I can’t recall if I’ve ever heard the Dueventi, but I’ve heard the MasterSound BoX and the 845 and they are both stellar. Excellent pairing with the Rosso.Things work out best for those who make the best of the way things work out.-John Wooden

I really liked MastersounD. I can't believe it, I also had the BoX but for the life of me, can't remember what I did with them.
Solid amp here. -
Again, Beautiful!!
