Yeah, lots of Axiomites have the Denon 280X (X=7, 9, etc). In fact, when I did a poll a couple of years ago, asking forum viewers which receiver or pre-amp/amp combo they used for their Axioms, of the over 200 responders, Denon was the brand that was mentioned the most. The overwhelming majority used just a receiver. Amps are not required, generally speaking.
