I own Tekton DIs and have been happy with them, had them for about 3-4 years. I haven't experienced a lot of speakers but have owned Alon IIs, Divas, Maggie 3.6 (I think) and some bookshelf SVSs. This is totally subjective of course but the Tektons are my 2nd favorite speaker I've owned and they are my current speakers.
I think they do a lot of things well--probably the thing I like the most about them is they fill the room with sound--I feel immersed in it which none of the other speakers quite did. But interestingly enough I find myself looking to buy some new speakers, try to step up and have been thinking about Klipsch Heresy speakers, but it's just a thought at this point, haven't heard any but am going to see what I can find this weekend.
BTW, I like the look of the DIs, but I've always been a little warped.
