Cable Box Digital 5.1 converted to Digital Stereo

However, I agree w Kal that you hit the point of diminishing returns pretty quickly on the audio in the cable feed.

Yeah, I can use the Cable analog outputs, but I thought with a digital output through my Dac I could obtain better sound.
I'll check with Comcast about the Xfinity one box. However, past experience tells me that will be a hassle getting through to someone that's knowledgable.

Ozzy, on the Xfinity box you need to go to the menu and select 2 channel audio (PCM). Run an optical cable from the Xfinity box to your PS Audio DA converter - less jitter with the optical. I run this way through my Oppo BD-105 with good results. Some of the cable Paladia concerts are really nice. You may decide to stay with 2 channel after you do this. Good luck

8snaces, Thanks, I believe I have already tried it and there was no change. But, I'll try it again. Thanks.

I did this before with TW Music Choice, it does not improve quality to any degree worth worrying about.
