Check out the Totaldac D1. Not cheap but so far nothing has beat it (from what I have read). Check out the mini review on 6 moons. I have no doubt it would sound way, way better than your Ayre (assuming you have a great computer audio set-up including cabling). You can also run it straight into your amps for even more pure sound.
The best of the DACs
I've heard can not perform better than my CD player...most of them not nearly as well. Why would I want to open my wallet and patience to pursue digital downloads and have results not be better than what I already have. I don't mind storing the silver discs....and actually, LP's often sound better than CD's.
