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.

@kdude66   Kenny, thanks for sharing your impressions of the Aric Audio 2A3 amp, built to your specs.

Did you use it with Preamps, other than the LTA MZ2S?  If not, it would be good to get a read from you on synergy with the LTA vs other preamps.

Also, are you planning on pairing it with another set of speakers to get more insight into the amp?

Thanks.

... regarding the preamplifier gain issue, 35 db is far too much for virtually any audio system to utilize. You’d literally have no range of the volume control i.e. one click above the 8 o’clock V.C. knob and it’d be too loud even in systems with very inefficient speakers.
Sorry, but you are completely mistaken. There is no inherent correlation between the position of a volume control and the actual output of a preamplifier.  Different volume controls have varying tapers, and it's the taper that establishes the link between the control's position and the output of the preamplifier. You can design a control's taper to set the output anywhere you like along the control's rotation.

Cleeds, I wouldn’t by any means say that Charles is "completely mistaken." While it is of course true that there are differences in the taper characteristics of various volume controls, it is also true that, as he said, "35 db is far too much for virtually any audio system to utilize. " And I would add emphasis to the word "far," especially in applications involving digital (as opposed to vinyl) sources.

And while "you can design a control’s taper to set the output anywhere you like along the control’s rotation," a preamp which provides 35 db of gain but has a volume control taper that results in the control being positioned in the area of say 12 o’clock when used by most listeners in most systems would be an unusual design to say the least.

Hey guys, just a generic note on my test preamp. I use this as a unit for my bench only (it's not something I design for consumption), and it has a variable output level as well as input control that can reach up to 35 db (generally 35 db is not used in everyday testing). I was simply stating that using that preamplifier, I was able to get plenty of drive into the 6SN7 driving the 2A3. Using a lower gain preamp, the 6SN7's can still be driven, but needed a bit more volume on the preamp to do so. The 6SL7 simply has more gain in front of the power tube- needing less preamp drive at it's input.

That was the only aspect of his post to which I responded, Al.  Many audiophiles cling to the misguided assumption that the actual physical position of a volume control in some way correlates to actual output power. You certainly understand that a volume control that is half-way between full-on and full-off may drive an amp at half-power, quarter-power, or nearly full power, or anything else. There's no way to tell without actually measuring.

I don't argue that 35dB seems like very high gain for a line stage preamplifier and it isn't clear to me what, if any benefit, such high gain would offer.
