Wanting Coax rca digital out on DVR, Streaming

So many options and devices!

I have an EAD Theatermaster Ovation Plus, upgraded with a few things. Sounds with RCA digital inputs as a DAC.

Is there a TIVO with RCA digital out?

There's a big difference in audio quality with my Wireworld glass toslink cable vs. rca cables (rca is better).

Am I forced to use toslink? If so, are there any toslink cables that can approach a high end rca digital cable?
I have the DH Labs toslink and it beats everyother one in that price range hands down - use it for streaming WAV to my DAC - it had the highest bandwidth and made the music sound so much better - I would guess due to fewer dropped bits
