This amplifier when working delivers good sound. However, you have to get a good one and not one that was made before dry joints. I have said it is good quality because it is made well and of excellent construction. The reader may think I am confused, but my sample was damaged by the courier and I am unable to say what two channels sounded like. The one that did work was a good solid detailed sound.
These amps were generally sold as part of a "separates" set up in the 1980's. They have any amount of inputs - Phono; CD; Tape; Aux; Mic. etc, and on the output side accommodate almost any decent speakers. The amp also has 2 extra buttons - one for Surround Sound and one for Super Bass. The Surround Sound button works really well with even 2 speakers.
I'm using it with a matched Technics turntable and 2 x Wharfdale 9 bookshelf speakers. The sound is excellent, and there is no noise from the amp at all. Highly recommended - get one if you can before they disappear.
