How to get iTunes to play FLAC

Scanned the web and Agon and cannot find any definitive method of achieving this with HD FLAC files

Found one suggestion but it only handled 16/44 - I would like 24/192

I am streaming from an iMac, using iTunes as the interface because my droid app "Retune" controls it from my tablet

I have installed Audirvanna and I like it's integration with the iTunes/Retune setup

Has anyone found a method of playing 24/192 FLAC from within iTunes that would not conflict with my current setup - without having to convert the files to some other format like AIFF?

Many Thanks
