Really interesting product, though I've never heard of them and wonder who they are. The I2S and word clock functions, as well as SB3 power are really nice. Unfortunately, the Duet's going to need 9V instead of 5V. I like having some digital input switching - USB, I2S, SPDIF, Optical, etc. to hook up all the alternatives to the CDP I have now - SB2, Airport Express from PC's, and PC's direct via USB.
Quite unique. Hopefully a sign of more products like this hitting the market to address the variety of digital sources.
