OP shielding can really mess up the sound if your not careful.
I have a less is best type system.
PC, RCAs, XLRs and speaker IC, can ALL reduce RFI EFI with a weave, so it doesn't throw a blanket on the SQ..
The quality of the material and different conductors, whole different ball game. The Composition!
You keep using the word "Geometry", size and shape, relative position of figures, and the properties of space...
Composition, the "what" of the WHOLE, (what it's made of).
Still, BAD cables, need to be good cables, crazy thing to say, but cables only go so far.. like 2-3% if they are good to begin with. NEVER jaw dropping.. LOL, that one kills me..
No cost/ low cost solutions, get my attention...and have improved my system more than ANY cable.. BUT, I started 40 years ago, with large conductor, pure silver and pure copper, USAF surplus.
The improvements over the years have been VERY minim, because of that alone...Like ZERO, other than network (HARP Box) an added wire or type of wire, armor....maybe some of the tuning terminal ends. Not much of that either.. I've had 3-25,000 cable over here. ALL were red faced. One cable made MY 300s shake rattle and roll..Oscillation big time...MITs
I was at a house with JBL Everest speakers, everything was wonderful.
Speaker IC was off the real, as per installer...10 gauge copper, in the wall, with short tuning patch cords, from the wall to the speaker..
GREAT speakers.....good cable... SQ... oh yea....
