Who has experience with audiophile circuit breakers?

The QSA breakers start at $700.00 And go to $10,000.00 depending on colour in 6 price increments. I installed a 20 amp Square D breaker, and a dedicated circuit to both of my stereo systems, with cardas audio plugs. There was a definite improvement, and less noise. That's as far as I am going with that. Unless I can see an exploded view of my $25.00 breaker and a $700.00 breaker I am not falling for an audiophile breaker. lol Bad enough I have Orange SR fuses in all of my gear.

And did the Synergistic Research Orange fuses provide a cost justifiable improvement?

If the circuit breaker is treated,  It will void the UL listing. The web site doesn’t describe the process. 

@ghdprentice  You know, I put them all in at the same time, so I can't tell you which one did what? All I know is I like the end result.

I'd hate to give my homeowners insurance company a hole to wriggle through in the event of some kind of mishap.
