And besides, "professionals" do not use 6.3mm jacks for the speaker
connectors, unless the contacts are gold plated. With nickel plated
steel, contact resistance is unstable within a few milliohms which is
no-no for any decent audiophil!


** You must be thinking of "audiophools" not audiophiles.

Nickel plated *brass* 1/4 inch jacks and plugs are fine for speakers,
millions of instrument amps have used them for decades. Removal and
insertion plus occasional cleaning is all that is needed.

Gold plating is only for small signals.

Ah, was kidding...
For the instrument amps, perhaps a jack is OK, but audiophools shall use
enormous gold plated terminals, and a special litz speaker wire of perhaps
2000 insulated 0.07mm strands each, so that ohmic loss is small and constant
from DC to 1MHz..Otherwise you lose transparency of the highs!


I saw one site selling multi-thousand dollar speaker cables with the
'feature' that in THEIRS the signal traveled at 90% the speed of
light. Which, of course, is critical when sending audio 10 feet.
