Hmmm...

I sense a marketing opportunity. Which isotope conducts electricity
better?
Couldn't we get megabucks for isotopically-pure, oxygen-free,
000-gauge,
gold-terminated speaker cables?

lololol

Dang! You mean it's not already being done?

Just winging it here -

It seems to me that the larger nucleus would have a weaker grip on the
conduction electrons. Therefore the Cu65 wires would be preferred.

Now I can imagine a competing company with a good theoretical reason why
the
Cu63 wires would conduct better. We of course would have to conduct some
blind ABX listening tests to determine the real winner...

I actually did an internet search for it, because I know what hi-fi people
are like, and was stunned that it wasn't being done. Anyone willing to rip
off their nice flow-soldered circurt boards just to replace the solder has
to be a market for this.

Just tell them it's better and why, how much it costs, and we'll make
ourselves a fortune.
