Blue Jeans Cable Sound Good???

coax is not used for balanced connections. Shield and ground are not the same. In balanced connections one rarely wants ground and shield connected. see https://en.wikipedia.org/wiki/Balanced_audio

the cable in the speaker comprises part of the load seen by the amplifier. If you change it, you may change the sound of the speaker.

Voice coil wire is very thin, perhaps 40ga or smaller. Using your logic, the 12ga is over kill.

Speaker wire reacts to the amplifier and with the loudspeaker. Just as one may change capacitors from electrolytic to mylar to polypropylene to PTFE to PIO and detect no, some or great change, so to will changing speaker cables affect no, some or great change depending on the amplifier and loudspeaker. Similarly for TT/CD/DAC->Pre and Pre->Power connections.

The messy bit is that cables must be judged in a system and there is no guaranteed magic bullet.

In my speaker the entire system sits in the top like a can, from the binding posts at the bottom to those cans is basic 12 guage wire , there is also a 4 prong metal connector between . I fail to see how anything more than a basic 12 guage speaker wire which the manufacturer recommends is going to matter unless I  rewire  from the cans to the posts.

There are many ways to arrive @ 12ga, any of which may sound different or not depending on amplifier and loudspeaker.

read http://ielogical.com/Audio/CableSnakeOil.php paying attention to how various cable geometries interact with the same amp and loudspeaker topology.

ieales, I have a question a bit off subject. I installed cat6a shielded thru out my home. I bought a shielded patch panel and when connecting the  cat6a the shield of the cable is fastened to the panel. A ground cable is connected to the panel which drains off any interference in the shield.  Why is that not the same for audio?  I just asking because I'm a bit confused? I realize shielding stops interference, should that be drained of into ground.  I am a newb just trying to understand.  Ty

CAT cables are balanced end to end. The patch panel is grounded, but the cable shield is not connected at the source / destination equipment end.

When the screen is connected at one end only in twin or star-quad, it functions as an electrostatic shield and does not carry any signal current. A typical RCA coax carries current in the shield - not a good idea.

Lots of audio gear is badly grounded. Manufacturers add 3 prong power to unbalanced equipment 0v and presto, ground loop.
