khz question

[DutchBoy]

The way I have my setup right now is as a 3.1 system. My rears aren't set up yet (in an apt.) because of wall/distance issues, though I think I've found a way around that. Not your typical setup, but it should work. I digress...

Since I don't have all 5.1 set up, a lot of times when I'm using my receiver for audio I'll just use PCM (even though it's 2-channel) for obvious reasons, I guess. No need for discrete rear sound without speakers...

I typically use the PS3 settings given for that -- I think it automatically defaults to 2-channel, 48 khz unless I'm bad wrong.

I managed to snag a copy of my receiver manual from the web (it's a Pioneer, about 5-6 years old, I guess, if not older) to find its specs, and it will do PCM at 96khz as well.

Simple question: Will I notice any difference using 96 instead of 48 khz?
