Does raising speaker cables off the floor really make a big difference?

I have no clue as to why folks think "raising wire off the floor" is a "cash cow tweak". There are numerous ways to do this and spend a pittance of money. Cups, CD cases, etc. Seems to me these individuals have little interest in experimenting with their systems to improve the overall sound. One must ask why they are commenting on something when they have no practical experience to back up their claim.

Yeah I have no interest in experimenting with tweaks I'd rather listen to and buy music. I wonder if I put magical risers under my drum kit would change the sound? Maybe a sack of magical rocks on the kit will make them sound better? Or maybe a better drum kit would do the trick.

Whoa! What? Hey, listen, junkhead, those magic rocks as you call them put me on the map. Why it was the map of East Timor no one knows.

I wonder if I put magical risers under my drum kit would change the sound?

Not even in the same ball park. If that is what passes for snark, then I despair for my fellow man. Keep up the drumming though......

All the best,

Maybe your just not a very good drummer...☺
Why are you bashing an idea you refuse to try?
Especially since you can test it out for little or no cost.....
