Speaker cable solid and strand copper cable

NO! All electric signals travel through a wire at the same speed - 186,000 mps. Solid core or stranded doesn't matter. 

I’m getting bette definedr treble with Audio Arts silver plated stranded than Tara Labs solid copper.

I think you would be better off looking elsewhere than cables for this. Also, solid copper tends to be rather fragile. 

Give us more details about your system and room. Keep in mind as well that not enough treble is also a sign for too much bass. What I mean is that the balance is important. 

@audiosens - solid wires are better for all signal transfers.

Grnated - solid wires can fracture, but I don't move my cables that often

What may be causing your issues is

• the insulation on the wire
• the geometry of the cable.
• type of wire used - the best copper wire today is UP-OCC copper
  • or you could opt for solid Silver UP-OCC wire

Take a look at my post on this iink

However if oyu apparent lack of top end is due to the speaker - there is no cable that can rectify that

If you have any questions just ask

Hope that helps - Steve

All electric signals travel through a wire at the same speed

Electricity does not travel through the wire from what I have been taught. It travels on the surface of the wire. Bigger gauge wire has more current carrying capability due to greater surface area. 186,000 miles/sec.

dc will travel through the core of the wire.

AC will move to the surface, depending on the delta involved in the given moment.

the molecular-interrelationship within the lattice of the given alloy or element, determines the ’resistance’ as we call it.

this then relates to the splitting into the two fields and their different ’orientations’ or values in the given calculation and observation. The ultimate end of the line logic domino... in that line of thought ....is that within superconductivity itself, time does not exist.

The calculations and formulas and ’laws’ are derived from observation and repeatability of observation. Observation is therefore, logically, ’king’ in science and cannot and will not ever be superseded by ’laws’ that don’t really exist. (this is where laypersons get confused and it can also be confusion in engineers, who were not taught this point, overall)

They are not really laws they are just theories with high level of repeatability and expectations in repeatability. We call them laws for the sake of convenience to not confuse people who think linearly and not laterally. Hint, the vast majority of people think linearly. They are wrong about science law, horrendously so, but we have to let that go, as they get violent when confronted about it - not logical.

All that be as it may, the rate of propagation, in an alloy or element bulk lattice, is tied to the interaction of the material’s electrons under motive differential.

But wait..there’s more..much much more....

I was gonna say that..  In my dreams. :-)

Thanks that was a great piece of information, that I understood.. 

You must be a REAL teacher. It's rare that people explain and keep my interest. Wonderful!

Pure silver is the best. But for only 6 feet I doubt you will hear a difference 

fiesta75, thank you, I am trying to compensate one of my ear loss,  I think I will have to live with that ;)

fiesta75, Now, I can hear the singer breathing, but before, it was as if inside the loudspeaker the fluidity of the music was fighting, because of the bad connection of the loudspeaker and jumper wires. Now it's so much more alive, my moderately deaf ear is able to appreciate the music, there are so many details that stand out now. It really is another musical world.

Glad you’re happy. Pure silver is the best conductor but $$$

Solid core copper cables sound better to my ears than stranded copper cable.  This preference extends across multiple brands.
