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

@tzh21y  more important than what speaker cables you use are what speakers you use, how they are set up for best playback, and how the room is treated if, and where needed.  After those have been optimized, then worry about speaker cables IF you find the sound lacking.  If you love the sound, stay with whatever speaker cable you are using.  If you stop loving the sound, then change speaker cable, or maybe something else.  

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.
