Double up on speaker cables

Cables don't make any sound they can only hinder frequencies so when you put them together you will only get the negative effects from both cables. It's not that one cable is airy it's that that cable has poor response everywhere else. Your speakers need to see a window of impedance and doubling the cables will change the impedance so there are at least 2 insurmountable problems in your experiment. 

The best cable is no cable at all, this is why powered speakers with line level crossovers are the future.

It's definitely better to post about the idea, rather than.... you know.....trying it.

I say use the ones that are "detailed and airy" on the positive side and the ones that "carry more mid bass" on the negative side. 

I continue to be astounded that intelligent, educated adults still believe a few strands of silver can provide "airiness", " finer detail", "improved mid bass" and bring out "nuances" only previously heard by golden eared fruit flies. Even more ridiculous that these strands of silver can be packaged in hundreds of different  options, all providing different sound signatures. Is there some magical, proprietary unicorn dust sprinkled upon them? The fact is, a cable transmits a signal from source to end point. Nothing more, nothing less. The only difference in sound you will hear is the difference in sound you want to hear. Pure placebo. 

@timkeough1964 Well, good for you. Keep being astounded.
