Sonore microRendu audiophile microcomputer with iFi power supply

I am upgrading to the ultraRendu.  But if you're ready to take your USB audio listening experience to the next level at a friendlier price, I highly recommend the microRendu special purpose audio computer. It's been in service for about four months, includes the 2.5 firmware upgrade, and is in like-new condition (with all the original packing, etc.). Also included with the device is a linear iFi power supply that Small Green Computer offers for $50 with the mR. All in, the new value is $690. 
Please note, this is version 1.3 of the device.  But upgrading to version 1.4 through Sonore is an option for a nominal price.
