FWIW, the first officer I was flying with yesterday spent most of his career as an avionic (flying came later to him).
We were having this discussion with a fellow flight attendant who happens to be an audio buff and is the type to spend hundreds on interconnects, power cables/conditioner and speaker cables.
The F/O-avionic explained to us that any intact wire of the proper gauge will do the job and unless you get to see the wire being used before listening, you won't objectively hear the difference between clothes hanger wire and $1000/ft cable...
But what was the experience shared?
Did the F/O solder some coat hangers together and compared them to $1000/ft cable?
I love homespun homilies. And they are good food for thought, but I don't always believe something just because someones tells me so.
I would agree for a lot of systems, goals, and budgets it may not make any sense.
You kind of have to weigh evidence and keep an open mind sometimes. Like on a forum, the "discussion" is sometimes about posturing and showmanship rather than a facility for determining truth.
Nothing like experience to really learn and sort what life is about.
I never tried a coat hanger. But I have tried various speaker wire from Monster to Audioquest and I was able to hear a difference sometimes and to varying degrees. And nowhere near $1000 a foot. I got 80 feet of Audioquest Type 4 Blue solid core $2.50/ft. for $216.40 including tax, new at Magnolia HiFi back in 1995.
Certainly not $1000 a foot.
Now most of my media sounded great before I got the Audioquest, but I was on an anal quest to tweak out more detail from my Manhattan Transfer tonin' CD track 1 Let's Hang On, listening to the ratcheting sound, and tame the harshness or brightness from my High Society soundtrack track 4 Who Wants to Be a Millionaire with Celeste Holm and Frank Sinatra. Wire was the cheapest upgrade at the time.
This was before I got into vintage in 2008. Today, I wouldn't bother with expensive cable and wire other than what I have accumulated. Priorities change. And a lot of vintage speakers and components won't accomodate the solid core wire let alone a coat hanger. Today, it's easier to swap out components with vintage because they are now so much cheaper than when new. If I were to buy new components back then it wouldn't have made any sense - they would have been more than the $200 I invested in wire. I wasn't out to prove anything to anybody but myself even then.
