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 Aric,
Thanks for the additional information.  This custom made 300b  amplifier driving the Double Impact SE will be a fantastic pairing is my prediction. 

Do you have an opinion regarding electrolytic versus "film" capacitors in the power supply (filtration) and is one inherently better than the other ?

Jay, the speakers are 6' o.c. with the listening position about 8' from the speakers. 

Thanks for the recommendations Greg and Charles. I have some new CDs to look forward to Monday now.

thanks Aric, you explained the amp build far better than I ever could! There are many here that will understand the build much better than I as their informed questions will demonstrate......as Charles has already demonstrated.

Hey Charles, you're very welcome! With regards to filter stages, I am a believer in using good quality electrolytic bypassed with a high quality metalized polypropylene. To get a film capacitor of the correct UF ratings to effectively smooth ripple, size restraints come into play. Good low ESR caps can make for a very quiet power supply circuit. Aric

I also wanted to add that in any build I undertake, I like to maintain a "form flows function" approach (and also follow the KISS rule), by keeping all power circuitry towards the rear of the amp near the AC inlet, and all signal paths towards the front and/or out to the sides. Then find the average operational points of the tubes, and design around that. Use transformers rated for at least 33% more than the duty cycles of the circuits.Then the use of high quality parts come into play (the sum of the parts gives a synergy- much like the blend of a good recipe), keep wiring paths short (twisting filament wiring to cancel AC fields, shielding signal wiring wherever it may encroach a power circuit, etc.). Lastly isolate the chassis from audio and signal grounds and use a star/single point termination for the ground reference. I’ve found that maintaining all of these aspects in any build yields a reliable and typically a great sounding piece of gear.

Thanks Aric. Good stuff.
