Dolby True HD vs. DTS HD

Very slight, if any difference. I have heard that DTS uses less compression than Dolby, so that is the reason for marginally better sound.

However, I still cannot hear the difference between regular bitstream and the new lossless codecs.

Hmmm...I always thought it was slight, I am going to do some A-B testing tonight to be sure all my settings are correct.

I'm currently decoding it through my PS3 and sending it (via HDMI) a PCM DTS HD MA or DD TD signal to a Marantz SR8001 using as a processor.

Times like this I wish I knew an audiophile personally that can help me test my system!

I disagree with you Johnny. While true that the Marantz cannot convert the native bitstream DTS HD/DD THD it can read a PCM signal.

My PS3 is decoding the DTS HD/DD THD into a PCM signal and sending it to my Marantz via HDMI (no optical cable used).

I have confirmed this by checking the output on my PS3 (hitting select during playback) and it shows what is being converted within the player.

I was also skeptical about this at first and I have double-checked numerous AVS forum topics regarding this same exact set-up.

BTW, I have A-B tested War of the Worlds and yes, it is more 'dynamic' on lossless format, not necessarily louder though.
