The Onkyo A-9555 should be a good choice. The link is to a Stereophile review. I've owned one and was very impressed by the sound and the build quality, though I didn't try the phono stage. List price is $800 but they're generally available around your $500 limit.
50 WPCish Integrated/Receiver for Apartment
Any suggestions for a really good 2 channel receiver or integrated amp for running a pair of Klipsch Quartets in an apartment? Something with a phono input is preferable. Looking to spend less than $500 and have looked at the Yamaha RX-397 receiver. Has anyone spent any time with this unit and/or have an opinion on it? Listening to a wide variety of music, 60s and 70s rock being in the slight majority.
