Tekton Design's new THE PERFECT SET equals "goosebumps time"

This speaker company intrigues me. But man it seems you either love it or hate it.

dcevans,
sorry I wasn't around yesterday to answer your tube questions. So, here goes: first, a question, do you have the most recent Dynamo or the original? I have owned both. The original Dynamo is a sweeter sounding amp though less robust in power supply. The original uses 5U4G rectification or equivalent and the newer model 5AR4/GZ34 or equivalent.

My original Dynamo SE sound best with Gold Lion KT-77s; they were compared to Psvane black 6CA7-Z (el34) which I used initially for about 6 months. Then I conducted a tube shootout. NOS Siemens el34, Tung-Sol el34s, New Mullard el34s and Gold Lion KT-77s. My results matched reviewer Steve Smith's results closely. Order of finish: KT-77s Psvane, Tung-Sol, Mullard, NOS Siemens.

My 6SL7 choice is either RCA Red base 5691 or NOS Sylvania 6SL7WGT. Rectifier tube best NOS GEC 5U4G, NOS Mullard CV378, RCA 5U4G or NOS Mullard 5AR4.

Along the way I modified my original Coincident Dynamo SE at the advice of Yazaki-San. Read about this gentleman on Jeff Day's Blog now on Positive-Feedback. Yazaki-san recommendations included strengthening the power supply, use of better capacitors, NOS resistors, rewire of internal wires with Old Western Electric tin-plated copper. 

You might consider contacting fellow Agon member grannyring for a loom of Dueland powecords, interconnects, speaker wire...all of which work great with the Coincident and my current Tekton speakers, Lore and Mini-Lore. I also use these wires with my DeVore Orangutan 0/96 Leben. Best, mikirob 

I will private message you. Didn’t mean to hijack this thread. Thanks  Dave

The newest Coincident Dynamo seems like a cool amp, at least based on the recent review I read somewhere, and it’s gorgeous...I considered a used one when shopping for a single ended amp (it was the older version), but my "bought used 3 months after its birthday" Dennis Had Firebottle HO (yes, it’s a HO...says so right there) won out and I’m happy with it....a few more watts. Defy the manufacturer and stick a pair of Gold Lion KT77s in that Dynamo! Do it, do it now!

I’m slightly curious about the "impedance curve" of my Heresy IIIs, but only slightly, and mainly due to Mapman’s comments...damn him! (kidding...don’t report me to the moderators)...the Fritz Carrera is 87db efficient and the only thing I’ve dug up about its "benign" impedance curve matches what I’ve read about the Heresy III, but I didn’t dig that hard...8ohms nominal, 6ohms minimum...and the Fritz is exactly 3 times the cost of my Heresy IIIs and 11db less efficient (!), which makes for strange if not unlikely bedfellows. Those things would likely suck the mojo out of my Firebottle during a crescendo or pretentious jazzbo outburst! One of the things I like about the Heresy IIIs, other than the sound, is they’re somewhat unique for a modern speaker...I was kind of bored with the "woofers and a tweeter in a box" design of 99% of what’s out there, needed efficiency with my Had amp, have been very happy with the sound of the anachronistic fat little things, and get uncontrollably emotionally defensive when their worth is questioned...*sniff*..."leave Brittany, uh...I mean MY HERESY IIIs alone!"

I have historically preferred high end 2 way standmount speakers.  They disappear in the room, throw a big soundstage, and offer high value IMHO. For the type of music I listen to, a lower frequency of 40 Hz is all I require. The Fritz Carrera caught my attention roughly 3-4 months ago based on highly positive reviews by attendees at an audio show ( Capital Audio Fest I believe), and it’s solid base extension to 35-40 Hz. That they are sold direct by the manufacturer with very high quality parts and the offering of a home audition before committal, and learning that they have a smooth/benign impedance curve that allows for lower wattage tube amplification, only heightens my interest.  Yes, with stands they are almost double the cost of new Heresy IIIs, BUT they are less than half the cost of the Joseph Audio Pulsar — a similar highly desirable speaker that also has a SEAS driver, similar frequency response and benign/smooth impedance. 

I had wondered when you might weigh in Wolf haha. As I mentioned above, my critique of the Heresy was premature.  The stock Chinese tubes that came with the Coincident Dynamo 34 SE mk2 are casting a somewhat bright sound with these speakers I think, and that is something I can modify to suit my taste. One of the reasons I wanted to try a tube amp in the first place. My system currently lacks the warm lush saturated midrange that I heard in the late 70s-early 80s at a dedicated audio store in Rapid City that unfortunately ceased to exist many moon ago. There I heard large Klipsch speakers being driven by Mcintosh tube gear playing Sheffield Track records — a very memorable sound.  If I can create that midrange of yore with my current system, I can live with the 58 Hz extension— or buckle and get a small 8” subwoofer.  

By the way, I like the fat/squatty profile of the Heresy — and it was another reason I chose it: I don’t have to worry about my dog or a future grandchild knocking it over.
