Do speaker cables really make a difference ?

How about one's perception involving speaker cables you may enjoy thoroughly on a trial loan but they're the most expensive? I mean, I don't want to like them better but it's pretty undeniable as to the benefit. I want to like lamp cord better. 

My overriding measure of listening pleasure is lack of listening fatigueWas rocking it for close to six hours last night. Purist aqueous. Hate to pay but may have been reeled in. Fourth set tried, one more to go.

@rsa speaker cables improvement' leading to lowering loop resistance and inductance, does make sound impact. the longer cable is the more impact you will hear. 4 Ohms speakers also will show higher impact vs 8 Ohms set. 

I hate to sound Prickish, But i have learned that the better the audio gear, the more noticeable changes are to the ears. Once i stepped up to more higher end gear as in components, the cables made more of a difference to me. Stepping up in components were very noticeable, then adding different cables. I tested 2 sets of speaker cables on my basement system, The dealer brought them over to listen as well. One set was very close to what i had, $600.00 the next pair for $1300.00 sounded like someone covered the speakers with blankets. The dealers face turned red.

Find a dealer that will let you take the cables home, all the reviews in the world can't prepare you for what they will sound like in your home.

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.
