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.

Another variable regarding power amplifiers is their sensitivity as measured in volts would influence the correct gain level of the preamplifier. Some amplifiers can be driven to full output with 1 volt or even less (My amplifier sensitivity is 0.7V). Some amplifiers are less sensitive and may require 2 or 3 volts to drive to full output. The Pass Labs may be in this latter category.

Exactly! I tend to want to design with some headroom in mind as there's nothing worse than running out of gain while the amp is just starting to open up. Like a governor on a hot rod.... No bueno!

Can't wait to see pics of the Motherode Aric. I don't know what a tube regulated power supply is but it sounds cool to me. Can't ever have enough tubes if you ask me. 

I wish I understood how gain affects how amps and pre amps worked together better......that's one of the reasons I had Aric build my preamp and amp together, to avoid having to worry about such issues. I know this much I can't turn the volume knob much over 9 o'clock without it become too loud for me. 

Brian, you're right the preamp and amp Aric built me sound fantastic......if only they had a cool name like Motherlode! Lol. I'll call the preamp Moe and the amp Foe. What a pair they make 😀

On a different note, great call teajay, Steve Winwoods Greatest Hits Live is a keeper. Ben Harper and the Innocent Criminals is another new fav of mine.

Tom,
I don’t doubt for a moment that your pre and power amplifier combo sound wonderful. If you can’t use your volume control much above 9AM it does suggest that there’s more gain in your system than you need. Ideally you want to be able to use the volume at a higher setting as this allows more VC range flexibility and "finer" gradients of volume adjustments.

My initial Coincident Statement Line Stage had 18 db of gain and VC was very limited to 8 to 10AM. I sent it back and had the gain deduced to 10db. As I stated above this provided a much broader (useful) range of the VC. You can try Rothwell attenuators (plugs in RCA receptor between the preamp and amplifier. They’re available in various levels of db reduction i.e. 4,6,12 db. They’re pretty effective. Harrison Labs is another brand to consider.

Tom,
If your 300b amp has similar sensitivity to my Frankenstein and If your Concert Fidelity DAC output voltage is 2 volts or higher (My DAC is 3.1V) and with your 94 db speakers you don’t require much preamplifier gain.  I've been down this road 😊.
