Hi David
I've been waiting for the day when uncompressed PCM is used. Sure, it gobbles up video space, but I think in the future with higher capacity discs and a more efficient video codec this is nothing to worry about. I think people are too fearful of that based on some of the bad titles on DVD with multiple audio soundtracks. I say "guess what??" to those people: "It's not all about video, my friends." I expect the highest quality audio experience possible. Yes, I appreciate great looking video, but my passion for audio is just as much if not just a little more. I love hifi and love my home theater's ability to reproduce high resolution audio (although admittedly I can still do better...and will). I get a great experience out of it.
Some may say that if I was looking for a hifi experience I shouldn't listen to film soundtracks - that is true for many reasons, but that doesn't mean that I should settle for lossy compression formats that sound worse than the quality of a CD. We're in the age of trying to surpass the sound of CD and lossy DD/DTS isn't the direction to take. Unfortunately space limitations on DVD forced the use of DD/DTS - there just isn't enough space on DVD...but now with these new HD disc formats (HD-DVD/Blu-ray) there is enough space (so is said by the makers). "What about space for special features?" some may ask...they can always go on "disc 2" like they do with DVD today. Who says everything MUST be on one disc??
Anyways, PCM, as you can figure out on your own, BLOWS AWAY any of the lossy compression formats which at one time claimed to be "transparent" to the source. That's a load of [ ]...just to make consumers accept it, maybe? DD/DTS are businesses and they have to do what they have to to survive in the marketplace...to get royalties to be put on DVDs and players...I don't think it would be good for their business if we all switched to uncompressed multichannel PCM, would it? Would I care? Nope - they'll have to learn to adapt in other ways because there is still a need for compressed audio in the market - but not for a complete HD-Experience (HD-Ex I should call it and trademark it) - sound & video that surpasses all before it - that's all I care about.
PCM on laserdisc always sounded better - DVD was a step backwards for audio but now Blu-ray is proving we can take steps forward (on these Sony releases). Honestly, I don't trust lossless Dolby TrueHD or DTS-HD master audio...it's still compression and I'm sure they have their own sonic signature to the sound (remember they promised their lossy codecs were transparent!) With audio anything can get in the way...it's a finicky and sensitive hobby (both the technology and the enthusiasts!) And for those computer people out there who may argue me on this...I don't compare this to .zip files etc...I'd be very surprised if either lossless audio compression formats blow me away as uncompressed PCM audio did. So far Dolby Digital Plus has done little to impress me - you still have to "listen hard" to hear it.
Sony has mentioned that uncompressed 24/96 PCM "is coming" on Blu-ray and that is exciting. I imagine once 50Gb discs are available we may start seeing this. I believe THE FILM is the #1 priority and all else is 2nd. I want the highest performance possible especially since I can see/hear it.
Even though the PCM on these discs are 16/48 - it's not inferior to DD/DTS that discard all of those fine details we are supposed to appreciate from the 24/48(24/96) audio masters they encode. With uncompressed PCM, we are supposed to be hearing all of 16/48 - no loss in detail, no compression. Listening to it makes you realize what we've been missing all this time. What really blows me away is that I'm hearing it through fairly cheap DACs in the Samsung player. Once connected with HDMI to a preamp/receiver with reputable DACs I believe the differences will be even greater.
