I have owned a Capitole Mk 2 since they were introduced about a year ago. Just because they have the P4 chip doesn't mean all is well. I had a list of about 15 different problems with the Capitole and finally had to send it in and have a complete circuit board replacment. It seems to be working fine other than the fact that the counter still won't acurately read the remain time on a track, it doensn't seem like to much to expect a 9k CD player to perform flawless, which Audio Aero players don't. I also have the Audio Aero Prima CD player in another system and after a month it is now having problems with the display fading in and out. Certainly don't buy Audio Aero gear based on reliablility or build quality, they are very weak there. As far as sound goes they are fantastic, the Prima is a steal, it's close to as good as the Capitole Mk 2. Customer support is good, they are very interested in making sure their players are working as they should. Basically if sound quality is not your number one priority I would look for something besides Audio Aero, cause really thats all they have going for them.
