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

Thanks.

@kdude66 - Congrats Kenny! Seems like a very nice amp.
Why was the 6sl7 a better driver tube than a 6sn7? Does it have something to do with using the 2A3-40?

I'm trying to picture "This amp was built in a standard Hammond case with a cage covering the tubes and the case was painted sapphire blue with a black case" So it's a black Hammond case painted sapphire blue? Can you post some pictures of your overall system?

Hey Kenny, I really appreciate the kind words on my build and am glad that you’re happy with your amp! Perhaps I can shed some light on the driver tube: My test preamplifier has up to 35 db of available gain (using 12AT7’s), and in my testing I found the 6SN7 would drive the 2A3 easily- with lots of headroom from my preamp’s volume control. In Kenny’s system, his preamp is configured for a lower gain structure that needed to be pushed higher for the same drive from the 6SN7. By substituting the 6SL7 (raising the gain of the driver), it allowed his lower gain preamp to reach the same overall drive available to the 2A3. Both the standard 2A3 and JJ 2A3-40 have the same input requirements. Aric

@kdude66 why did you change the DI Wilfred to eminence and which model did you chose? What was gained? Tighter bass response? Hmmm. Thank you Kenny!

Thanks Aric.  The MZ2s needed more gain to properly drive the 2A3 so the 6SL7 was the better fit.  Makes sense.
