Best Circuit Breaker for a Dedicated Audio Line

I'm putting in a dedicated electrical line for my audio system.  It uses 8 gauge wire and 20 amp hospital-grade recepticals.

I have a Crouse-Hinds breaker panel that accepts MP, MP-A, MP-T, MH, MM, MH/MM, MHGC, MD, and MD-A breakers.

So, from an audio stand-point, who (make/model) makes the "best" 20-amp breaker that will fit the panel?  Within reason, cost is not an object.

I just had my second direct line put in for my amp… I used 10 gauge. I was happily surprised how much better it made my system sound. I already had a direct line… this just separated the amp and other components.
