Here is some fodder for you EE's and other Flat Earthers. From an ad in Audio Advisor. 6ft $561.
"Cables by Analysis Plus. Unique Hollow Oval Geometry. Analysis Plus product engineer Mark Markel determined that round cable used in conventional speaker cable designs exhibits current bunching, skin effects, and other frequency characteristics that degrade signal quality. After many computer simulations, he found that a hollow oval cable was the best design. It maintains a low resistance value, even at 20kHz, where the resistance of the round cable has increased dramatically. Etc etc." May I take your orders?
This statement is gobbledy gook. It displays both ignorance and cynicism.
Ignorance – they don't seem to understand the differences among resistance, inductance and capacitance in cables carrying AC signals. Inductance and capacitance vary with the frequency, but resistance is the same at any frequency. That ignorance alone is enough to make me not believe anything else they say.
Cynicism – they believe potential buyers would fall for such misinformed technobabble. As you seem to do.
They claim to fix "characteristics that degrade signal quality" without ever demonstrating that the degraded signal quality actually exists in round cable, and without demonstrating that fixing it, if it exists at all, can have an audible effect. They avoid claiming an audible effect because they have no evidence for it. They clearly know that such a claim – without evidence – might be called false advertising by the Federal Trade Commission.
By the way, the term Flat Earthers was one I just heard used by a cable salesman to refer to non-believers when I was asking questions.
You heard that from a cable salesman? Ask that salesman what the mark-up is on the cables he's trying to sell you. I'd bet it's much higher than the mark-up for any electronic gear or speaker he might be selling.
In the argument about whether cables make a difference in audio, there are objectivists and subjectivists. The objectivists require evidence before they believe a claim. The subjectivists believe faith is enough. A Flat Earther, in the past, rejected faith and believed the emerging evidence for a spherical planet. Today a Flat Earther is someone who rejects abundant evidence for a spherical planet.
Calling someone a Flat Earther, when they require evidence instead of faith, is getting it backwards. It comes across as a direct insult. I think you're well aware of that.
