Never heard the Vandy's but spent many hours with an amazing sound from Cornwalls, as owned by a friend, driving them with - of all things - a receiver. One or two clicks down on mids, one up on highs and magic!!! I heard these same speakers (after he sold them) in another house - NOT GOOD. I was so impressed with my friend's original sound I demoed a pair at home (on Crown amps - mistake!). Very midrangey and a quick return to the store. Moral of the story: In the right circumstances, Corwalls are VERY impressive. The dynamics are so much closer to live music! But, in the wrong system or room, not so good. I would suggest a tube amp.
