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.

@333jeffery - Someday perhaps! I think my first 1kV triode will likely be the 805 or 845, as I've got the basics on a design down for those. The GM70 is very similar, but in all cases these designs are not cheap to do right. Using over 1,000 volts and requiring 2-3 stages to drive these huge tubes is a very deliberate complexity. The 300B, and 2A3 are next in line as far as needing low current, high voltage swings. The easiest tubes to drive are the Pentodes or Kinkless Triodes (KT88, KT120, KT150). The general rule is the less stages in the signal path- the easier it is to make an amp that sounds transparent in my opinion. 
Drat! Too late to edit. That should’ve been "as far as needing high current (low impedance), high voltage swings".
Aric,
Thank you for your clearly explained reply. I certainly realize that there’s more than one way to design and  build an excellent sounding amplifier. I do like exposure to various perspectives and continue to learn from knowledgeable builders such as yourself.

@charles1dad  Anytime! I appreciate you asking for my insight on the subject. Best, Aric
mac,  I must say you've got a lot of new toys coming your way!  You'd  think it was Christmas or something.
I'd really like to see the chassis Aric is using.  Any pics?
