Some manufacturers cables use unique arrangements of conductors and shielding.
I've read that simply twisting or braiding conductors together can reduce electrical noise/interference.

The effect some of these after market power cords can have on a system is that they reduce noise. I don't think a power cord effecting a systems sound is that crazy when you look at it this way, especially on digital components which seem to be very sensitive to mains quality, which is why we see linear power supply or battery supply upgrades to components with SMPS's.

But Matt, the subject was ATC speakers, not digital components!


I think you'll find my post was about aftermarket power cords and cable geometry, only mentioning digital components at the end.

Indeed, but I don't think geometry explains any perceived tonal changes, even if electrical noise is reduced.
How does reduced electrical noise - accepting that might be the case - change the sound from a pair of ATC active speakers? I trust ATC to design their amplifiers to minimise any such effects.

We're not talking tonal changes, just things like greater perceived detail, which, from what I can gather is brought by the reduced noise in the system.
For example, listening to some music where you might hear a bass tone, getting a quieter background in the system and listening again actually makes 2 tones or notes audible where they were merged into 1 previously.

Matt, the OP wanted something 'on the warm side'. That is a tonal change.

I guess what I'm saying is that a different mains cable cannot deliver that!

Yes, the mains cable won't change the tone to the warmer side, but it may reduce high frequency noise which can give the effect of being less bright.
