The vandys can boogie, no worries there. Look at the long thread going which I added to yesterday after just hearing Vandersteen 2ce sigs for the first time in years. I still can't get over the sound quality for the money. There are many many speakers out there that are waaaaay over priced compared to these. And they should go great with your adcoms. I think they need some power and control.
Good luck!
