Using Oppo 105 for Audio from Cable Box?

I get the best sound by using the direct digital out from the cable box - digital rca patch - Krell Dac - CJ Preamp. It sounds as good as any other digital source in my system. You want to get your digital signal to your best dac, which in your case is clearly the Oppo 105. I think you will be very happy with this arrangement.

I have the Output from my Comcast cable box going into the coaxial input of my Oppo 105, and the video directly to the TV. It sounds good and works fine apart from one thing - the audio and video are out of sync. Strangely, the delay seems to vary, but at it's worst it is pretty noticeable. Oppo say they are going to address this in the next firmware release, but I thought i would give you a heads up.

Thank you, Malcolm. Very much appreciated.

Also: I was assuming one could go from the cable box to the 105 via HDMI. I guess not, huh?

Of course, you can go directly from the box via HDMI and that would be the best way.

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.
