Don't confuse output levels with "more dynamic"! Listening to both formats the biggest difference I was able to hear came from comparing the standard DD and DTS lossy formats to DTS-MA and DD TRU-HD lossless formats. The lossless tracks have much better dynamics and channel seperation of information along with better low level detail you can hear in the background. Yes most Blu Ray discs are outputting 48khz.There are a few concert Blu Ray's that have 24/96khz. The "Akira" disc is 24/192khz! That's the one Blu Ray disc that has produced the biggest difference and the most impressive sound I've heard to date from any disc.
