Okay, I'm finalizing the last few purchases and I'm down to buying
the right DVD player. I have a TAE9000ES pre/pro which accepts
24/96 on the DVD digital input but not the CD (per the manual).
So I plan to use my current CD player for older CDs and any new
DTS CDs and DVDs will have to play in the DVD unit. With all the
talk about which DVD players that do and don't output 24/96 audio
and/or data from the digital out I'm wondering what to do.
I understand that DVD audio discs that were recorded at 24/96
would be degraded (although perhaps not noticeably) if the
player downconverted to 48KHz sampling. Is the audio from
DTS/AC-3 DVD's SUPPOSED TO BE reproduced (was it recorded
that way) in 24/96?
What's the difference between audio and data coming out the
digital port? Is it the difference between a PCM bitstream
and encoded mutlichannel sound?
Thanks for you help.
John,
I am not an expert in this area, but here are some of my thoughts (which I admit may be wrong since I am still learning myself):
I think, but am not positive, that DVD's currently don't have enough bandwidth to support 5.1 channels of 24/96, so instead they use 16/48 for all the channels. As far as 24/96, the Chesky record label (they have a website) makes a couple of dozen DVD audio discs encoded in 2-channel 24/96 for stereo listening. But I believe that only Pioneer and Theta DVD players send out a 24/96 bitstream. Every other player on the market downsamples the signal to 16/48. MSB (website = msbtech.com), however, will modify any DVD player to output a pure 24/96 signal for $385. I am considering doing this to my Panasonic A310, since I just bought a Wadia 830 with a 24/96 DAC.
All of this has nothing to do with the new DVD-Audio specification. That spec is still being worked on. Hope this helps, I am still trying to hash it out myself.
The Pioneer players output 24/96. In fact the reason the higher end units do is that they are based on Pioneer players.You only get this in two channel mode though.
