Tekton Double Impacts

Anybody out there heard these??

I have dedicated audio room 14.5x20.5x9 ft.  Currently have Marantz Reference CD/Intergrated paired to Magnepan 1.7's with REL T-7 subs.  For the vast majority of music I love this system.  The only nit pick is that it is lacking/limited in covering say below 35 hz or so.  For the first time actually buzzed the panel with an organ sacd. Bummer.  Thought of upgrading subs to rythmicks but then I will need to high pass the 1.7's.  Really don't want to deal with that approach.

Enter the Double Impacts.  Many interesting things here.  Would certainly have a different set of strengths here.  Dynamics, claimed bottom octave coverage in one package, suspect a good match to current electronics.

I've read all the threads here so we do not need to rehash that.  Just wondering if others out there have FIRST HAND experience with these or other Tekton speakers

Hi Terry,
As you know there are a number of Double Impact owners very happily using solid state amplifiers. Do you plan to use your Pass Labs XA 60 .8 with the Ulfberths to give a contrast comparison to your Triode Labs 2A3 SET. I strongly suspect that the Ulfberths will reveal all that both fine amplifiers have to offer and their differences.
@jollygreenaudiophile2 , Mark at Linear Tube Audio in Takoma Park told me months ago that Eric was sending him a pair of speakers. I waited for quite a while to listen to them but they never showed up. I got impatient and went ahead and ordered them anyway. No regrets. Maybe I'm the only one that has them in the Baltimore, Washington metropolitan area.

I'm awaiting delivery on a Pass Labs X 250.5 for the Mini Ulfs (when they arrive) So far there has only been 1 tube amp used with DI's and it was disappointing compared to ModWright SS. If there is one amp I should have kept around for the Mini Ulfs it would be the Finale 3008 SET integrated. Hopefully I will get to hear them with a proper tube amp at some point.

I sold my Modwright kwa100se a couple of months ago but it sounded great with my DI's I just prefer my first watts better for SS.
Do you have the 100 or the 150.
