Has anybody tried using single solid core cables?


At a recent hi-fi show an exhibitor auditioning $47K speakers repeatedly asserted the following: "Any solid core wire, even $0.03 a foot is better than any multi-strand available. Experiment for yourselves, you will be amazed."

My question before I ditch my multi-stranded Audioquest Indigo cables in favor of 4 individual single solid core 18 gauge cobber cables from Home Depot for my newly acquired SA Mantra 50s, has anyone tried using single solid core wires?

I'm not sure why cables have to be thick since speaker source impedance for back EMF is mostly resistive but it will lower inductance of straight wire. Skin effect starts at gauge 18 in copper at 20kHz. Stranding wires will make it worse because current will flow toward outside jumping from strand to strand thru impurities while skin effect still exists. Better solution is to use insulated strands. Placing them in regular fashion puts them in magnetic field of each other still allowing some skin effect. Better solution is to place them either on hollow tube (like in Indigo) or as a tape so that each strand is only in magnetic field of neighboring strands. I don't know what is audible and what is not but Indigo was great improvement over thick stranded Monster Cable (that was plain horrible). Later I found Indigo to be thin sounding and replaced it with Acoustic Zen Satori Shotgun that I will likely keep forever. It is total of gauge 6 and I have no idea why.
Al, perhaps you're right (as usual) because if there is any chance of smearing sound because of small cable resistance vs frequency change (caused by skin effect) when wire is too thick, then it has to apply to changing (vs. frequency) impedance of the speaker loading, when wire is too thin.

Perhaps solid gauge 14 can be a compromise (AQ type 4 etc) without paying too much.

Happy New Year!
