$30K for 3 meters speaker!

Open up your speakers and take a peak at the wiring inside them.

Purchase identical wire and use that for the cables from speaker to amp(s).

"If it's good enough for the inside, it's good enough for the outside"!

That's a quote from the late Sam Tellig of Stereophile.

@rx8man Haha, Sam was joking when he wrote that, but it is very interesting yours really do match. Pretty sure most don't.
