The Classe' integrated is a fine piece of gear.... however if you want tube majic... sell the Classe' and get a true tube integrated like Manley... uses EL84 output tube and can be oerated in triode mode as well a ultralinier. Lots of tube majic there at a very reasonable price. There other good choices too. I would spend some time learning about tubes and the way they sound before making a choice.
Good Luck
