No one actually knows how to lculate what speaker cable they need

@b4icu.  
I voice my cables by ear.  I use what some refer to as “tone” wire and change the gauge, construction and connectors based on what folks want sonically.  I am a custom builder.  I love the sound of Duelund stranded and tinned copper in oil impregnated cotton and use it often. 

I also perform modifications to speaker crossovers and tube gear.  I know what parts sound like based on my long experiece using them and match this knowledge with what the customer is looking for. Yes, I use my ears and known sonic differences between types and brands of wire, caps, resistors, inductors, rectifiers etc....

It is just me making cables out of a spare bedroom driven by a passion to help fellow Aphiles enjoy their systems more fully for reasonable money. Very small part time business that is gratifying.

Thanks.

I assume this method of "voice cables by ear" would apply when you sale a complete system, to include the amp and the speakers.

What if a customer comes in just for a speaker cable, and has a gear that you are not so familiar with its sound?

If I may summarize your method, it is mostly based on your intuition and some past experience that is based on your personal likes and dislikes. I have a little problem with that. You may know by now, that two people can listen to a system playing in an environment, and have different say about the very same sound. Wouldn’t you feel better if you would have a blue print or a formula in hand, that would specify by engineering methods what is the optimum cable that customer really needs?

What is the thickest cable you can offer a customer? How much that cable cost?

When you find one then by all means clue us in.  If everyone had the same opinion of how the “optimum” cable sounds then we would only need one cable manufacturer.

No, based on my customers likes and dislikes and areas they want to improve on. They know how their rig sounds and what they want more or less of etc...Many thrilled customers as my feedback testifies to.

I sell lots of ICs and USB cables right now.

There is no blueprint that can handle human preferences and the countless system iterations and room environments that exist. It always comes down to the ears of the customer are our own ears. Always.

Sorry you missed some of this tread, explaining that every amp-speaker has its optimum cable, by engineering calculation. The tweaks of a sound system shall be done other than on a copper wire between the amp and the speakers. No, no one cable for all. The cables are different by the equipment they serve and length required.

Not to say, that the claim is of having a speaker cable that would bring out 100% of a system, rather than have a wire you or others might suggest, that you think is good sounding, but would deliver only 20%-50% of that system's potential.

Please be kind to read the sharing on this thread, of people who made the change and were kind to share. None of the cable you are talking about would get this kind of improvement.
