I very sorry Bryston do not support SACD format.
Even a hard driver reading is best than a optical reading I will no support it, because I have many CD and SACD in my library and I do not want lost all the music files in a hard disk crash/failure or any Internet virus etc...
I like to get a disk on the hands or at least a memory stick(permanent memory, not flash memory pen drive like)
