@robertkpax Robert, The A200 and N200 are both fine machines and the cost savings on the A200 are not insignificant, especially when you figure in an additional power cord and USB and or SPDIF cables too.
Aurender is one of the very few companies (can't think of another now) that has manufactured their own propitiatory software or app. Even Taiko hasn't done this, they use a stripped down version of Windows. Also being Linux based means it's based on Unix server software and doesn't need supplementary USB drivers etc.
I can't say that Aurender is the very best in the World when you compare to some exotic brands but at their price they offer maximum SQ and reliability.
I have owned my N20 for almost two years now, it's constantly switched on and surprises me everyday with what it can do, reliably and without fuss.
