Hi Antun,
This is not possible, we are using a sata optics drive, unless we can buy a sata drive that plays sacd's it won't be possible. The original Sony PS3 could play audio cd's, dvd's, blurays and sacd's and in likley good was also a sata drive, but not one we could use as we could never have bought it. The only SACD drives we can buy are proprietary and have the Dac's built in to prevent copying. Seriously this is never going to happen.... Please for all that is holy stop asking!
Cheers
Chris
