hi.
i have a pair of auditors that i am actually driving with the sonus faber integrated, musica. few people know about this amp, but it was designed by sf as an in-house reference. i am very happy with it, not a lot of power, but very musical. you can see what it looks like on their website, or at sumiko audio's website (with pricing)
Separately, what did you decide? did you listen to the levinson?
