I don't think so - I don't know all the details of the duet, but I know the engineering team at Apogee pretty well (from a Vendor point of view).
I'm sure he won't mind me saying this:
Lucas Van Der Mee - the analog and mixed signal designer there is probably one of the most talented designers I've met in Pro Audio. He really is one of the few designers out there that actually pulls a chip apart, finds it's strengths and weaknesses, then gets the best out of the chip with some external circuitry.
Their digital design group is equally as talented. I believe that one of the reasons they went Apple only is that they can guarantee the OS and the Hardware. That makes it infinately easier to support than the "oh, I built my own PC" market :grin:
