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.
