14/4 wire for speakers- good idea? Bad idea?

I'm not a big believer in retarded-priced cables. I think many people dramatically overstate their influence and I think the point of diminishing returns on investment begins at about $100. Consequently, I make my own with decent wire and termination. The ones I'm using now are made from a bunch of 16g OFC I had laying around, paracord, heat shrink tubing, and some decent bananas. The wire got stuffed inside the gutted paracord. 6 wires got round braided into a cable. Silver solder attached the connectors. Black shrink tubing made it all look neat and tidy. 11.5g combined for each side of the cable moves plenty of current without the liability of big wire inductance. They sound good and look cool. 

why 14/4 would be a bad idea? Don’t they self-immune against external magnetic fields and produce low inductance, not too mention low resistance? Starquads are just fine. Many designers are using this geometry - Canare, Mogami, audioquest come to mind.

I think once twined at the ends it is effectively 11 guage. If higher end manufacturers use this design then it looks to be a sweet deal unless I’m missing something. I’m also doing bare wire termination. 

Yep, the higher end manufacturers does it this way and they are all wrong. Who in their right mind would even think of using such tiny cablage to feed a poweramp? Then why in h**l use such tiny strands on the low voltage secondary site?  

So to be clear cable in 4 or more seperate bundles twisted at the ends is not as effective or have the same properties as one braided strand? 

Thanks.
