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

Keithr,

The Sophia 3 and Sasha's share the same tweeter, but the midrange is a simplified version, not the same. As I posted before, the sensitivity of the Sasha's allows you to play at lower levels and still fill the room. After owning both, I submit the bass is far from the only difference between the two...but only the individual can determine if the difference is worth 10K.
I think the Sophia 2 matches up best with your equipment and is good enough to handle some upgrading if you desire. I owned the Sophia 1 before my current Watt puppy 8.
