Martin Logan reQuests vs newer Martin Logan offerings


I'm looking at buying a friend's Martin Logan reQuests but wondering how they might compare to newer ML products.  Have they really come that far?  

Thoughts?

Cool good info..  But you're saying ML comes with ARC?  My Anthem amp has ARC already.  I'm assuming it's the same.
Yes, it's essentially the same.  With ML speakers, it's used only for optimizing the bass response. 

I suggest posting your question over at http://www.martinloganowners.com/forum/ if you'd like more responses.
I owned ML's for almost 15 years. The stator panel definitely has a shelf life. I'd communicate with ML about the Requests. If the panels need changing out, that's not a inconsiderable cost.
