Hello, I just picked up an old Sansui integrated amp. AU-317 50 watts/channel and built in the late 70s. Cost me $40. Not only is this thing built like a tank, it still sounds very good. Even better then my 1 year old Onkyo sr600 receiver. Smoother sound and tighter, more controlled bass. Just wondering how much I would have to spend to get the same sound out of a receiver.
