Just to add more information on my problem... I was listening to a SACD in stereo outputting directly from an Oppo 95 to my headphone setup. I don't need the 5508 to do so but I turned it on so it could feed my second screen the video via component. Whenever I paused, skipped tracks, fast forward, etc the 5508 didn't click once. It did exactly as I would expect a processor to do. It stayed locked onto the signal regardless of when it was paused, fast forward, skipped track, whatever. It worked flawlessly. I tried it using the hdmi and balanced outputs of the 95. They both worked as they should with no clicking.
Which keeps me thinking the issue is my Verizon quantum box dropping the audio signal whenever the feed is interrupted. That won't explain the random split second drop out when listening to a show that doesn't change to a commercial. That is still a mystery. But it might help diagnose exactly what is going on. I really need someone here who has quantum and the 5508 to comment on this. Are you out there???
