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.

@corelli  It's Scott Sheaffer's Found Music 2A3 

There isn't much information online regarding it, but there is some here, including pics:

https://www.whatsbestforum.com/threads/found-music-2a3-amplifier.4279/

And some tech info, below:

"These are 2-stage direct coupled single ended triode design. Rectification uses mercury fullwave rectifier tubes
Driver circuit is powered and operated as a dedicated amplifier by itself, rectifier is 82 and signal tube is 7A4
Output circuit has own power supply as well rectifier is 83 and tube of course is 2A3
PS and bypasses are Jantzen and Jupiter. UX4 sockets are Audio Note silver and ceramic. The amps are wired throughout with UPOCC copper. Magnetics are nickel from Intact Audio (Dave Slagle).
Output with the JJ 2A3 tubes that are stock with it is just shy of 3.5 watt into 8 ohm. The amps are made for a 6-9 ohm impedance."

@charles1dad  was instrumental in his support and advice, without which I would have been lost in the woods as this is very new territory for me. Thank You Very Much, Charles.

Wow.  That is one serious effort David.  I'm sure when you get that system together it will be special indeed.  I'll be curious to see what preamp and speakers you end up going with.  And I'm sure your SE's will get to spend some time with this amp as well.  Keep us posted.

David,
you have acquired an acknowledged , all out assault and state of the art 2A3 SET  amplifier. It is designed,  implemented and built to the uppermost level.

 Given your stated objective and purpose/intentions with this amplifier I think you are going to find it stunningly good  with the appropriately chosen  speaker match. Congratulations on getting this world class  power amplifier.

Very cool amp! I like the over built design and direct coupled driver. Be aware of Mercury rectifiers, they're far more dangerous than the liquid mercury in older thermometers and if broken will quickly spread a fine mist around the room (more so when hot). I would never want to break a mercury rectifier tube in my living room, that's the main reason they were foregone for the more common 5U4, 5Y3, 5AR4 rectifier tubes.
