I have one. I use the DA. It is a device whose time has come and gone. Some will say it's time never came as it doesn't sound good. I bought it years ago based on previous Apogee reputation. I'm sure many things sound better now.
As a box it does what it's supposed to. I used it initially for recording 96k/24bit on a TASCAM DA-88, so it had the function I needed. I even had mine upgraded to the Special Edition in the hope of getting something special, but all it's ever been is "good".
