I love my 970. Had it for several months and (knock on wood) zero issues. I also did not know that about the "Switch". Thank Gonk! I just hooked up a SACD player to the 7.1 analog inputs and just left it in bypass without testing how it sounded in other modes. But I probably wont mess with it is sounds superb in bypass. When I was setting up the SACD I was not sure if I should set with PCM or DTS. I could not tell the difference in sound quality. I left in in DTS. I am not an audiphile. more like audiophlie.
