Great AD/DA. Out of production, but may be bought relatively cheap on ebay. I use this in combination with the X-firewire card, and connect the rosetta directly to my macbook pro, using it as a interface.
"Apogee-Kinded" great sound. If you want that "21st Century super pure wide range sounds", will prefer things instead like LYNX STUDIO TECHNOLOGY AURORA 8 or something, but this thing has the punch and power. It just really ROCKS.
