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.

@teajay   Terry, terrific review and a great read. I had a great day and a half reviewing my system and the 30.8 shined. If the XA-25 is superior with the SEs, I'm not sure I'll be able to handle it! : )

Terry:

Enjoyed your review of the Pass Labs XA-25; this is an amplifier type/price point I have been searching for. Purchased the DIs, btw, partly on the basis of your original review (seems like a longtime ago, doesn't it?).

The lack of a balanced architecture has me worried, however. You mention this in your review but am wondering if you could expand on that architecture and consider what, if any, pros and cons this input style has.

Thanks.

Hey craig59,

As you know many amplifiers have XLR inputs, but really are not truly balanced designs.  The beauty of the XA-25 is it's use of only two transistors per side and the tremendous power supple which drops tons of current when needed.  So, I find no downside at all, and historically have never run XLR cables in my system even when I was using the XA-60.8's which are a true balanced circuit design.  Less is really more can be heard in a great SET design and in Nelson's new simpler circuit.  
Hi Terry,
I haven’t read your review of the Pass Labs XA 25 but will do so. If this is a simpler circuit design with fewer part count. I could certainly believe it sonically exceeds other Nelson Pass efforts. I can understand his decision to go with minimalist single ended rather than balance circuit. Only 2 transistors per channel? He does seem to have much genuine passion for these type of amplifiers.

For all the talk concerning balanced audio components I can’t honestly say that they sound superior to non balanced components. I can say that some of the very finest sounding systems I’ve heard were based upon simpler single ended be they tube or solid state. Based on Nelson Pass writings and DIY contributions I get the sense he leans in this direction for maximum purity of sound. Just my hunch. Balanced components do however have a large segment of happy advocates no doubt. .

Reminder modifications doesn’t always work, I prefer to stick with the way Erik design my tekton impact monitors. Be extra careful before jumping into it.He knows his speaker design why we end up buying them, and enjoying them.
