Your priorities will determine how much you like Fidelia

On the (significant) plus side, the sound quality is great. If you’ve been playing lossless or HD files through iTunes, Fidelia will shock you with how much better they can sound. Simply put, it’s not possible to hear the full potential of your high-quality music through iTunes.

On the downside, library management with Fidelio, even simply accessing the songs you’re looking for without a text seach, is just flat-out terrible. If you’re used to calling up a desired song quickly in iTunes, Fidelia will be an extreme disappointment. Don’t even think about browsing your music with Fidelia; it’s impossible. Essentially, the only way to use the app is to start with a specific song or album in mind, and then use text search to find it, open it, and enjoy the sound quality that Fidelia offers. Really, Fidelia’s file management is no better than just using the finder in OS X, which can be frustrating.

Also, the app can be VERY slow, especially if your library is a large one (which I’d guess it is for most folks who’d be interested in an app like this.)

Bottom line: if you’re willing to sacrifice all elements of convenience that iTunes has taught you are “normal,” Fidelia will deliver eye-popping sound quality. For me, that’s a fair trade-off, at least in certain situations. But I definitely find myself screaming in frustration at this app a lot.
