Do speaker cables really make a difference ?

I keep seeing comments about the different sound you get from different cables. I don't want cables with a "sound signature" 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.

I had a very high resolution system, and added flat copper speaker wires to the system. The change and improvement in sound was very audible. The cables were wide, and flat. That drastically increases surface area, while maintaining cross sectional area. The improvement in sound was most noticeable when listening to vibes.

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

@randym860 EVERYTHING has a sound signature. It's not alway the tone, or the frequency curve, it can be "precision", "depth", "width", "prat". Nothing is absolutely neutral and that includes cables. Some are closer to neutrality, for sure, but absolute neutrality doesn't exist.

@dentdog of course. That "expectation bias" explanation is utter BS. I have drawers full of audio cables, sometimes I swap them around, just for the sake of it, I already own them and have no "expectations" for "better" sound, but it sounds different every time. Same goes for power cord, I was rearranging my system lately and thought I would swap the various power cords around again and try them on different components but only ONE arrangement (this power cord on THAT device, and so on) gives me magic. The rest sounds vastly inferior. I already own the power cords, only the different requirements of the various electronics in my system decide which power cord goes where, not novelty or price or "pride of ownership". That argument is for deaf "audiophiles" with a lousy system.
