I owned a Classe5 many years ago and thought it was a quite nice peice.Sound was "tube like" .A touch on the dark side (but not much ) Very smooth and listenable. The only problem i can see is the age of the peice.Though made to last a long time ,its been a while since the manufacturing date..If you can find a good,low hours peice and you dont mind a little warmish sound go for it ,but just remember it a bit long in the tooth........
