Please assure me I'm not going to burn my house down.

Todd WRT...

@williewonka I was using them with a dared mc 7p pre and a class D crown xls1500. 

Did you happen to observe any drop in operating  temperature of the crown xls1500 whilst using the Helix power cables?

My solid state source components ran noticeably cooler (i.e. by a few degrees) when connected with both Helix power cables and IC's.

e.g. My DAC dropped by at least 10 degrees Celsius - i.e. from quites warm to the touch down to room temperature.

Cheers

@jea48 I’ll join you in not recommending anyone use bundled cat 5 cables as PCs. I’m happy with with them, but am aware of their possible safety issues and have taken steps to mitigate them. Despite that, this isn’t a cord that can take the abuse a regular PC can.

@williewonka I can’t say my xls ran any cooler because it’s class D. It ran so cool, the fan hardly ever kicked on, even with the stock cord and it was never even remotely warm in any place I could touch. I saw a post in the tech talk section that made me think of you though. It was a PDF talking about power distortion in an industrial setting and how to mitigate it. One thing it mentioned was that, for industrial switch mode power supplies, having the neutral conductor at least 1.7 times the size of the hot conductor reduced the noise dramatically. Your helix design has the neutral conductor twice as big as the hot, as I’m sure you know..
Not sure if industrial switching power supplies behave like home audio, but interesting none the less.

Happy Listening!
