I currently have a 5.1 setup with a Yamaha receiver, 2 front Infinity RS-3 speakers, 2 back Infinity RS-3, and one center Infinity CC-3. Its all great but the receiver has died (center channel output won't work) and I am considering either replacing it with an Onkyo NR509 receiver or buying something more compact and getting rid of the 5.1 setup. I use the setup for watching TV, movies and listening to music. I would like to go as compact as possible as I live in an apt and the large speakers and wires all over look unsightly. I know that a small system may not sound as good but I am willing to compromise. The main thing I see myself missing is surround sound. Ideally I'd like just one unit, but if I do have surrounds would be great if they are small and/or wireless. Any suggestions welcome.
