Now I happen to think 14 and 12 gauge conductors would be better for speaker cables than 18 gauge. Even if you combine two 18 gauge conductors I feel the single 12 gauge conductor would be better....within the same brand. This is based on my listening tests with several well touted brands of conductors. No matter the outer insulation the heavier gauge within each brand always sounded better with speaker cables. Improved fullness, bass drive, dynamics and midrange bloom. I would go with the 12 gauge 🤓 for moderate to high power amps with less efficient or moderately efficient speakers. Highly efficient speakers coupled with a low watt tube amp work fine with 16 or 14 gauge provided the length is under say 10 feet.
Will the 12 or 14 gauge Neotech wire sound better than two 18 gauge VH Audio conductors in your speaker cables? Really don’t know until you try. While the Neotech gauge is more to my liking will that positive outweigh the positive sonic qualities of the VH wire? Don’t know as I have not compared. I would not use less than two VH Audio 18 gauge conductors in your speaker cables however.
Question for you. Neotech sells the solid core copper wire in PVC for $2 per foot less than Teflon. Since it is the same internal wire and you are stripping off the insulation, it would seem smart to buy the PVC version of the Neotech wire. Perhaps you shared this, but I may have missed this.
Thank you so much for this power cord discovery!
