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.

Hi Kenny,
Thanks for the detailed reply, you are definitely on the right track. My 300b Frankenstein has interstage transformers as does my Coincident Statement Line Stage (101D tubes which are DHT). I can see no reason why your 2A3 which is also DHT could not use an interstage transformer as well. Going this route and with mono block construction sounds like a fabulous idea. Bill (Grannyring) could suggest some excellent choices for capacitors and wire, he has tried "many" over the years. Your Double Impacts are going to sing to the heavens 😊

Great build Kenny. Tremendous pricing also. Those  magical Duelund silver foil bypass caps in the coupling positions would do wonders with the fine Audyn caps. You know that already. 

I think he uses electrolytic caps in the power supply? Anyway to use film? Yes they take up more room and may not be possible. I love the Clarity TC line, but even Solen Fast Caps will sound better than electrolytics. This is an important area for consideration. Film caps in the power supply do make a difference.  

Not sure if the design uses bridge rectification? Regardless, using the low noise, fast recovery types adds very little to cost.  

Resistors also impact the sound. I really like the SHINKOH - Tantalum sold at Parts Connextion. They are beautiful sounding. Many DIY guys love them also. Well thought off. 

Fun stuff! Enjoy.....

Kenny,
I appreciate the fact that you want to adhere to a specified budget for your custom made amplifier.  I do agree with Bill's recommendation of using film capacitors rather than electrolytic capacitors in the power supply if this doesn't disrupt the budget. This is amplifier can really be a first rate product with specific choices/decisions.

Charles,

Thank You for your recommendations and the info on your well enjoyed Coincident gear.

Grannyring,

Thank you for your good ideas coming from all your Diy and modding experience.
You are correct the pwr supply will have electrolyte caps at this price point and will need to addressed,maybe could use film bypass caps,
the amp will be built in a small 12x7 case so probably not much extra room.

When I do get it I will send you some pics and see what you think will be best to do.

Kenny.
