ESR electrolytic capacitors. The result of these improvements is lower distortion, better dynamic range, improved damping factor and greater stability and separation of individual instruments on the sound stage.
