My father purchased this QX 8000a in the 70's and it is still kicking. The tone quality and balance of this receiver is amazing for low volume listening. I have it hooked up to some DCM Timepiece bookshelf speakers (older not ported model) I picked up at thrift shop for $20. I get as much enjoyment listening to this setup as my CJ/NYAL/Vienna Acoustics setup. Agree on pots being noisy and need to clean up volume before I destroy my speakers. I hope it keeps going for a while. My dad has since passed away. Thanks for the great receiver, dad.

Great sound and high power for a quad. Some of these pioneer's have volume pot problems so beware of that.

Very impressive quad receiver. Sounds clean and has plenty of power for a single room setup. However, don't look to this though if you want a monster receiver.
