I go out of my way to run all my wires along fluorescent tubes on dimmers on poorly grounded circuits.
To me, the increased harmonic distortions are reminiscent of a 1950s-era tube amp and impart a classic rock and roll sound into everything I listen to,making everything more musical.
Does that actually work to make things sound more musical? I haven't seen it on those elitist A/V websites yet. I might have to stop at Home Depot after work and get some fluorescent tubes and set something up.
Again, my post is just what the "experts" train as best practices. There are many things that aren't "best practices" about my setup, but if the effort is little or no additional cost or time to reduce most of the proximity, then why not?
But back to the fluorescent tubes. Do they have to be run inside the walls, or can I mount them in the room? Can I use blacklight tubes? What about simulated sunlight tubes so that I can get a tan while listening to music?
