High Fidelity Cables, why most threads about them got deleted

They're alive and well. I have a few of their products, not the outrageously expensive ones. I've been receiving emails from customer service regarding a delivery date for a power conditioner module. Like many companies, they are experiencing production delays.

By definition, intellectual property is usually a closely guarded secret.

Having said that, most cable bells and whistles are not even worthy of a patent, because that would require some threshold levels of actual research by someone with a university education in engineering, and novel inventiveness and perhaps a couple other things, to be passed.

There is one company which does do a lot of genuine research, and it does describe the lengths it goes to deliver robust technology.  No secret that Blue Jeans Cables distributes the product (I trust mentioning that name is not a blockable offence).

I guess HFC have sneaked one of their guys in as a moderator.

Anyhow, like most sane people I'm sitting on my $23,000 thanks.

all I have to say that anyone that's crazy enough to pay $23,000 for a piece of wire is a sucker waiting to happen.
