What do you mean by 1d and 2d? If it's dimensions a diffuser must be 3d or it isn't a diffuser.

Once you get to about 50 cents a foot for the wire and 5 dollars each for the connectors there is nothing 'better'. So for a ten foot cable, for instance, don't spend more than $20, tops. If you do...

Yes, at that distance Allison Effect will be moot. Where Allison Effect is problematic is with mains and subs, as the reflected waves come off the front and rear walls, and you're sitting in an...

BS is a substance. :D

Point of fact, an electron wave in an insulated wire does have a lower speed than in an uninsulated wire. On average it's about 0.7 times the speed of light. Different...

Use it until it's actually obsolete, say ten years down the road. You no more need Atmos now than you do a 3D TV, which I'll also get when the majority of movies are 3D, along with broadcast TV.

You were already given a serious answer. Quantum mechanics have nothing whatsoever to do with how cables function. Any source that claims so is either lying or clueless, or both.
