I have the Sig IIs, and I also really like them for the money.
With regard to some of the advantages you noticed of the Thiels over the Legacys, which I do not doubt, I wonder if some of that can be attributed to the quality of the capacitors in the Sigs. I think I remember reading some years ago that some folks felt the weakest part of Legacy speakers were their capacitors. And that some people had upgraded them, with results that mirror some of your comments on what you like about the Thiels.
I am interested in this because I am starting to think about upgrading the caps in my Sig IIs. I know next to nothing about how to do that, but am willing to learn.
