I am pretty sure that Audirvana, Pure Music, and Amarra only work with OSX and iTunes as the library. JRiver was originally developed for PC and is now Mac compatible.
Macdonj - try the JRiver software out for a bit. I think you will like it. At this point I am now getting into running Minimserver on my Mac Mini and bypassing JRiver, except to curate my library. I use PlugPlayer on my iPad and Android to access my music folders off the server. I will be expanding this in the near future but for now the results have been very good. I may go back to JRiver if and when I start using DSD.
