Very nice old set...mine is a little beat up but it is a great monitor amp in our classroom. Very solid 35 watts into our little JAMO monitors.

Nice budget receiver with a decent, warm sound.

This receiver is great for people who just want to play music in a small space like a bedroom or apartment.
