The Audio Aero Prestige is a superb sounding player with a preamp and digital inputs. It has a very analog/organic character. In fairness I must say that I am biased because it's the player that I own. But there has been service issues lately since there is no more a distributor in North America, so you have to send to France, but then it will be repaired by the people who built it. The Ayon seems to have the same flexibility (+ USB digital input) but I have not heard it myself but I have friends who owns Ayon CD2 and they are very pleased. They have a distributor in North America now but who knows in the future? For me I recommend the Audio Aero, buy used you'll have superb sound for a reasonnable price but if you want the security of warranty them go for the Ayon. If you can listen to both let your ears decide. Good luck!
