Why is SACD so restricted?


Recommended Posts

SACD was originally designed as a way to backup masters by Sony/Philips. This was told to me in a discussion with people from DCS who helped design it.

I assume very few SACD players is produced today. There can’t be much royalties to collect these days.

If the same DRM etc is used in PlayStation, maybe it’s an issue ?


I was thinking maybe someone was able to get in touch with the right people as Sony, to see if the format could be “set free”. Is their plan to keep it forever? Is it for sale ?

 

I know of one product that is legally able to extract SACD out to SPDIF. Cost $1000. 

 

 

It is not that, it is the chips (in the laser drives) to help decode the data stream are no longer made by Sony. As such, there is a limited amount of drives that can be made. Also there are few manufacturers of those drives, Esoteric is one.

 

SPDIF only allows 96/24 max for output so not sure about how good the copy would be.

You still need both sides to be compliant with that 192/24 of the SPDIF or it will be just 96/24 - just saying.

 

The chip is used for the protection of the SACD format.

Aha. Well hopefully they can just reprogram it 😀

 

And I think AES/EBU is up to 8 channels also. 

 

Well according to DCS, that is why they stopped making SACD players (if I remember the discussion we had at an audio event they were at).

So, i.Link components have to have DTCP (Digital Transmission Copy Protection) otherwise both DVD and SACD cannot be played. hmmm..... 🙀

Sony stopped producing the chips 3-5 years ago, I was told. Sony has enough chips for themselves but will not sell them to other drive producers
