Yes, it is possible to convert 24/96 FLAC files to AIFF using Amarra HiFi.
However, according to Amarra, when this is done they get down-converted to
16/44.1. This rather defeats my new found interested in HD audio.
Thanks for the tip on Foobar2000 (no good for me as I use a Mac) and
Audivarna, I will investigate.
