An industry guy came by this weekend and they did a shootout with some crazy expensive power cords (something like $8000-10,000) they both agreed that our B24 was better.
The problem with the demo that was run was that the power cable you're referring was that it was not a properly controlled experiment. The cable you're referring to had just been transported in a motor vehicle from Utah and did not have sufficient time to settle. Vibration from transporting a power cable in a vehicle induces triboelectric noise into the dieletric, which impacts the cable performance and the impact of this is quite audible. Further, one cannot determine which PC is better simply doing a quick "A/B" swap. In order to do a proper comparison between power cords there needs to allow sufficient time for the power cord to fully settle fully, which takes 48-72 hours.
If one is going to do an A/B comparison, the demo needs to be set up in a scientifically controlled manner with two identical systems so that one can compare the use of the two different power cords as the only difference between the two system, without, and this is the key point, one power cable having to be swapped out for the other. Otherwise, if one power cord is swapped out for the other, more vibration is being put into the power cord being installed, and it will again require time to fully settle.
