I made it a point to audition both as they were two highly rated speakers that performed above their price points.
I made it a point to listen to the music as well as movie dialogue and I picked a movie that had dialogue that gave my present speakers (and pretty much every other speaker I auditioned) problems in resolving the finer details.
And just to be up front, I love ribbons and planer speakers. That is pretty much what I have bought.
The short version was that I thought they were very close. I went back and forth with the midrange and treble especially with the music and the hard to resolve dialogue. I was surprised that the Tekton not only held it's own against the ribbon but I actually thought it might have even more resolution - but it was close wither way. The tweeter/midrange array does it's job.
I did not hear any of the warmness that was mentioned. I thought it was very neutral, but that is going to be something that only your ears can tell you.
Also, the version I heard was the standard $3000 buy direct from Tekton version. I know the dealer version has some different internals and it is more expensive, but I'm not sure it's worth it --- but I have not heard them back to back. The standard $3000 version was what I heard and it was the equal to the Focus and no comparison to the Signatures which are actually closer to the Tekton price point.
As far as finish and looks, there is no comparison. The Legacy speakers are much nicer to look at. Real wood veneers, etc. Very well done. The Tektons I heard had the standard soft glow finish paint. I personally don't like that finish, but they offer an upgraded automobile finish gloss that is about what the Wilson speakers have on them. They are an upgrade (I think $500 but not sure). I would go with that and you have a nice looking (but not wood veneer speaker for a whole lot less money.
You should listen to both if you can before you decide.
