Solid copper or stranded copper for speaker cables? What is your choice and why?

I had old copper speaker cable made by Audioquest (don't know the model).  The cable contains only two solid copper wires, one is thicker than the other. As I recalled, Audioquest claimed back then that thicker wire primarily carries lower frequency signal and the thinner wire is responsible for the rest.  I actually have not seen this type of design nowadays, BUT when listening and comparing it with the stranded wire (either 12 or 10 gauge) cable, I found the dynamic range is greater, and the bass is tighter and has more weight.  What do you think?


I have Morrow Audio speaker cables which are multiple strands and the ones I have are 1500 strands per cable. 


Having worked in a metrology lab for an aerospace bearing manufacturer, an R&D department for a major gas &oil company, and in gas & oil operations with electronic controls and monitors protecting millions of dollars worth of equipment, if it's good enough for that duty, it's good enough for my stereo.

Belden, Canare, or other high quality cable.

FWIW, in industrial applications we almost never use solid conductor wire.  They have a tendency to fatigue and break at junctions.  Especially if your wire strippers put a good nick in the wire when you are working with it.  Thermocouples being an exception, but those have been replaced by thermistors and RTDs, for the most part.

I found a version of this with 22 awg, these are 26 awg.


In any case, I ordered half black, half red, cut the connectors off, twisted the red/black pairs, added WBT type connectors, done.
