I haven't heard it but have had their C-5xeMP for a short time. It was excellent but as with David I would also say the sound tended a little to the warm or polite side (maybe part of the Ayre house sound if there is one?), which may be good or bad depending on your system/tastes. I've also had a Bel Canto DAC3VB in my system that unearthed a lot more detail while also sounding very musical and not overly analytical. The Ayre had more of an upfront presentation with lots of flesh on the bone while the Bel Canto was more of a mid-hall perspective allowing me to "see" the whole of the performance venue more clearly. Again, personal preference obviously comes into play.
Apart from my personal experience, of the many reviews I've read the Ayre seems to fall a bit short of the DACs from Bel Canto, Berkeley, and Weiss, but in fairness I think all those are priced significanlty higher than the Ayre and may be out of your price range. On the cheaper end I'd be curious how the Ayre would hold up against something like the Metrum Octave that may have a similar kind of sound. Then again if you're looking for a little warmer yet still nicely detailed presentation the Ayre may be a relative bargain. The good news is DACs are obviously small and light so it should be easy for you to compare a few without too much effort relatively speaking. Hope this helps and best of luck.
