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.

Charles, Thank you for the explanation and specifics.

How would you predict the sonic outcomes (in differences) based on the 5 design differences you list?

Thanks.
@333jeffery  Thanks for posting the video. The clarity is so much better with this one and the sound as well. Those Carver (?) amps  look sweet...are you still using them or have the BHKs taken over? 

Look forward to hearing how the Allnic and BHK preamps compare!
@porscheracer  Any finalization on the preamp choice, now that you've received a number of suggestions?
@snopro   Thank you so much for your honest feedback on the MZ2S' performance for you. It's very helpful and I for one am glad you posted in the face of very strong support for this preamp in this thread. 
Thanks everyone for your kind words and being civil about different opinions!
Charles, you are to kind and seem like a true gentleman. Your insights are highly regarded on this forum, my friend.

Here's my take between the amps, IMS.

The Franks are all about tone, texture, and timbre. They are wonderfully open and very natural sounding (organic) with nice extension and dynamics. No soft, syrupy, highly colored sound here. Very powerful sounding for only 8 watts. Excellent with Jazz, (about 80% of my listening) vocals, and acoustic music. Very good with just about everything else. They are wonderful amps especially with good 300b tubes. My favorite are Takatsuki TA-300b's very refined and well balanced. Just a wonderful amp!

The Pass XA-30.8 is a brute in silk gloves. They are 30 watts of pure class A, but really are rated very conservatively. It weights about 85lbs.
The Pass goes lower and is more dynamic. The soundstage actually is a little bigger with very nice layering and separation. Its not as open and emotionally engaging as the Franks, but comes pretty close. That is high praise for it being a SS amp. Highly recommended for anyone who doesn't want the hassle with tubes. My speakers have 16 woofers altogether and the Pass really take control of those woofers, which the Frank's can't quite do. They are very smooth and grainless. If you enjoy rock, pop, and amplified music they do that very well. it also sounds wonderful with Jazz, vocals, and acoustic music just not as good the Franks.

It's nice to be able to enjoy both and I very much do, my 2 cents.
