Adcom GFA-555se

Bridgeable Power Amplifier

The ADCOM-USA GFA-555 represents the most advanced thinking in audio amplifier design. It offers exceptional value and superior performance at a reasonable price.
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.

Sound Delivery

We have worked long and hard to ensure that the GFA-555se power amplifier improves upon its 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.
