The Belden 83803 is a 12 gauge, two conductor tinned-stranded copper with ground. It's claim to fame is the copper braid which serves as a shield.
The specifications certainly are impressive, but since I have not tested it, I don't know if it outperforms traditional 12 gauge solid copper Romex. Or if the copper braided shield is the magic ( if any ).
The key here at least in your case, seems to be the shield. Another option is plugging the offending items into something like Magnum Line suppressors by Electronic Specialists of Mass.
I have my microwave, refrigerator, air conditioning system, computers and alarm system all plugged into Magnum suppressors. The suppressors make audio equipment sound bad when used to isolate the stereo, but used on the offending gear, it is not audible, except that it cures the problems.
Good news is when you move, all the isolators move with you to apply to the next group of appliances that are "bugging" your stereo.
Last, traditional 12 gauge Romex is improved by making a separate ground for the stereo runs. When you lift the ground (within the Romex) turn the ground back and clip it off at the wall receptacle end. Leave the other end attached to the neutral bar in the service (breaker) panel.
This serves as a partial shield at no charge. Another shied is traditional conduit. This would be the metal type and not the PVC.
Installing conduit and traditional Romex may cost less than the expensive shielded Belden, and in some cities improve your fire rating, qualifying you for lower insurance rates.
If these efforts do not lower the noise floor sufficiently, a package of Quiet Lines will make everything sound better and again, are portable.
