Connecting cable box RCA digital out...

What setting is your cable box using to output it's digital
signal. It's probably Dolby 5.1 and the Mytek doesn't like
that. You would need to go into the menu of the cable box
and see what settings are available.

wow woiked! thanks!

Mara:Did the sound improve dramatically???

Jfz LOL!
Mytek is JEWEL of audio indeed way better than it's priced!

Marakanetz: My question is does TV sound significantly better through the DAC vs going directly from the cable box to a preamp or integrated amp? I understand that a good DAC “should” sound better, but I’m wondering if it does in the real world, i.e., I imagine the sound coming in from the cable company is compromised enough that it may not make much of difference whether one goes directly from the cable box or from cable box to DAC to pre/integrated amp.

Thanks for any thoughts you have.

Yes it has a very good digital PCM signal even if connected to TV.
