I have been using the Aurender N100H for two weeks now. At last I've got it set up with 1.1 TB of music onboard. I've installed a mix of files, mostly ALAC, AAC and FLAC files of various Hugh resolutions. Previously, I owned a Simaudio MOON MiND 180 - a device that I sold on three weeks ago. I can tell you that, except for the efficient manner in which they both pass signals on to my DAC, there is little comparison between the two devices.
One expects that in terms of audio quality, devices at these price points will perform with aplomb and they do. Where one separates the wheat from the chaff is in relation to the ease of use of the APP. In this regard, the Aurender app is so far superior to the MOON app that to compare them is to compare chalk and cheese. I won't catalogue the range of difficulties that I had with the MOON app, a utility that seems to be an afterthought in the minds of folk at Simaudio. Crashes were regular events, clicking the back button always took me where I did not want to be, the list is long. On the other hand, in two weeks, I have experienced one crash with the Aurender app and any difficulties that I had with setup really came down to being because of my haste rather than there being a problem with the Aurender or the app.
As as a note of criticism, I do wish that the Aurender Media Manager - a useful database building program, was integrated with Gracenote so that missing album art could be filled in. I've noticed that the app seems to be updated almost every two months - here hoping that my request gets through to the developers. Another criticism that I have of the device is just how complicated it can be just to turn the damned machine on and off. One slip and the Aurender ends up rebuilding its database - a not too lengthy but worrying process.
All in all, I love the machine and would not go back to Simaudio if you gave it to me free of charge.
