I've found some devices such as DirecTV and AT&T U-verse boxes have problem with lip sync if signal is pulled off the RCA jacks.Albert - OMG! I wonder how the heck this could be? I'll have to experiment. I have Comcast cable. Thank you for the warning.
Has anyone had this issue using optical audio out from TV (the only audio out from my TV is optical, which is why I was considering RCA out from cable box instead)? I could get a converter for around $100 to convert to analog, but only if lip sync issue does not appear. Though I'd rather not spend even more money if unecessary.
Also, ignoring the potential lip sync issue for the moment, any comments as to my analog solution (Dayton T-amp and Audioengine P4 or Wharfedale Diamond 9.0 speakers)? Better amp or speakers for $400 or less (see speaker requirements in original post)?
