Sumo Andromeda Class A/AB High-Current Stereo Power Amplifier (1982)

Sumo's class AB Andromeda features a full-wave, four-quadrant balanced topology providing total control over any loudspeaker connected to it, regardless of load type. It's four independent push-pull feedback loops maintain your speakers in absolute phase with the musical signal, resulting in perfect imaging and a wide soundstage. Andromeda achieves its astonishing accuracy through a combination of high power output - 200 watts per channel into 8 ohms and up to 350 watts into 4 ohms, and a complete lack of current limiting. Rather than introduce invasive circuitry to protect the amplifier, which results in restricted dynamic range and increased distortion, Sumo engineers installed extremely wideband, high-dissipation power transistors at the output. The dynamic range and awesome deep bass response of Andromeda are unapproached by any other amplifier. This item has been tested and is fully functional.
