Mini is no more Al, but they let anybody with a Mini license upgrade to Amarra. They now have Amarra HiFi ($49), Amarra ($189) and Amarra Symphony ($495) (current Amarra users get a free upgrade with their license). The main difference between HiFi and full Amarra is that the Hifi is pretty much tied to iTunes and it is lower ( but still 192 kHz) resolution. They have a nice comparison on their website. I just started using airplay but so far it is pretty good. I previously used remote HD which worked just fine. I basically just want to be able to lean back in the chair like a slug and it works fine for that.
