In Reply to: Help with Cable Box Optical or TV Optical Connection to my DAC posted by howgeif on April 18, 2016 at 10:45:44:
I assume you already have the cable box and Blu-Ray player configured to downmix surround sound to stereo PCM. Further, I assume they will also send downmixed stereo PCM audio via the HDMI connection.
Without knowing anything about the TV, it's impossible to say whether the TV will simply pass on the stereo PCM audio received from the cable box and Blu-Ray player without any additional processing or downsampling.
Another option might be to do the downmixing in the TV, but I couldn't say whether it would be better, worse, or equivalent to doing it in the cable box and Blu-Ray player.
So there's a lot of unknowns.
Assuming for a moment that the system can be configured such that the TV's digital output is bit-equivalent to what you have now, the decision should come down to whether you prefer the sound of the Ayre or MF DAC.
If the TV is not bit-transparent, you could always get an A/V pre-pro.
Regarding optical vs. coax, it's system dependent. In theory, a good coax implementation can provide better SPDIF signal integrity than optical, but an optical connection can isolate the audio signal grounds of the DAC and amp from the A/V side.
