What do you listen to music with?

I have an old NAD 314 amplifier (2x35W @ 8ohms) and a pair of Dali 6006 floorstanding speakers. My CD player is a Philips CDR765, same as I use for mastering my music. I'm thinking about getting a surround receiver, but I need to find a good one.

I also have a pair of Sennheiser HD280Pro headphones.
