Kimber 12tc incompatibility with ayre my-r twenty

I  am having a problem I have been trying to figure out for the last month . I think I have an answer now . I would like to know if anyone has had any similar experience .
i recently upgraded from an all parasound system with jc-1 , jc-2 , jc-3 to an all ayre stack with kx-r twenty , mx-r twenty, Qx-5 twenty, px-5 and cx-5. I retained all the kimber cables and speakers kef blade 2 speakers that I had.
The sound was phenomenal, so romantic so clean , amazing vocals , so powerful at the same time . I loved it, gave me goosebumps.
But the power amp would turn off to standby when I played it real loud .
i reached out to ayre. They have the best customer service in the entire audio business. Amazing group of people who love music and their products and stand behind their products. We tried a lot of trouble shooting and finally figured it was the kimber 12tc speaker cable as the culprit. With cheap Best Buy speaker cables the system functions flawlessly. They felt it had to do with high frequency oscillation or rf as the cables are not well shielded.
has anyone had similar experiences
I have reached out to kimber to get their input.
thank you .

Cardas recommended clear reflection internal biwired configuration 30 ft as an ideal capacitance load for the amp and tonal balance match for the blade 2 speaker.... looking for more advice

Electrical parameters aren’t specified for Clear Reflection at the Cardas site, but what leads me to question that recommendation is that generally speaking I would expect a biwired cable to present approximately twice as much capacitance to the amplifier as a similar non-biwired cable. And possibly somewhat more than that in the case of an internal biwire, depending on its construction.

Although in looking at pricing for the cable at The Cable Company site it appears that while a 30 foot length of that cable will cost around $8K for a stereo pair, specifying "biwire" appears to add only $200 to the price, and that is regardless of length. Which leaves me puzzled as to what the difference is between the biwired and non-biwired versions of that cable. Or would the approximately $8K + $200 be multiplied by 2 for a stereo pair of biwired cables, bringing the total to around $16K? That doesn’t seem "clear," pun intended :-)

@audiotroy ,
Sorry, but I respectfully disagree.
Given the vast spectrum of AQ cables, I think judging the Element series and not the others, is a disservice to AQ.
If the KEF Blades have such an extended 'top', I would be afraid of listener fatigue after an hour or two.
@OP,
I would contact AQ and get their take on this. And, yes, they do answer the phone.

A while ago, I collected RCL values for a bunch of speaker cables. Many manufacturers don’t provide them, so mine is a short list.
All the cables had low resistance, < 0.005 ohms/ft.

The highest capacitance were the Goertz MI-2 Velocity (317 pf/ft), Audience Maestro (168 pf/ft), and Kimber 12C (151 pf/ft).

The cables with low capacitance *and* low resistance were the Belden 5000UE and 5T00UP. Both have about 0.15 uH/ft inductance and about 25 pf/ft capacitance. They are available from Blue Jeans Cable for very reasonable prices, and might be worth a try, given you have a long run. With 30 ft, I definitely would want low R, C, and L.
(I am using Kimber 4TC, but the run is only 5 ft. The 4TC runs 41 pf/ft.)

I mis-typed when I wrote: "The cables with low capacitance *and* low resistance were the Belden 5000UE and 5T00UP."  I should have said that they are the cables with low capacitance and low inductance.
