No, there isn't. That hardware would be against the copyright/protection mechanisms that Sony put in place in the SACD scarletbook spec.
My advise is to buy the standard Mytek stereo DSD 192k DAC that Michal has announced/delivered, and do DSD-native over USB. This would be possible with the PS3 hack (software breaking the code) mentioned in my SACD-PS3 thread
http://www.audiocircle.com/index.php?topic=95396.0Then taking those DSDIFF files and sending them via USB to the regular DAC (via Pure Music's DSD capability). It isn't a multichannel solution (PS3 rips are, Pure Music isn't) though.......yet! I spoke with Rob at PM yesterday and told him to get there (mutlicahnnel) soon cuz I'd like a DSD multichannel player to go with something like an 8x192DSD.
