I had a pair of Sonatina II's I purchased with bad midrange drivers. I live near silverline and brought them to Alan to replace the mids. While I was there he modified the crossover which gave them a more transparent sound, more like the newer silverlines. This was when the III's were just released. The difference between the II's and III's was very noticeable in the short audition I heard. You may just want to sell yours and pick up a used pair of III's.
Anyway Alan is a tinkerer and is always modding his own stuff. I think I remember reading a post by someone who was disatisfy with the sound of his II and Alan replace the tweeters with higher quality ones. It maybe that no 2 sonatina's are exactly alike. Guess you could contact him and see what he suggests.
