Sounds very good, but lacks library management features

To be honest, Fidelia sounds very, very good upsampling uncompressed (FLAC) files using Goodhertz - its among the best Mac players available. But, apparently nobody has told Audiofile Engineering that skeuomorphism is out, and its library management is all but non-existent. I was also a little dissaponted with the recent update (version 1.6.3), having patiently waitied so long for it. If you have a large library, you might want to look for something else. Otherwise, Fidelia is a great sounding player, even in the basic version.
