Speaker Cables? why all the hype for expensive speaker wire?

It’s voodoo audio that prays on the weaknesses of those who simply want to believe that something so expensive must be effective, yes? 

Yes cables can sound incredibly different. This is good to experiment with when you feel that you have tweaked your system to a level you can appreciate. Ah, believe it or not lamp chord sounds good with vintage McIntosh tube amp driving Altec Voice of the Theaters. Just know that for the most part $$$$ cables are not going to bring a $$ system to the next level. You can DIY some serious cables and save $$$ Youtube has some very good examples

“Yes cables can sound incredibly different.”   Prove it.

To who? Those of us who know have nothing to prove. The onus is not on us to teach, but on you to learn.

“Yes cables can sound incredibly different.” Prove it.

No one here owes you any proof. The documentation you seek is actually abundant, but you’ll have to work to find and digest it.

Here’s one especially thorough study. Very detailed. All variables controlled.

"This work shows that two system configurations differing only by the interconnect pathway are audibly discernable, even by average listeners with no special experience in music or audio ... electrical measurements conducted here indicate that noise levels may be one determining factor of sonic performance. The measurements also show that characteristics such as resistance and frequency response, that naïve consumers may focus on, are irrelevant for distinguishing HEA interconnect cables. "

Still, I think the best thing to do is listen and decide for yourself.
