........the next giant leap in AC delivery integrity.
I have installed a Teknasonics C-5 vibration absorber to the PS Audio Lab ll power cable feeding my WAPMC AC regenerator which feeds my CD player and can tell U that this is THE most significant step forward in eliminating resonances from AC delivery to date!!
This is so good that I am bordering on bewilderment at the very prospect of it BUT I am willing to bet that it is THE best AC tweak I have run across...........................hands down :-)
Vibration elimination from power cords, more to come.......................

I have 'em all over the place. ;-)
BTW, Machina Dynamica sells a tweak to enhance the performance of these.
I went to the Machina Dynamica website but could not find anything relating to the Teknasonics tweak. Maybe U could point me in the right direction.
By the way, I also have come up with a mounting tweak that greatly improves the vibration transducing performance of the units when mounted to speakers/subs/component racks etc. :-)

At the moment, I have a C-5 sitting on a PS Audio Lab ll cable that has been routed into an L shape right before the WAPMC.
This gives the absorber unit more surface area to sit on than trying to "balance" it on the cable. I am trying to work something up that will allow very intimate/solid contact with the power cable.

From your post:
"By the way, I also have come up with a mounting tweak that greatly improves the vibration transducing performance of the units when mounted to speakers/subs/component racks etc. :-)"
I am going to use the C-10s on my speakers so I would be interested in any mounting tweaks you have experimented with. Thanks
The absorber tweak generally requires that U have a floor standing speaker but a bookshelf speaker on stands can still benefit depending on how the stand is constructed.
It also requires that U have carpet/padding in your listening room as will be made clear shortly. I am working on an application that will work with non-carpeted flooring but have yet to actually get a working prototype.
The absorber will be mounted close to the speaker/floor juncture with 1-5/8" course thread drywall screws, or deck screws, wound down into the carpet/padding approximately 1/2" out from the cabinet and depending on the absorber model, 3 to 5" apart. The screws should be making solid contact with the flooring/absorber.
I have found the best application method is with the absorber plates facing down towards the floor and the 2nd or 3rd plate out from the absorber mounting plate making solid contact with the screws.
In this mounting configuration, the absorber has solid contact with the cabinet and also has a very solid contact with the screws/flooring which then allows the absorber to transduce the absorbed vibration/energy with much greater efficiency. An additional absorber applied in the traditional fashion also greatly benefits.
If your speakers sit on stands that have enough surface area for the absorber to be horizontally attached to the base, then just repeat for that application.
I will try to post a pictural here shortly.

Forgot to mention, it's not advertised.It involves taking one Large DH Cone and using rubber cement to adhere it to the center/edge of the TeknaSonic damper. I have mine on C-10 units and am not sure about use with the C-5. Ask Geoff if you're interested.
I would love to know what your special mounting techniques consist of.

I use a Walker Audio resonance control disc on the C-12 that is attached to my HSU Research subs in the same fashion as the DH cone.

See my reply above for details.

Audio cords and cables may be more or less flexible for side-to-side motion, but are very stiff along their axes. They will transmit vibration into equipment unless carefully dressed and supported. The bigger and stiffer they are, the more effectively they will transfer axial vibration into equipment.
Cords and cables should be supported as if they were components in themselves. Proper support will not add vibration modes, and isolate the cords or cables from wall or floor vibration. Damping is good as long as it does not simply change the effective mass and move the resonant frequencies around.
Kenster:
From sites selling the item: The C-5s attach to the rear of the speaker via magnetic pads, converting mechanical energy created by enclosure resonance to heat energy.
So I was wondering how you "connected" them to a power cord. Are you using the magnets near the cables? Also from pictures they seem to be sheets. Please tell us more of how you actualy implement. I feel that the Oyaide WPC-Z outlet cover changed things a lot in my system most probably due to vibration elimination.

At this point in tweaking, I have the C-5 just resting on the Lab ll power cable and have not implemented the magnetic attachment pad yet. As U may know, the PS Audio Lab ll cable is a very substantial power cable weighing in at 1 lb. of copper per foot of cable.
I have the cable positioned/routed in a sharp L shape turn right before the WAPMC and have the C-5 resting diagonally across the "L" which at this point is not making an intimate contact with the cable BUT it is having VERY good results with regards to sonics :-)

Hmm........Let me make sure I am clear on this.
You are claiming that by dampening a power cord feeding a power conditioner that then connects to your source you have made a significant improvement in your system?
"You are claiming that by dampening a power cord feeding a power conditioner that then connects to your source you have made a significant improvement in your system?"
Yup :-)
And just to be even more clear, the WAPMC is not a power conditioner but a precision AC regenerator. Also, the CD player is the only source in the main system.

What sort of improvements?
What is now different or better?
The biggest improvement was in the palpability of the instruments along with greater PRaT.
Also, it is like a photograph that was slightly out of focus but now is sharply defined with crisp image outlines/stability.
I would classify the change as much better rather than different. Of course, with a smaller/different power cord, it might be more difficult to implemenmt the absorber but I'm working on it :-)

Interesting. You never know in this hobby what might make a difference.
These things discovered with a hint of information, a handful of thinking and a bucketful of experimenting operate at the edge of what we know.
Especially for those of us who are not physicists.
The point is that it is possible to effect these thing.
In a different system, on a different floor it may be a different result.
Damping cables does not need a huge investment to see if it makes a difference in your system. Then you cans tart honing in on what seems to work best.
The more I try these things the less I criticise other people's findings.
You could try passing the cable between 2 sandbags. That could remove vibration and convert it to heat. It would also act as a cable riser.
I may try this this week myself...

I got 'em at Music Direct.

They are marketed as resonance contol devices for speakers. If they work on power cords (and here some pictures would be appreciated), they might be useful in other locations too: rack platforms come to mind.
To quote a great American: "I'm all ears". Tell me more.
Yes they R marketed for speakers but I have them applied to rack shelves, ASC quarter and half rounds and a myriad of other locations and have found that they provide a very useful reduction in vibration distortion.
Try a C-10 on top of your CD player..................:-)
Cheers
Shoot me an email if you will I have some questions for you.
Thanks
