I've my SR7300 for a couple of weeks. I don't have the delay in audio problem, but I do have a delay in LFE. I found this out when I was calibrating my speakers SPL with Video Essential test disc & Radio Shack SPL. When it's time to calibrate the subwoofer, I don't hear any LFE for about 5 secs. On my previous Yamaha RXV800, immediately I can hear the LFE on the beginning of the LFE track. Any comments from SR7300 owner?
