No.

Unfortunately I do not have means of offering a demo version as I’m against adding DRM (Digital Rights Management) to Colibri besides the default Gatekeeper service Apple provides for all App Store apps automatically.

Any added layer of cryptographic protection would also mean computing power usage overhead – something that is contrary to the core concept of Colibri’s existence! I’d rather spend time developing Colibri than deal with in-app purchase verification.

However, there is the Colibri DAC/DSD Test application free from the Mac AppStore with which you can test out how your audio setup would sound with Colibri (it uses the same audio core). It is also great if you are wondering whether your DAC would work with Colibri.

For a list of tested devices, please check the DSD page here.
