Vandersteen 2ce vs Vandersteen 2ce Signature II

Has anyone heard both of these speakers and have an opinion of the differences? I have a dealer near me where I can hear the signature II's but not the older model. Are the signature II's substantial better? It looks like on Agon I can get the older model for pretty cheap.

I'm considering switching from Sonus Faber Luito monitors to the Vandersteen because I have an Ayre Ax-7e and I have heard the Vandersteen are a magical match with Ayre products.
