Thanks for everybody's advice on the other post. I know that PT 5.1 is Crossplatform easy, so would it be better to keep my NT based PC (382 Mgz SDRAM!!!) and get a Mix or Mix Plus system? I REALLY need the ability to do 24-32 D/A out @ 24bits. Isn't there a cheaper way to do it than the Digi ADAT bridges? What is more expensive upgrading a Mix system to mixplus or just buying a mixplus system? What would my street price expectations be for a new and used NT system?
