I'm running the same set-up (sans the VP150, as I went with the VP100) with the RX-V750, which is about 20 watts/ch. less than the 2400. It kicks some @ss.

In short - you'll have no probs with the 2400. You may even be able to get away with less amplification if you're not trying to overpower the sound. Thats why I still recommend you think about the 1400 or the 750
