I have just connected my sky box through the component loop through of my Denon 2805. I'm pretty sure I can now see lip sync problems which weren't there when going direct to my panasonic PHD8 plasma previously. I have a lip sync correction option but it not active on stereo or direct which is a little frustrating. Could the amp really be introducing audio delay or have I seen it because I'm loooking for problems with the new connection method?
