It is perfectly normal for the voltage to sag somewhat for an instant when turning on a power amplifier, as it's filter capacitors charge up. I would have a professional electrician evaluate your wiring to see if there is indeed a problem. A circuit breaker is nothing more than a fuse - it will not effect voltage sags one bit one way or the other. All it does is trip when a pre-determined current flows, presumably to ward off fires. There are electrical codes that have to be followed too, so he would be the best one to give you an answer. The only real limitation is your house wiring gauge. If your house is very old it may be too small. Again seek professional help with such things. House wiring is not something you "experiment" with.
