>>taking the digital COAX audio output into her Stello DAC then off to her Manley Stingray, - two channel. <<

So, let's talk about this. AFAIK, the Stello does not decode Dolby Digital or DTS, so you will need to set the player to downmix Dolby Digital/DTS 5.1 to PCM. When you do this on a standard commercial DVD or Blu-ray, the output is limited to 16/48k PCM.

So, it's lossy DD or DTS, downmixed to mid-res PCM. It's basically about as craptacular as you can get. You're then feeding it via a digital interconnect into a DAC, which converts it to analog, then sends it via interconnects to the Stingray's preamp section. Nothing untoward about this other than it's several points for crappy audio to be made crappier. You also have the opportunity to introduce lip-sync delay because of all that stuff in the middle, and the Stello won't allow you to correct for it.

I suggest that it would be better to bypass the Stello DAC - it's not going to help the situation. Instead, let the player do the D/A conversion, and output 2ch analog from the player directly to the Stingray.
