Mind if I ask which Cary pieces were used and what brand cabling?
If your room and that one are similar, and/or the gear was your own, you have your answer now on the Wind's abilities.
I've heard systems with great front ends and mid priced ($4K) speakers which just floored me. I've heard reportedly great speakers with decent front ends that just left me feeling... well, OK. That's nice but nothing special.
More than a few times this instance of better stuff up front provides best sound, given the speakers aren't bad to begin with.... and many are not bad to begin with at all.
I consider the whole of the rig's contents... and not JUST the speakers when eyeing a possible speaker upgrade. By that I mean, if they sound pretty good with modest gear in front of them, I feel there is a good chance they'll do better with better... see?
I've seldom been floored outright, when listening to a setup.... anywhere, but especially at a dealership. In a home where it should be setup pretty well, I'd expect a bit better result, but you gotta add in the preffs of the owner too. Therefore I tend to want to drag along a piece of my own that I know pretty well to see how things change after it is inserted.
My understanding of the Winds is that they'll do better with power, as do many speakers. At 86db & 6 ohms in a medium sized room you ought to be able to get away with modest power SS or tube, but I'd not expect anything nearing concert level listening.
Perhaps you can arrange another trip and take your amp and pre to see how they'll respond... oh and your own music. You might just come across some that will astound you but then you have to consider what was up front too. Is or will your front end be superior to that one? It'll need to be to capture that same sound. Been there... Done that... and it's way tuff to emulate or replicate a specific front end setup with dissimilar gear and the same speakers.
The one thing you will know at that point is the ??? speakers are capable of producing super sound IF all else is on track too.
It is always what's up front and the room itself, which accounts for how well speakers will respond.... not the other way around.
Good luck.
