Who makes budget speaker cables which are truly “good” or “exceptional” in quality?

Who makes budget fantastic speaker cables?
Me!
And I'm serious about this. I happen to be working at the right place (a theatre) to have access to the best possible wires. So I take a few meters from the Sound department at no cost and just plug them in my system.
I can assure you that nobody notices the difference between these improvised cables and my expensive Cardas, Wireworld or Morrow. I've done the testing many times and I'm selling the other cables to retrieve some money. DIY with the best materials is the right choice.

All designers of cables were originally DIY. No exceptions.

If you don't hear the difference, save your money.

However, sooner or later, most audio people will hear a difference, and marvel at it.

The trick is to apply the right form of reason to what is heard. That is a multifaceted task of enormous complexity that can take decades to unravel.

No shiny red button quick fixes where ignorance can throw money at it and make it better. That's where the ignorance and bull combines to make a mess out of things. Just like it does in all areas of business.

You got that right bondman ...
