Amp upgrade for Contour 60's

Hello Two left, thanks for responding. The used Ayre AX 5 Twenty would run about $6,100. I missed out on a used 600i couple months ago. I have heard the Contour 30’s with the 600I and it was a great combination. Don’t have anything against a good integrated but concerned the 600i would be a little light on power output. I love the Sim Audio gear, and would buy the 860 power amp in a heartbeat if I could afford it. It will be hard for me to go over $6500 for a power amp, and considering Ayre AX 5 doubles to 350 per channel at 4 ohms, I don’t know what else is out there in that quality league with that kind of power output for the price. 

I have a hegel H360 and am considering a pair of contour 60's. If anyone's heard the combo I would appreciate impressions.
