I can't speak on the wireless vs wired but I sent back my 500 for the 600. Granted my room is big but I couldn't hardly tell the 500 was there. The 600 was a massive increase in sound parked in the same location as the 500. I'm adding a second 600 in the near future as we are finally putting our theater room back together.
