Did anybody care to try it?
This LossLess idea do sound interesting…. if it works…

"In the DFPC Original, we utilize the naturally accurring skin effect to its own detriment, in order that the cable be inhibited as an antenna while connecting the gear with the power grid or power filter / distributor. The development of filtering via a purposefully lossy skin treatment has proven a great success with many satisfied users worldwide. We incorporate this same skin treatment in the DFPC Signature. In addition to this, we implement further skin treatment featuring overlapping high frequency absorbance and reflectance spectra to maximize this high frequency noise suppressing faculty. The result is not simply a "poorly conductive" skin, but one which combines poor conduction with refined and highly tuned high frequency spectrum manipulation to inhibit electronic noise more than in the Original and to bring the nature of music more to the forefront. Something as simple as a cheap transistor radio thus becomes an almost holographic sound source, due to lack of noise normally associated with electronics.
Noise always works from the top down. That is to say, low frequency noise does not really exist, apart from the 50 or 60 Hz fundamental power frequency, without which we can't power our equipment. The harmonics (going up) from 50 or 60 Hz exist because the power encounters non-linear loads, because it goes through transformers with hysteresis, because it was created with generators which have non-perfect flux distribution, not to mention things closer to home which buzz and hum, adding harmonics to the 50 or 60 Hz. These are all harmless to your audio quality, as they are effectively filtered out by the filters built into your audio gear's power input electronics, which is exactly what they are built for. But going from the top down, we have the real source of noisiness which intrudes upon the natural sound of music. This is the non-linear, non-predictable interaction of the audio signal or digital clock and data retrieval system with high frequency radio and even light waves. Not all light is visible, and most of it is in bandwidths which we cannot see, but when you add it all together, the spectrum and energy is enormous and has profound influence on the quality of the resulting audio signal. The reason: in an electromagnetically non-controlled environment, you will always have haphazard electromagnetic ambient fields at all frequencies going in all directions at all times. Indepth discussion of this can be found in my discourse on the LessLoss Blackbody."
I do feel that many comments they made in here and across the site are very questionable and some of them are just false but still the concept of UHF filtration via skin effect might be interesting if to know how to use it. Why LossLess do not publish the actual data of the filtration is behind me. I want to see how many dB and at which frequency, I what to see how the cable length impact dB/frequency ratio. If they clams that it is a filter but do not give the curves then does it makes the whole claim very strange?
If it work then I might be interesting to try it after PP2000. They have 30 days money-back do I need to try? Did you see anybody try it and published the curves of HF filtration?
