Ok, question. If a DVD or BD has 24bit audio, will the full 24bit signal be fed out of the coaxial digital output of the player, or is it down-converted to 16bits?

I run 2-channel stereo only. I currently have my Panasonic BD30 configured for "PCM" and "no down conversion" am I set up optimally for 2-channel? The panasonic audio is fed via coaxial digital to my Benchmark DAC/PRE which is 24bit capable.

    Just guessing here, but I suspect it will only work over HDMI, because of the copy protection.

    I don't fully understand the question, but my guess is that unless that BD was native 2 channel 24bit audio, the answer would be no.
    Beside the copyright thing, coax has bandwidth issues and I know for a fact is incapable of transmitting hi def and or lossless multi-ch.

    But does coax digital pass a 24bit signal when a DVD is done in 24bit audio?

    I guess what I'm asking is, is the digital output on a DVD/BD player limited to 16bits?

    For instance, I have a James Taylor DVD (Live at the Beacon Theater) that is 24bit/96kHz. If I'm using digital coax out on my player, will my DAC see 24/96kHz at it's input?

    I can't honestly answer that with authority but my guess is yes. Of course, you must have a DAC that is capable of 24/96. Some are not.

    My earlier comment was concerning BD and hi res audio.

    No,with the one exception being that of the defunct DVD-A format should your player be compatible.In which case it will be limited to 16 bits via the SPDIF (coax/optical)due to DRM/copyright issues.
    For instance, I have a James Taylor DVD (Live at the Beacon Theater) that is 24bit/96kHz.
    on DVD or BD?I have the DVD and the 2 ch output is DD not linear PCM.Your DAC1 will not acept the DD bitstream.
    If I'm using digital coax out on my player, will my DAC see 24/96kHz at it's input?
    As long as it is linear PCM.
