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.

The Jolida Fusion Preamp is phenominal for the price. Lots of gain and really musical. Has XLR out but don't think it's truly balanced but not sure. 
In this price range a number of knowledgeable listeners are very impressed with the Don Sachs preamplifier. An excellent used option is the Atma-Sphere MP-3, very high caliber product. 
Another highly regarded 6SN7 preamplifier is the Dehavilland Ultra Verve 3. Should definitely fit into the desired budget rang if used. . Their Mercury preamplifier is also held in high regard.

@porscheracer,
Why not the Linear Tube Audio MZ2-S which has received high praise by Teejay and others here?  Also, it is below your budget.
@porscheracer  One which hasn't been mentioned, and is one I strongly considered, is Backert Labs.

If you are open to solid state, you may also consider the SST Thoebe II.
