Wilson Sophia 1,2, or 3?


I have long been a fan of the Wilson's and recently heard a new pair of Sophia 3 at a dealer. I loved the sound, but the price of a new pair is beyond my budget. As I have bought most of my audio equipment on Audiogon, I have always had good results. Can anyone please tell me the differences between the 1,2, and 3? We would assume that the newer one is better and perhaps more refined, but would a Series 1 at 1/3 the price of a new one be close and good place to start for someone who has never owned a pair of Wilson?
Associated equipment is all ARC, VT100MKII amp, LS26 pre, CD3MKII
Shunyata and Transparent Cables
Thank you

I owned the original Sophias for a brief time. They were pretty good, but nothing special to these ears. Piega P10s and GMA C HDs beat them handily.

As a former Sophia 1 owner, I would say 3- because the 3 is basically a mini-Sasha. It has the same tweet and midrange, just gives up a bit of low end and the two box structure (which can be minimized by speaker location). For 11k this is a good deal imo and 40% less than a used pair of Sashas. They also are much easier to drive which is a boon to amplification choices.
Hi, i just spoke to someone who's very familiar with drivers.
He told me he's 99.9% sure the Wilson Sophia 3's are using an SB Acoustics midbase with the paper cone
He's telling me the Wilson Sasha's are also using the SB Acoustics midbase along with the Aerial 7Ts.
