A comparison Vandersteen 5A-Coincident PRE

I have heard the Vandersteens 5A’s in person but not the Coincident Pure Reference Extremes. I have been reading some of the threads here about the qualities of both (mostly the Vandersteens) but would like your input as to how both compare. My (almost) 40 year old speakers are Infinity RS 1B’s and I am quite happy with them. I power them with 2 McIntosh 275’s bi amped and a Perreaux 3150 on the woofers. My music taste is mostly classical/jazz/some rock. My room is approx. 17x 28x 8. I am curious as to how each would compare to my current Infinities. Thank you!
