Hmmm...I wonder why Malcolm isn't using HDMI then. Seems like a no-brainer, and that Oppo would have told him to do that (instead of just "wait for the firmware"). I'd assumed the obvious thing was HDMI from box to 105; then HDMI to TV for video, and "regular" (analog) interconnects to integrated amp for audio. Is anyone certain this will work? If it does - and there are no "out of sync" issues - the sound would presumably be better than the cable box or TV audio to integrated amp.
The main thing I had wondered about is whether it's really worth it, i.e., is the cable sound already so compromised that it makes little difference that the 105 is doing the D/A conversion instead of the box or TV. I'm willing to try it if there are no sync issues. If there are, though, I'm not interested until they are cleared up.
