@MickeyBoy Greetings
I have read (but don't ask me to quote the source which was probably in the 1960s) that properly crimped connections are better than soldered.
They are supposed to be airtite. They are used in aviation and medical applications where if it was more reliable they would solder things.
Of course in the aforementioned applications there would probably be a bunch of procedure validation tests.
I have worked on lots of equipment with high current connections. If they weren't good connections they would have scorched. ( I once had a massive series of failures on 1/4 " Stakon connections. The high resistance was between the male and female Stakons. It took 25 years and was a damp environment. Actually an humidity controlled damp environmental chamber that ran 24/7. I cleaned the mess up by eliminating the stakons altogether with crimped butt splices)
I think, like cabling generally, it would be hard to discern an audible difference.
