The folks who say that Thiels sound harsh are sadly mistaken (my opinion). I myself have been pondering whether to keep the Thiel 2.3's which I have enjoyed for the past six years or to upgrade to the Sophias. The Sophias have a better extended lower range are a little better in overall detail, dynamics and soundstage (wider & deeper). However, unless you have good front end components, can sound a tad forward. The Thiels on the other hand give the Wilsons a real good run for their money. The cabinets aren't as quiet as the Wilsons and could be a little better in sound stage depth. However, match it with some good tubes and get them placed properly in your room and boy do they sound fantastic. If you love acoustic music and vocals and want to hear subtle changes/differences in any equipment, the Thiels will clearly reveal them. Contrary to one of the above posts, there is absolutely NO lack in emotional conveyance of the music. Every time I hear Alison Krauss, Joni Michell or Mary Chapin Carpenter though them, I tend to close my eyes and smile. Although I love the Sophias, every time I compare them to the Thiels, I can't seem to justify spending 3 times more for them. However, being the nut I am will eventually get them. With the Thiels you get a lot for your money. Both are fantastic speakers designed by two of the best engineers. For now, my heart says Wilsons, but my wallet says Thiels and I know that I will be extremely happy with either.
