So I borrowed my parents blue-ray player and bought a copy of POC 3. Man o man!!!

The imaging with the QS8's was stellar! I think i'm going to go for the Panny DMP-BD10ak (DD True HD and DTS HD onboard decoders).

Then you probably shouldn't read this:

The creaking of the wooden ships was very realistic. This wasn't even DD True HD, just uncompressed 5.1 PCM. The sound stage was amazing. All levels were pretty much spot on and everything was very smooth, no abrasive highs or muddy lows.

Oh...and the picture was AMAZING!! Some film grain was left in, making it very film like. There was one point in the beginning, (where some of the pirates were under the floor boards waiting for their cue to shove swords up through the floor) where the detail of the floor boards was stunning!

If you're like me where you have a receiver that does not decode DD True HD and the such, do not worry. Just get a player that decodes the audio internally and passes it as PCM over HDMI. I was sick with the thought that I bought this receiver earlier this year and it was already obsolete...but relieved when I discovered I could use PCM over HDMI.

I already have the HD video setup (HD DVD), but am not setup for HD audio...Not yet anyway...

So are you saying that 5.1 PCM is the same quality as DD True HD? The only difference is that you can only get 5.1 instead of 7.1?

Wouldn't uncompressed and losslessly compressed have to be pretty much identical? I mean, there are still ways to compromise that in certain hardware configurations, but shouldn't they tend to be exactly the same, quality-wise?

I am not even going to pretend to be able to answer that. I'm just saying that the Uncompressed 5.1 PCM sounds amazing and can't wait to hear DD True HD. But as the other posted stated, I believe they are the same, it's just that DD True HD supports up to 7.1 discrete.

I actually prefer Uncompressed 5.1 PCM to DD True HD, it seems more crisp Imo, that may be because it seems to play at a higher volume level than DD True HD when I switch back and forth during a movie, possibly at the same levels they would sound close to the same.


A computer once beat me at chess, but it was no match for me at kick boxing.

Michael,

DD-T-HD has dynamic compression encoded. Unless you can defeat that with your X2, the unpacked version your Denon is receiving may have DC enabled. I’m pretty sure that’s why it is lower than PCM. If it is sent as bitsream, the option is there to disable it, or select the amount of compression. But even with it disabled, there is a 4 db offset that I have not been able to figure out why is there. I had to set up the 3808 to bump up the input level for DD-T-HD. Other than that though, I can’t tell much of a difference in sound quality between it and MPCM. DTS-HD:M on the other hand….holy crap… it’s much mo’ better IMHO.
