Dolby True HD vs. DTS HD

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.

Stratman what is the Akira title and does amazon have it. thanks Jeff

Longhorn if your Marantz receiver doesn't decode the HD formats you won't be able to tell much of a difference. You will need to use the multichannel outputs on your Bluray player into the multichannel inputs on your Marantz to enjoy the true benefits of HD audio.

Longhorn, you're not even listening to lossless. The Marantz can't decode it. Its HDMI capability is limited to HDMI 1.2, so its HDMI feature is only functioning as an HD video switcher; it's not extracting the audio bitstream from your Blu-ray. The TrueHD and DTS-MA lossless bitstreams require HDMI 1.3. You're evidently getting your bitstream over the optical digital link, which doesn't have the bandwidth to transmit lossless multichannel. The PS3 downconverts the lossless bitstream to DVD-standard DD or DTS, which is lossy. By this method the Blu-rays still sound a bit better than standard DVD because the downconvert operates at a higher bit rate than the DVDs did.
