AR's new DAC digital media bridge

Heard it recently, thinking of buying one. My dilema is in 2 arenas. I have an excellent preamp ( CJ ) and listen to a great deal of vinyl ( SME 20 ) . The DMB has its' own preamp and can run through ethernet or flash drive and be controlled through nifty app's on your ipad. I want to develop a digital library, would like to actually figure out the best means to store the files ( flash? other? ) and have this utility incorporated into my system.

Has anyone done this alternatively? The AR preamp is certainly a decent item but I really d/n need it. The switching is clumsy since I would have to go from the DMB direct to the speakers. ( how do I play the turntable? ) Do I go a different direction ? I really loved the ease and utility of the DMB unit plus, the claim is that through ethernet or flash the source is read from the 'root' menu and it certainly did sound better than USB .
