Do speaker cables really make a difference ?

Back in the days of yore everybody used lamp cord - and nobody complained!

Back in the day we used carrier horse & pigeons for transport and nobody complained.....

What happens to the sound(signals) when the signals  meet the cheap zip cord like internal speaker wires?

1 - the internal wiring of speakers is not as important, because (a) they are very, very short runs, way shorter than the speaker cables, and (b) they are inside the cabinets (not subjected to other environmental factors associates with the speaker wire going from the amp to the speakers).

2 - Good speakers use good internal wire, and not crap / zip cords.

Hopefully I did not waste my time writing this, as I smell a snarky question, like you folks always do. Oh well...

That has to be the most dumbass analogy that I have heard on confirmation bias. You folks don’t realize such known and true cognitive disorder works both ways. By definition, confirmation bias is the tendency we as humans have in seeking information and facts that confirm existing beliefs, rather than questioning them or seeking new ones.

Yes, people who believe speaker cables make a difference are not immune from confirmation bias. Let’s be real, all humans do. But, whatever they believe, is based on actual experience, and ownership of said cable. By definition, experience and experimentation ARE in a way objective facts. The “elephant” they actually “saw”. You on the other hand, base your opinion generally on stuff you read on the internet. The “elephant “ you never saw. So, who is the most “sick” from the cognitive dissonance ?

Another observation I have from “following” naysayers on audio forums: you spend so much time, energy, and effort in an attempt to “prove” what does NOT work. Debunk and disprove stuff. And almost none on what actually works. Why? Perhaps that way, by sharing YOUR experience on what works and how and why it works, you could become more useful to the Audio community? Actually contributing something 

I just want my cables to send through what is there not change it. This takes us back to simply proper gauge for length and amount of power you have.

And how do you know which cables do not change anything in the signal path?

Human nature is predisposed to a self-fulfilling prophecy...you believe therefore it is true. 

And you completely immune to to those shortcomings of the human nature? What you are describing is confirmation bias, which by definition, goes both ways.

@dadawada : would you be able to describe your audio system? I am very curious. FYI, there is a section in Audiogon called "Virtual Systems" where you can upload pictures of your system, describe your components, etc. 

If you cannot heat any difference in your speaker cables, any of them, your speakers suck. As well as your gear. I don’t really know how to put this mildly
