ADCOM GFA-555ms Stereo Power Amplifier with Bridged Mode - New in Box.

Bought to run a Subwoofer that I wanted to build, but decided not to build the Subwoofer.

Retails for approximately $1300.00 including taxes.


Open Box for viewing.

GFA-555ms runs on 200 W into 4 ohms, takes both Unbalanced and Balanced inputs and drives your speakers with 40+40 Watts of high performance, ultra low distortion power output all from a neat package. We have engineered an uncompromised circuit design that delivers ultra-low distortion and a crisp dynamic sound. It all adds up to a startlingly vivid and highly impactful musical performance that will put more energy into your loudspeakers as well as control them like never before.


Great care was taken to insure that distortion in the amplifier
would remain extremely low, particularly when driving these highly reactive loads
in which the phase angles of the voltageand the current are substantially different.
