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 .

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.

I was also wondering about what @adg101 said,
Curious why not set your amps behind or beside your speakers and run a balanced cable from your preamp to your amps if you have a balance preamp? Yes, your amps are going to be out in the open but they’re beautiful.
Since you have monoblocks, you could reduce the speaker cable length to nearly zero -- and it's the speaker cables that carry a high-level, low-impedance signal to a reactive load. A long balanced interconnect of the right type will have next to no effect on the sound. Whether you like the result is another matter, but it's the path I'd be likely to take with the sort of gear you have. It could be a startling improvement.

My gear is significantly less costly, but I do use 25' balanced interconnects and short (5') speaker cables with a stereo amp. After doing an extensive comparison, 3 very experienced audiophiles (two are professionals) and I concluded that interconnects made with Mogami cable were far less colored than an "audiophile" pair with MSRP 22x as much.
