Vandersteen 7s

First review I have read is from Fremer, and its glowing. Wish I had the space and cash to even consider a purchase. Have others heard these?
I heard them at Definitive a couple weeks ago. insanely good. insanely expensive. probably not having the $ is a good thing - if you hear them you'll want them.
Fremer,fremer,fremer.Does his endorsement make everything a "must have"? I would think Mr.Vandersteen's speakers could speak for themselves.
I understand original 5A owners will be able to upgrade (almost) their 7' drivers and electronics, but same cabinet. I was told the result is about 80% of the 7's.
