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.

Hi Charles,

Micheal's preamp and amplifier are VAC tube gear.  Yes, it will be interesting what his experience will be.
Forgot to share the following:

1)  Ran the experiment of using the Micro-ZOTL as an integrated amplifier driving the Ulf's.  It was great, just like on the DI's with the added benefit of more headroom/volume when needed!  Again , this shows that the Ulf's are more efficient then the DI's.

2)  Took the Micro-ZOTL out of the reference system and replaced it with a very good tube based preamp that I use in my second system to drive the 2A3 amp.  This validated my assumption that the synergy between the Micro-ZOTL ( the powerful macro-dynamics-see through transparency-3D imaging-overall speed) and the Triode Lab 2A3 amplifier(gorgeous color/timbres-"meat on the bones" imaging) is what leads to the best combination for my ear's driving either the DI's or Ulf's.  The system minus the Micro-ZOTL lacked the dynamics/life and sounded soft and took the aliveness out of the listening experience.

I wish all you DI's proud owners could hear this combination in your system, it will play at very high volume levels, is totally grain-less, accentuates the aliveness of the DI's/Ulf's, vivid 3D imaging and produces the most beautiful tonality/colors I have ever experienced.  
Terry,
It seems that the Triode Labs 2A3 amplifier/Ulfberths impressed your three experienced visitors in the large listening space. Nonetheless I suspect  the 3 watt power specification is a formidable barrier for "some" to overcome regardless of the touted sublime sound quality.
