I recommend you post your question on the Wilson Audio forum, or at least search the archives. There have been many posts about your topic and many have written about their experiences of going from Sophia 2 to Sasha. You will also find lots of information about partnering equipment and set up.

Of course only you can decide and I encourage you to listen for yourself.
