I have a denon worth 600$ that powers the VP150 and QS8 and it has no problems at all. It gives 70wpc into 8 ohms, 110 wpc into 6ohms. They play louder without distortion than my ears can take in a 20 by 12 room (no carpet, 11 foot ceilings).

I think any Onkyo will have very similar power sections to the Denon I have.
