Re: newbie question- DVD with Dac?

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...
