I can't find anywhere that it supports APT-X.
But here are a couple suggestions if that is what you want.
Good call. I scoured the package and website when I got it and never found confirmation one way or another. My assumption is that since 'HD Music' seems to be the marketing term for the apt-x profile, it would stand to reason that this sucker has it. But I have absolutely no actual evidence that this is the case.
