Reviewing cables is not the most attractive part of audio reviewing. Cables have so much influence on the overall sound that it’s sometimes scary. For instance, unplug a cable—no matter whether IC or power—and plug it right back in. The sound has altered. We recall a review assignment in which we compared several interconnects from budget to outrageously expensive. That job was a nightmare to do properly. Another obstacle in reviewing cables and in this particular case power cords are accessories by way of a power regenerator, a LessLoss Firewall and passive LessLoss Blackbody ‘filters’. All these interfere and obscure the essence of the raw power cords in use. As the subject of today’s review is the ‘enhanced’ Signature version of the original Dynamic Filtering Power Cable, proper protocol demanded we return back to that cable and remove all accessories acting in the area of electric power conditioning. Hence the system was stripped of the PS Audio regenerator, the LessLoss Firewall and all LessLoss Blackbodies. Then all power cables were replaced with LessLoss original DFPC insofar as they were not in place already. After some sweat in the mines, the system ran five Lithuanian power cords for both powered woofers on the hornspeakers, the Audio Note integrated amplifier and the PS Audio Perfect Wave transport and DAC. For vinyl duties the Tri phono preamp could borrow the PWT’s cable to always leave the DAC powered up.


The only accessories left that might interfere with electromagnetic radiation in one way or another were the Acoustic System resonators. An upcoming article will compare these resonators to the LessLoss Blackbody and Ben Piazza’s Shakti Stone. Because the resonators work wonders for room acoustics and ours have been meticulously placed, we did not want to remove them from the listening room. Now we had the physical foundation for the review in place to kick off listening. That’s the fun part. You make time for listening.

LessLoss attacks environmental noise riding on power cables in a very special way. Though the Dynamic Filtering portion of the DFPC name suggests a filter, there is no filter as we know it in the cable, no capacitor or coil or similar. Louis Motek and his companion came upon the idea to invert the skin effect for slowing down rather than accelerating the signal portions affected by it. Slowed down sufficiently, they’d be effectively filtered out. The means to pull this off is a porous metal layer atop the main copper conductors which runs the unwanted HF content inside the porous metal maze where it literally gets lost.
