i am the lucky owner of a cairn 4808a amplifier and a audio aero prima cd player. i own the two for one year now. i must say if you enjoy classical music and jazz you have to choose (when your budget allows it)) for the audio aero. more definition, room, soudstage etc. than the cairn fog, but a little bit more coloured than the fog as well (and you have to like that). i obviously compared the two when i was buying the amplifier but it was a easy pick.
good luck with your decision.
