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?

Quite the mixed bag of opinions in this thread - so here’s my observations of wires tried in the past year :-)

In order of preference (Good to Best) by cable type

Interconnects (signal wire)...
- 1 x16 and 2 x 16 gauge Duelund stranded - Tinned Copper in Cotton/Oil
- 2 x 18 gauge Solid copper with AirLok insulation - VH Audio
- 2 x 18 gauge Mundorf Solid (bare wire) - Silver/Gold(1%) in Cotton Sleeve
NOTE: - the last two appear to be extremely close sonically

Speaker (signal wire)
- 1 x 12 gauge Duelund Stranded - Tinned Copper - polymer insulation
- 1 x 16 gauge Duelund Stranded - Tinned Copper - Cotton oil
- 2 x 18 gauge Solid copper with AirLok insulation - VH Audio

Power Cables (Live wire)
- 1 x 12 gauge Duelund Stranded - Tinned Copper - polymer insulation (FOR SOURCE AND AMP)
- 4 x 18 gauge Solid copper with AirLok insulation - VH Audio (FOR SOURCE AND AMP)
- 1 x 18 gauge Mundorf Solid - Silver/Gold(1%) in Cotton Sleeve (FOR SOURCE COMPONENTS)
- 1 x 12 gauge Neotec OCC Solid copper (bare wire) in cotton sleeve (FOR AMP)
OR if oyu don’t like cotton sleeve for power cables...
- 1 x 12 gauge Neotec OCC Solid copper (bare wire) in teflon tube

Please NOTE: the neutral wires on all of the above cables are stranded, Silver Plated Mil-Spec (Cryo treated) with Teflon insulation - I have tried better quality wires for the neutral, but they made no difference.

Are there better wires? - probably, but these are the wires I have settled on - for now :-)

In general, I observed improvements in...
- Clarity - more noticeable vocal textures (e.g. sibilance) and cymbal work
- Details - in both upper frequencies - a lot more venue acoustic details and for lower frequencies - bass textures
- Dynamics - significantly better bass "slam" and crisper drums/guitars
- Image size and artist placement accuracy and focus in width and depth

It appears, to my ears at least, that Solid conductors provide the best sound quality - however, the type of insulation also plays a significant role in sound quality...
- the best being a bare wire in a cotton sleeve OR in a Teflon tube that allows for air between the wire and the side of the tube.
- Insulations that are molded onto the wire, like Teflon, PVC, appear to have a significant impact whereas foamed insulation variants (like that on the VH Audio wire) performs noticeably better than non-foamed.

Just another opinion :-)

@runnin , The impact of the inductance of ROMEX will far exceed any impact of skin resistance at audio frequencies, i.e. 20KHz.

On using romex or "HomeDepot" wire, there is a drawback. Larger gauge copper has skin effect, and the wire will also oxidize quickly compared to OFC.

I agree with williewonka's findings. VH Audio's wire with Airlok foamed dielectric is an excellent choice. The V-Quad cable for use as DC umbilical cables get two thumbs-up from me.
