Great sound, killer UI, gapless playback

OuterSpaceBass

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 EQ's.

Another awesome feature is the ability to save output presets that are customized for the sets of headphones I use (Shure, Etymotic, Apple). It's 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 didn't 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 you've stored on the device, not those you might stream from iTunes Match. A+ app! I even bought all the in-app upgrades.

Spent some time with it, really love it

Bottom line: this is a great app that sounds better and more faithful to the original recording than Apple's music app, even without using the additional processing. The additional processing (cross feed, eq) is a bonus and with it applied judiciously you can create a pretty solid audiophile experience on an iOS device.

Got a new pair of Onkyo headphones (which I really like) that sounded too harsh in the upper-midrange in Apple's music app. I tried Can Opener and it immediately (even without any processing applied) provided a less harsh, more contoured, more faithful reproduction. I bought the Hi-Fi Pack to try out their sample rate conversion for my higher sample rate Apple Lossless format files. Sounds good. Not a dramatic difference but smoother, seems to add a bit of detail, though it is not necessary to get a great sound. Other nice touch is a more fine-tuned volume control, and I love the dosimeter. Cross feed is very well done, but I prefer a subtle setting. Fortunately, Can Opener gives you complete control over the amount and angle of the cross feed. Great app. Thanks.

By far the best application I've bought.

Being a music lover and possessing pretty decent headphones (Beyerdynamic DT 880's), I saw all the good reviews of this app and though I'd check it out, though I was a bit skeptical. Now that I've spent some time with it, I'm truly amazed! I run the speaker angle maxed with the amount set to 75%, so it's subtle yet makes a huge difference in the listening experience. It sounds as though the gap between the left and right drivers is filled, providing better spacing and better (not "more") bass. I don't mess with the EQ that much since my headphones are already pretty flat, but it seems very decent. The UI is simple and well-animated. It's nearly perfect. My only request is for an option to have a traditional left-to-right scrubbing bar, as the circular one does get on my nerves at times.

This is a must-have for audiophiles, period. You won't be disappointed in your purchase.

UPDATE: I'd like to see proper scaling for the iPhone 6. It doesn't look bad; the UI just looks a bit too large and a tiny bit pixelated at the moment.
