Vandersteen 2c vs Thiel CS2

Well, I can't wait to try this as I've replaced some rebuilt Kef Calindas and some Magnepans with a set of Vandersteen 2CI's and I just ordered some Thiels 2.2 in great shape or so the owner tells me.  I put the Vandersteens on feet which improved the sound pretty dramatically. I listen primarily to Classical, (opera, piano and lately more symphonic music) and more and more Jazz.  About 10% of what I listen to is classic rock.

My brother in law has some Spendors which he brought over and hooked up to my system.  To both of us they sounded much better than both the Magnepans and the KEF Calindas I have( just a better high end0.  That being said, when I go over to his house now after listening to the Vandersteens I bought, his Spendors sound flat and without dimension to me.  I can't wait to listen to the Thiels I ordered though to see what they sound like.  I think though, I am going to stop buying speakers after this.  Perhaps move onto new tube amps/preamps.
