CS8406, CS8416 => 192kHz SPDIF

Dave · 8th January 2003, 03:25 AM

It appears the SPDIF standard has now been raised to support 192KHz. Crystal have released the CS8416 and CS8406.

Does anyone know if this interface will be the standard for DVD-Audio?

Oh, I have to look into this...

Current DVD-Audio players only output downsampled 16/48 on their S/PDIF out when playing DVD-audio... Yes - not even 24/96.

At least it's like that in Europe.

Our best friend, the music industry, urged the manufacturers not to allow high resolution digital copies. That's why commercial separate drive/DAC units all have proprietary interfaces.

Technically, I doubt whether a 192 kHz S/PDIF is really what we want. An all new digital audio interface designed not to repeat all mistakes and false assumptions back from the eighties would be my preferred solution.

When cheap 192 kHz interface chips are available, there is at least a chance some manufacturers will gice us access to high resolution digital audio to feed our DACs.

Hey folk, don't be so pesimistic, I heard Pioneer DVD player have a digital out in this rig, it had truly 24/192, but I never heard this rig use with DAC capability feed w/ 192, btw I got this info for Stereophile Mag February 2001

I new Pioneer supported 24/96 digital out while nearly all others downsampled. I didn't know that some had 24/192. What model was it?

Remember, it's a difference whether your are playing an audio track on a DVD-Video (most players can output 24/96 S/PDIF) or a "real" DVD-Audio (most, maybe all players downsample to 16/48).

I've seen some players using a firewire interface for high resolution digital audio. Never seen any specs or even receiver chips for this, though.

Let's make a list: Players suitable for DVD-Audio playback w/ external 24/96 or even 24/192 DIY DACs. Does anyone know models that do output more than 16/48 digitally from a DVD-audio?
