What is your budget? Look on Ebay or Audiogon for the type of amp you want. Also look for some decent speakers. To a large extent the amp depends on what speakers your are going to drive with it. Any decent two channel amp will do since the sub is fed from the 950. I did something similar last year with a Sony surround receiver I had laying around. I paired it with some Advent speakers which had also been retired and a 100W KLH sub. I use it for playing my iPod and watching TV at my other home. As far as amps go I would steer towards Yamaha myself because I have always loved their two channel stuff. The older ones are built like tanks. I still have a 45w CA-800 from 1976 which is perfect for 2 channel except it is all manual with no remote anything.
