If the TV gets its signal from a set-top box, then you could take the digital out from the box to the DAC.

 I do this via Coax SPDIF into my DIY DAC, and it sounds  better than direct Toslink from the TV, or via HDMI from the STB then back via Toslink from the TV. I also obtained a small but worthwhile improvement in SQ by connecting the "earth"/ 0 volts side of the SMPS powered STB to Mains Earth via a 10 ohm resistor .A direct connection as suggested by John Swenson didn't sound quite as good due to what appears to be a minor earth loop.


How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file.
