Bitstream if you want the receiver to do the decoding, and PCM if you want the player to do it.
Bitstream if you want the receiver to do the decoding, and PCM if you want the player to do it.
I have an issue with this point myself.
The PS3, (I am told) does not have the chip that can process in bitstream the full sound information off a Blue Ray disc. To do this it has to be via HDMI.
Now to my ears on my system the soundtrack is much better (greater impact/presence etc ) via bitstream, with the 875 doing the processing.
I would try both ways and decide which you prefer.

Which Blu-Ray player and which AV amplifier do you have? Depending on the models, the Blu-Ray may not decode all the HD formats onboard or the amp may not be able to do this etc. which would determine the optimum settings.
But what if you have a disc with 2 soundtrack options; DTS HD 5.1 and uncompressed PCM 5.1? If you have your player set to bitstream, which soundtrack would you select?

Except bitstreaming via HDMI from a PS3 you're only getting the standard definition soundtracks - ie DD/DTS 5.1 - and not the HD versions.
With this setting you'll only get HD audio if you've selected the movie's uncompressed PCM soundtrack, where one is offered.

Assuming the DTS HD Master Audio track was taken from the same master, the theory says they will both be the same. Experience so far has led me to believe the PCM soundtrack is ever so slightly better. But there isn't a lot in it. Now if they haven't been taken from the same master, it's a whole different kettle of fish.

Hi Michael,

I had the centre speaker by wired from new, so cannot compare. But in the past have done so on my stereo systems, and find an improvement to the musicality, not great, but enough to be pleased with the by wiring.
Do so as a matter of course nowadays. Have all my fronts by wired as well as the left and right by amped with Kimber 4TC to the mids and QED SA everywhere else in the system.
