My wharfedale diamond 9.1 speakers right now are connected to a old school marantz reciever my friend loaned me. It is failing I think though, so I am going to replace it probably with this http://nadelectronics.com …ereo-Integrated-Amplifier
The NAD C320BEE is a nice integrated amp, which competes pretty closely with the Marantz PM7200 that I have. I belive that the NAD is about $50 US cheaper. Both sound great, although slightly different, and I only chose the Marantz because it comes with Class A (minor benefit) and a preamp for my turntable (significant benefit). If I didn't use a turntable the choice would have been tougher, but frankly either one gives incredible performance for the price.
