For best audio to a home cinema 5.1 (DTS/Dolby D. decoder) is it better to use HDMI or Mini Optical TOSLINK?
I'm no expert but I wouldn't have thought that it would make much difference as they are both digital signals. I would go with what is most convenient for your surround sound system, although obviously if you are using HDMI you will need a pass though system to your TV.
In my view best is often simplest, ergo HDMI as a one cable solution with pass through would be the obvious choice.
I know the Ninjas worked on a good DAC and wonder if that hard work will show only via Optical compare to HDMI.
For me the better is all via HDMI for sure.
I'm by no means an expert but I would assume Optical would be best since that's a direct connection.
HDMI better for syncing automatically. But in general since it's only 5.1, there is essentially no difference, especially if you are bit streaming to a receiver processor.
Thank you sounds like HDMI will be
