I did have a Classe 5 with a B&K amp. I got rid of the B&K amp and replaced it with Musical Fidelity A3.2 which I haven't recieved yet. I know this has a pre-amp out. I have a odyssey audio amp that I will get back. I don't think I need the Classe but was wondering what opinions were. If the Classe is a better pre-amp I may end up keeping it.
