Description :
The Adcom GFA 5800, a stereo power amplifier. It sounds neutral and clean. This amplifier is powerful enough to drive any 4 ohm speakers with ease. The soundstage was wider, more precise and more coherent. This amp gave a new sense of pace, snap and rhythm to my music as well as presenting a deeper soundstage with well-recorded music (such as Reference Recordings Pomp and Pipes).
