I've been using Audirvana for years now (since 2009 when it was a free application) and recently upgraded to Audirvana Plus 2.0 paying upgrade fee for USD 39.00.
You can check it at
http://audirvana.com/ for full details.
I think it's worth to do that since this version is equipped with full visual interface to control and maintain all music files (include iTunes music if you want), especially for flac files.
Following is the screen shots of Preference and some setting arguments are extended with this upgrade.
 |
| You can choose converter as Apple core audio as well. |
 |
| Interesting point is that disable functions are added to prevent stable playback if desired, NICE! |
 |
| You can add folders to and delete to sync music file with visual interface, SO NICE! |
 |
You can choose the order appearance as well.
|
 |
| This maybe the most convenient upgrade feature to maintain metadata visually! |
 |
| iTunes Integrated Mode is still valid and you can see the old interface when you take it. |
