Stoev, thanks for the feedback we'll keep that in mind, we've had a couple requests for a DAC only version so far. If you shoot me an email (in my HN profile) I can reach out to you with updates.

And yes, Amp will ship with a setup app that calibrates to you and your headphones, but after the setup process, you can use any music player you like (the case will do all the processing). And the case will be able to detect different headphones as well, so you can assign specific audio profiles to each set of cans.
