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.

Tom,
If your 300b amp has similar sensitivity to my Frankenstein and If your Concert Fidelity DAC output voltage is 2 volts or higher (My DAC is 3.1V) and with your 94 db speakers you don’t require much preamplifier gain.  I've been down this road 😊.

Charles,
I'll have you look at it soon. I'm hoping to have the kitchen back together this weekend after having to rip drywall out to repair plumbing ( being under the weather today didn't help) I'll finally be ready to have you over for a listen and we can discuss then. Right now there's no way I'd get to 10 o'clock on my VC without earplugs. Never thought I'd have to think about lowering gain with an 8 watt amp.....lol.

Tom,
Power (watts) and gain are two different issues.  Again your amplifier may have higher sensitivity than the typical power amplifier and this affects overall system gain requirements. Your preamplifier may be a high gain design (>16 db).

I believe I had the volume up to between noon and 2 using a streaming device as the input before Tom’s amp started soft clipping, which was on 90 db speakers, on the 8 ohm taps. It also depends on the level of the recording. Les Zeppelin needed to be raised much higher than say Pearl Jam, for instance. The entire system sensitivity and desired level of listening comes into play heavily for sure.

I should have some pics up maybe as early as the weekend, depending on what the lady has in store for us when she comes up. And Tom, you also have a tube regulated power supply using those OD3 regs on either side of the transformer cover :-)
