One way iBasso could do is provide an interface (that does the hi-res plumbing) that PowerAmp could call. Or, if PowerAmp already has an interface, then, iBasso can implement it. By an interface here, I mean a software interface, not a UI interface. This way, both parties' intellectual property are protected. Whether or not PowerAmp and iBasso are willing to work together and deem that it is worth the effort is another matter.
