where to take the optical connection from to my AV amp?
I have a fairly new Sony Bravia TV plus humax freesat box and Sony Bluray player. All are connected via HDMI. I have a new AV receiver with a single optical input. Baring in mind all components are connected digitally is it best to take the optical output from the TV or the other devices?
I assume that audio is transfered digitally via HDMI and thus stays digital within the TV before coming back out the optical port and as such this would be the best place to connect to the AV receiver. I mostly watch TV via freesat and films via the Bluray player.
Also I'm sure this has been asked before: I've been listening quite happily via a standard analog phono connection to my amp and wonder if there really is that much difference in sound quality between good old analog and the optical digital output?
All help and advise greatly received.
