If a power supply is struggling to keep that out of its DC power rails the equipment is very, very seriously flawed!
Most high-end audio gear has audio bandwidths extending to maybe 100kHz or so, and this cable introduces about 2dB of 'rejection' at that frequency. I can think of many ways of achieving far better rejection in the PSU than that at those frequencies and in far more cost-effective ways!
And the use of linear scales is wholly inappropriate and grossly misleading!
Usefully, what the plots do show is that a conventional mains lead is entirely appropriate and fit for purpose!

I don't bother going to those, much prefer Remote Viewing them from the comfort of the pub.
