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


It goes back to cable manufaturars, mostly provide no relevant data! to sales and the users. None will answer this!
Whay do you think that you own now the optimal cable to your setup?
I think I've figured it out.

b4icu,

"...you really think that giving away this formula is a brilliant idea, to satisfy your personal need to know?"
I do not think it is a brilliant idea but I also see no harm, unless a person is starting a business with that formula. Of course, there is no desperate need to disclose it either way, the world will go on. I am not arguing about validity of questioning and establishing the formula, but the topic and intention of the original post is less than clear. It got even less clear over the ensuing posts.

Those people who do buy stories and expensive cables may be happy, too. The value of those cables perceived by you and me may be different than value of those cables perceived by them. It works for them, if for nothing else then because the cable came with a story. Many products are marketed like that and buyers are not only happy but proud, too.

The tone of your posts suggests that you dislike expensive cable manufacturers approach and stories they attach to their products. You imply you, to say it simplified, have a formula that is far superior to their stories. As a neutral observer, I would say that putting your facts/formula out would go much further in debunking the myths than just saying "they are bad and I figured it all out". It would simply give more credibility to your statements.

I have no personal need to know the formula or any theory behind wires, but I do hope that han_n does find your calculations useful. It would definitely be much-needed first step in some meaningful direction.

By the way, out of sheer curiosity, how did you guess that I am "Mr" and not "Mrs"?

b4icu:

If you have such a "formula," which implies a quantitative, calculated solution based on quantifiable input factors and the means, instrumentation or otherwise to verifiably measure such quantitative variables, what are the factors that are measured and used to calculate the optimal speaker cable features?

I’ll bet you have absolutely NO such measurable factors and no such instrumentation and are simply blowing smoke up all of our proverbial exit chimneys.

Quantifiable, calculations, formulas, measurable? Yeah, uh huh, right.
Yes, it goes like:

amplifier + speaker = cable, which in turn means:

speaker = cable - amplifier
or
amplifier = cable - speaker

obviously, neither speaker nor amplifier can be a negative quantity, which means that cable > speaker and cable > amplifier.
