Description

Adcom GFA-555SE 200 Watt Stereo Amplifier

Description
The classic award winning amplifier design of the original GFA-555mkII has been reborn. 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, greater stability and separation of individual instruments on the soundstage.
