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.

Kenny, 
The LTA M2Z-S  is such an obvious choice I didn't bother to mentioned it in my posts earlier.  I just assumed awareness of it given the multiple times its been discussed in this very active thread. So I thought I would offer a few alternatives.

Brotw, 
The Pass Labs XA 30.8 and the LM 508ia would be a compelling comparison.  Both are considered to be excellent yet presumably with distinctly different presentations.

Charles,

No worries at all,It's a good thing to have choices and quite a few top notch preamps have been mentioned.

@porscheracer,

Over the the years I have had the opportunity to own and listen two many top flight preamps. Far too many for me to list, but units like the Tom Evans Vibe & Pulse, CJ LS16 MKII, Audio Note M6, Supratek Cortese, TRL Dude, and many others. I sold gear for several wealthy audio friends giving me access to great pieces regularly. Fun!

I say this because one preamp in particular always stood out as exceptional. It is the Audio Valve Eklipse. We had a shootout with this preamp and an Audio Research LS27 and all of us easily preferred the Audio Valve. It is an amazing sounding tube preamp that flies under the radar. You can buy one new for around $4500 and used for $2500-$3000 when they show up. Not sure if this one is still available;

The seller recaps the sound of this unit nicely in his listing. No need for me to add more as he did a great job. If I needed a preamp today, then I would most definitely seek out a used Eklipse. Hard to find used but they do come up once in a while.
