What measurable signal alterations or audible changes would result from changing the metal of the binding posts?
I don’t know, it seems a bit magical… but it has to do with magnetic flux or whatever it is called as the current generate magnetic fields.
And a few of people I respect a lot, and many that I do not respect as much, claim it is important.
Whether it makes a difference of not, Danny was spruiking them as something to fix, and the Sointuva already has them.
It also better 2 better drivers, than the SF speakers… and it has 2 passive radiators versus the port of the SF.
So looking at a $2500 speaker with $500 upgrade (plus time), still does not seem to be an improvement unless one wants a tower and lower frequency extension.
And the Sointuva have shockingly good bass, down to ~40Hz.
Or one wants a painted black speaker, or an 100 other non musical factors.
