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

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. 

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. 

Excellent insight guys. 
My gear is not super high end...but certainly not cheap, so I most certainly want to benefit from the dollars spent to date....let alone have a configuration that may create havoc between speakers and amp. 

Point of note Im currently running a Bryston 3B3 into Volent VL3 Speakers. My preamps (phono and preamp are all tube...Zesto and Lamm ll2.1 respectively). I started upgrading interconnects with a mix of Morrow and Transparent cables (all about 200 bucks used). 

Sounds like its time I did something with a better design for speaker cables now. 

More suggestions in the $200+ used range?
