I just picked up a modded oppo for use as a transport. Coax out to dac, analog out to dvd so wife can play dvds without the stereo. I did not even reliaze it but the oppo has dvd-a capability.What happens when you play a dvd A via coax out to a dac? Will you have any benefit at all or are you limited by the dac. Of course if the disc was remastered well you might hear some benefits.
Follow Ups:
I have a Marantz dv-8500 universal feeding a Chord DAC64 which is 24/96 capable. I have over 30 dvd-a's and I get a 24/96 read on every single one that are 24/96 capable without exception. What you always lose is multi channel playback on digital out.
Fascinating... Unless all of your DVD-As are from the companies that don't copy-protect, this is contrary to everything I've seen on the topic.My DAC doesn't have a display to indicate word length/sample frequency so I have no way of confirming what's being sent from the player. So my reply in this thread was based on what I've read and not personal experience. Maybe other folks who have DACs with displays could chime in on this issue?
A thought... is is possible that you're relying on your PLAYER's display instead of the DAC's?? My player identifies hi-res tracks appropriately on copy-protected discs but I assume I'm still getting a downconverted datastream from the digital out. Oh well... moot point if it's your DAC that confirming 24/96.
Due to copy infringement concerns, the use of an external DAC is of limited utility with DVD-A. Most players downsample hi-res to 16-bit/48kHz at the digital output. And even if a player is capable of outputing a 24-bit PCM datastream, the vast majority of DVD-A discs are copy protected to insure that the 16/48 limit isn't exceeded.The only record companies whose DVD-A discs are not copy-protected are AIX, Classic Records, Chesky, and Telarc (both discs!). Individual releases from other companies have been noted to be missing the copy protection code but they're not common and I've never been able to find a comprehensive listing of them on the internet.
So, to take advantage of a 24-bit DAC you'll need to a) verify that your player isn't limited to 16/48 in hardware or firmware, and b) play only discs from the outfits I mentioned.
Sorry to be the bearer of bad tidings...
