I’m right with you on a number of topics, but......what does this post have to do with audio? Seems more like a life’s choices post.
I have actually used some very thick (10 ga) solid copper wire from my preamp to power amp. Worked great! System sounds the same as with my 12 ga stranded copper wire.
Older audio electronics used copper wire in power supplies without problems.
I didn’t keep it in as it is impractical - zero flexibility, hard to fasten to terminals, and not significantly cheaper than stranded.
And I’m glad we agree on this subject. You are obviously an audiophile who knows what he’s doing. Have the knowledge, and know how to apply it correctly.
It’s just something that’s been bugging me over the years. Folks who are amazed by high end audio systems, yet who can’t get themselves to spend the coin on them.
I wrote about numerous reasons for this in another post - the truth is that many non-audiophiles don’t want to invest the time, money, effort, or dedication. Other hobbies can provide instant gratification; and audiophile hobby isn't like that.
Now I’m not saying this is true for every non-audiophile out there. But of the 100 or so people I’ve asked, their reasoning has aligned with what I said.
What really bugged me was them getting me excited, asking me technical questions, and ultimately giving me the impression that they were going to be building a system. It was wasted time.
