This is an extremely nice James Bongiorno SUMO ANDROMEDA Mk II Amplifier. At 200 wpc it will power most any speaker with ease. I used it with a pair of German T+A Transmission Line speakers and the sound was incredible. They were produced in 1989 and are seldom seen on the used market. The Stereophile review of this amp can be found in June 1991 Vol. 14 issue 6. Don't let this one get away. Manual is available for free at www.davidsaudio.com.
Satisfaction absolutely guaranteed.
