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.

Your Rotel integrated will drive the 4 ohm DI's with ease.  I have not heard the Focals but will say the bass on the DI's is very nice.  Tight, clean (but not lean), and nicely extended is my take.  Do they take you into subwoofer territory?  Not in my room, but others would never consider subs.
Just pulled the trigger on the MZ2.  Went with the stock PSU, which I can upgrade to later for the same price.  Plus, according to Mark, the Absolute Sound and Stereophile reviews were based on the stock PSU.  It will replace a Rotel RC-980BX (my first pre), which I purchased in '94.  Should be a massive difference and let my A21 and DIs shine. 
Congrats treebeard, I think you'll be VERY happy with the mz2. It's a remarkable product. I would definately suggest that you try some NOS tubes as the MZ will reflect the character of the tubes used. My fav combo is Tungsol round plate 12sn7's with Sylvania gold brand, gold pin 12at7's. Have fun with it!
Larry the problem before they breakin at Audioarchon place , they are sold.iam interested to hear them too. Since I have the impact monitorupgrade I will have a bit of idea where the DI Se are.will see if I will have a chance to hear them..Iam looking forward to buy the ULfs too...
mac,
How are things with your new 300b?  Do you know what output transformers he used in your build?
You've listened to a number of amps.  What does the 300b bring to the table that your other amps did not?  Do you feel, driving the DI's, there are some types of music in your collection where you are less impressed?
