I plan I buying 4 Polk r150s, a CSR, and a VELODYNE VX-10C sub based on the recommendations of this forum. I use a ps3 for playback on a 720p projector. I was wondering if with the speakers I'm planning to buy, will I hear the difference from lossless audio in a onkyo SR-605 vs lossy in the SR-505? Right now I using computer speakers, with no surround sound, so I'm not able to tell if its worth it or not? Also is the VELODYNE VX-10C sub a good match with the speakers?
