I recently purchased a demo 4TB Aurender N100 to replace my mac mini as a music sever in the big rig. I have managed to get my music downloaded and it sounds wonderful. More detailed yet warmer, the antithesis of a "computer sound" as my wife calls it. The problem I have having is that this thing is so much more complicated to use than the mac mini (I have been using Windows (gasp!) and J River). I am trying to figure out how to delete some of the duplicates caused by my downloading music which was already on the hard drive when I got it (I think I have like 5 different versions of Sgt Pepper and I really only want the most recent 24/96 i just got from HD tracks). I read the instructions but its like trying to decipher an alien language for an old man like me! Have any of you mastered the Aurender yet?
