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.

This is, truly, an exceptional thread and it is buoyed by the quality of the regular contributors and the revolutionary nature of the DI.
This is addressed to Grannyring and any others with exposure to both class A and class D amps. Have recently had the experience of trying out a Nord Stereo UP Class D amp on the recommendation of several on this and other threads.
This was my experience. Initially, the Nord amp sounded just like a Yamaha receiver I have -- somewhat accurate but sterile and uninteresting. As it broke in, it became better in reproducing acoustical ensembles but still not of a very high quality. After shifting over to another OpAmp, the Nord did sound OK on orchestral feeds and I was planning on keeping the component.
Then, the left channel died and the unit was returned to Colin -- who did the professional thing and refunded the entire purchase amount. So, after a week of listening to the DIs solely with a Class D amp, went back to my Emotive mono blocks that have 35 watts of class A that does, of course, cover most of the volume levels with the DIs.
Was shocked at how much better the Class A amp was in two particular areas: 1. Tone weight and 2. vocal soundstage and accuracy. Tone weight was seen in particular with instruments such as the cello where the body and feel of the instrument came across in class A but not in D. Vocals were more prominently actually there and the accuracy of the singer was significantly improved.
With the class D amp, I felt there was a lack of volume and sometimes raised the level very high without achieving the sense of visceral presence.
SO, my question is this: Does the Lyngdorf 2170 accomplish the visceral sense of power lacking in the Nord description above?
AND, Grannyring, had the same experience in May of this year listening to the DIs at very high volume levels with the same sense of delight. Eric mentioned to me the potential danger of ear damage with very high levels and have adjusted my levels accordingly.
Just my 2 cents since I have experience with both. You won't find any improvement (at least to my ears) over the Nord One Up with the Lyngdorf 2170 minus the room correction. It should be mentioned there were some speakers that sounded better without room perfect. The effortless power of the Nord amp gives it an iron grip with most speakers. I did find the 2170 to be easier on the ears at lower volumes though. Pairing the Nord with a quality tube preamp can eliminate many undesireable issues. I have a friend using one with an EAR 868. Devialet does a great job of making a Class D hybrid amp that retains the qualities you mention with your monos. I went from the Lyngdorf to a Devialet D-Premier and the difference in sound quality was not subtle. I personally preferred Pass Labs and ModWright with the Double Impacts but that's just me.
At $16,000 the Devialet D-Premier should sound better than a amp at $4,000 -5k
Thanks for your input James.
James, did you use the 2170 as a total system or do you use an outside dac, amp, or preamp? Thanks.
