Wilson Audio upgrade path

I've been using Wilson Audio speakers for a long time. I'm listening mostly to classical music. Recently I started reading about the Alexia series and found few of them on the used market.
Is anybody aware of an upgrade path from Alexia series 1 to the Alexia series 2?
Any thoughts on this subject.
@georgehifi  Thanks for the link. Good read.

@shadorne  What's your take on the Alexia 2? Thanks.
We are a Wilson Audio Dealer.

The Alexia Series 2 is an amazing speaker. If you reside in Southern California, I would love to invite you to experience this speaker.
If you live elsewhere, pick a local dealer. They will be very important in support down the line for you.
