Hi Amala,
I got one and I'm very pleased with it. Never heard such great sounding unit before, the limiters are also great. It's easy to work with. The two 1/4" on the front are handy to have if you fast and easy want to record for example bass, just straight in. I'm a bassplayer myself and for the first time I really can hear what my Precision and Rickenbacker sounds like, it has always been a hell to get a nice bass sound, not now.
Remember it's only A/D conversion, so you need other stuff to do the D/A.
Guess you have the answer already, I'm not so familiar with Digidesign products myself. I use the Digimax with a RME Hammerfall and a Creamware A16 Ultra having the A16 for D/A conversion (monitoring) and extra in and outs, lightpiping it all together.
