96/24 Audio,DTS Signals

If your receiver processes all signals digitally, the answer is probably no. I bought a $2000 Rotel 985 about one year ago and it processes all inputs (except the 5.1) digitally as 48/24. For example, the signal from my turntable gets processed digitally as 48/24. It does this to operate bass management, balance, input volume levels, etc. I use the 5.1 input for my SACD player, but I lose bass management and other things (can't use the sub, DPL, balance). I can use the volume control.

If your receiver keeps the signal in analog (except when using DD or DTS), then it's likely processing near full resolution.

I'm not positive, but I don't your Yamaha passes a true 24/96 signal either. Pioneer DVD players are some of the few that do. Although maybe your Yamaha is newer?? I'm not familiar with that player.
