Building a music server with Ayre DX-5


Need advice building a music server around Ayre DX-5.

Current thoughts. Mac Mini with SSD & 8 MG RAM connected to DX-5 by USB cable. Mac Mini on home network with music on a Drobo FS NAS all connected by Ethernet cable and controlling Mini from listening seat via iPad with WiFi connection.

Anyone done anything similar? Thoughts?

Any links to the "mods" or modders needed to use the USB output of the Touch? A quick google found other people asking about this, but no solutions...
What are everyone's thoughts on the Ayre DX-5 using the USB input? How does it compare to older ayre products or other digital sources you have used? Soundstage, tonality, imaging, organic versus analytic? Thanks.
