I picked up a Monoprice tube amp and a pair of Axiom M3V(2 or 3) as a housewarming gift for a friend. I set it up in my conference room to check it out with a Nakamichi CDP. Sound quality was silly good. Excellent. I don't know about the Paradigms, but the Axiom M3s are a perfect pairing with a tube amp.
Don't torment yourself about whether or not you should pull the trigger. Get the M3s and the Monoprice tube amp. You'll love them.
