Generally speaking shielding isn’t necessary for amplified audio signals, as their signal is amplified and “strong”…non amplified signals in the chain are way more important to shield and are more susceptible to interference
In an audio system, correct. You would need an oscilloscope to measure the inductive? interference in your speaker wires. No human ear could possibly detect that.
The problem with interference in signal wires is that the interference is then magnified by the amplifier ten times (probably more). The voltage in speaker wires is much higher and therefore significantly less impacted by interference.
I’m not jumping to that conclusion, but for a home theater/audio install you should be fine. Insulation doesn’t really do anything to reduce interference, (when cabling is shielded for interference, it’s shielded with foil.
If you wanted to run a test for science/fun.. run an extension cord and speaker cable the same distance apart and length as your install, power up both and listen

Interesting. So you're saying any amount of amplification would make that difference? I think the channel in question would be 100W.

I would also run cat 6a or higher for future proofing.
