Received mRendu yesterday and, despite my computer illiteracy, have it up and running using JRiver - got the Gizmo remote app to work as well. But whenever I play a file with a sample rate greater than 44 ( 88, 96, 192 ) my DAC shows it playing back at 48. I checked the DAC status page on Sonicorcbiter.com and it correctly identifies it and shows it is Hi Rez capable. JRiver is set to not change the Sample Rate and this works correctly when I go from PC to DAC. Apparently there is something else I need to do. BTW, clarity is noticeably improved compared to PC direct to DAC. While not earthshaking, on 1 of my test tracks where artists are talking softly in the background it is now clearer than ever.
