Future of cables!

Wise observation Glupson...
I am a diplodocus I think....

I am an optimist diplodocus...
In few more years no more dac, no more separate visible speakers, no more visible amplifier....

I am also a pessimist diplodocus...
In few more years, no more humans perhaps or way, way less....

I am also a realist diplodocus....
The Beethovenian music for A.I. exist already it is an electronical one....

Kijanki , I did read your last post and according to your link what you said doesn’t make sense. Not to mention how energy OUTSIDE a cable can drive a speaker.

Energy is delivered to speaker by electromagnetic field outside of the cable.

From the wiki link.

No energy flows outside the cable, either, since there the magnetic fields of inner and outer conductors cancel to zero.

Has nothing to do with wires as we use them. It is all about computational speed and power. Maybe bandwidth. 

It’s a moot point whether the “signal” travels inside the wire or outside the wire. Since the sound quality is directly related to the type and purity of metal as well as the size of the conductor, all things being equal, we need not concern ourselves with Poynting vectors, as cool as they are. Furthermore, the speed of the signal in wire is given for copper not for the dielectric material and it is a high percentage of the speed of light. We DO however have to concern ourselves with the induced magnetic field, the dielectric material, RF and other related issues as we’ve seen in many other threads ever since Gandhi was a Cub Scout.
