Can you give me more details. What software? Is this a commercial package? What transport do you use that will read and SACD or DVD-A on a PC? Will it also do BDs? Once you have it ripped how do you get it to your pre/pro? Is it an HDMI connection? What about the SQ as compared to playing the media directly from a dedicated source? If this does what I think you are saying then I will want to build one of my own, so please provide enough information.

Thank You,
Mark
