Pro connections: SDIF 2 output

Status
Not open for further replies.
I have a dCS 955 DAC that can take PCM upto 192/24 (using my Purcell upsampler) but also DSD in the professional SDIF-2 format: seperate left, right and clock signals.

So far, I can not use this, as I have no means of outputting DSD in this format. Would it be possible to modify an SACD player to output SDIF-2? I know it is officially not possible to prevent copying, but since you can get the raw datastream out of a lot of players (e.g. Allen Wright) one would only need a circuit to make SDIF-2 out of that...

Anyone have any info or suggestions?

You need the 972/974 to do this. In fact, the 972 sounds better than the Purcell and is much better to use. Meitner used to modifiy the 777ES for SDIF2 but they don't do it any more. This way you can upsample CD to DSD but youi cna't play SACD on DSD. For this you need loads of cash for the Verdi!

How does the 955 sound compared to the 954 which I have?
 
Well, the thing is that I was able to get the units I have now cheap because I worked at dCS for my studies in mechanical engineering :angel:

That is why I have the first ever 955, built from prototype stuff. Because I did not have AES and wanted upsampling, I purchased a 2nd hand Purcell. I would like a 972 but these are far less common ergo more expensive. I am happy with 192/24, but am wondering about DSD/SACD.

I have never heard a direct comparison between 954 and 955, but I expect them to be very simular. The main difference is in the big graphic display which includes metering.

If I ever want SACD I would need a DAC that has firewire (the proffesional models don't have it) and a unit that outputs it, so probably no way to do it other than if I could modify an SACD player to output SACD via SDIF-2.
 
Unfortunately dCS Verdi is not able to output DSD on SDIF-2.

EMM Lab DAC8 is able to convert DSD-optical into DSD-SDIF-2. So you could use Meitner's SACD Drive but it's quite an expensive solution.

I also own a dCS 955 an try to find a drive outputting DSD on SDIF-2...
Last week I try a dCS 974 for DSD upsampling I found it really better than upsampling in PCM 24/192.
