Great sound, killer UI, gapless playback

This is one of those rare apps that is delightful right out of the gate. Its claim to fame is a unique crossfeed feature that gives a subtle, speaker-like sound. I appreciate how this feature can be combined with the EQ to make the music feel alive instead of squashed. The effect is tasteful instead of gimmicky like some EQs.

Another awesome feature is the ability to save output presets that are customized for the sets of headphones I use (Shure, Etymotic, Apple). Its great how (by default) the app prompts you to choose the right output preset whenever you plug in your headphones. Another excellent feature for headphone listeners is the Dosimeter, which gives you a current & average loudness measurement so that you can protect your hearing.

What I didnt know when I bought it is that the UI is fantastic and could easily be a showcase app for iOS. The navigation of your music library is easy and classy. Keep in mind that the only albums and artists under your library are those youve stored on the device, not those you might stream from iTunes Match. A+ app! I even bought all the in-app upgrades.
