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.

Am thinking of giving a tube amp a try and have been looking at the primaluna dialogue premium -- because it has substantially better specs than other units. Could not find out from them the class of their amp although it is push-pull. Would not consider anything other than class A.
Craig, the Dialogue Premium and Dialogue Premium HP power amps operate in class AB, aside perhaps for when they are putting out low power levels.  That can be inferred from the relation between their rated maximum output power capabilities and the specified current ratings of their mains fuses (as indicated in their manuals), assuming a reasonable margin (e.g., 2:1) between the fuse ratings and the actual AC current draw that is anticipated.

Given the maximum output power ratings of those amps, their mains fuses would have to have considerably higher current ratings than specified to support pure class A operation.

Thanks, Al. Have a very large room open to 3 other rooms and do not believe that a tube amp is realistic in this scenario.

In my experience the vast majority of tube push pull amplifiers are class AB circuits. There are a handful that are pure class A.


Lancelock,

Synergy is definitely a factor in many circumstances. In my case using the same brand line stage and power amplifier I'm convinced makes a difference for the better.

Charles1dad,
You are right; your comment prompted me to remove the Micro ZOTL from another system and connect it to the Dynamo. Better than slight improvement. Very nice improvement. Like Lancelock stated, "heavens opened up, angels sang." I really can't explain why I though otherwise. Probably not listened to the Micro ZOTL with Dynamo in too long a time; still, the Dynamo is very good on its own. And yes, the Dynamo responds extremely well to tube rolling.

I should also mention that my Dynamo has upgraded caps and resistors /power supply based on suggestions by Yazaki-san, the designer/mod-maven from Jeff Day's blog.


Charles, you are favorite poster along with grannyring and some others, such as Almarg. Always  respect your opinion and what you value in music. Best, mikirob

Craig59,

Craig, the Dialogue Premium and Dialogue Premium HP power amps operate in class AB 1 configuration and have no pure class Output even at lwr pwr.They are configured to operate in triode or ultra linear modes but the output pwr ratings with different tubes all make sense to me that they are ab output.

But like you said your large room needs much more pwr.

Mikirob,

Very interesting to hear that you like the MZ2S paired with the dynamo made that much a difference.
I just love my MZ2S and have paired it with several different amps just to try it.I will be getting a Zotl 40 next Tuesday and I will use Mullard XF2's that I already have in my collection,should be a very nice pairing from what I'm reading.

Best,
Kenny.
