Power conditioner and high end power cord

A 30 amp circut breaker (even with 10 gauge wire) sounds dangerous to me.

@lak and that would be .... why?

There are definitely many others much better qualified than me to answer that question. I believe if my memory serves me correctly its been brought up in other threads on Audiogon and it was frowned upon. Hopefully, those other individuals will chime in here.

A dedicated 30 amp circuit (10 guage wiring) costs less than expensive cords and works better than running these wires from a 15 or 20 amp circuit. With this 30 amp circuit, power conditioners are moot.

It isn’t exactly clear what’s being recommended here, but I disagree with it in any event.

First, it isn’t clear what’s meant by a "30 amp circuit." If we’re talking about the U.S., many local electrical codes - including that in my town - would require a 30A receptacle for that circuit. That would then necessitate putting new connectors on the ends of any equipment that would be plugged into that circuit, because a 30A receptacle isn’t compatible with a 15A or 20A plug. That’s a lot of work for something of little potential benefit.

A better solution would be to use 10 gauge wiring, but use a 20A breaker and 20A receptacle, resulting in a "de-rated" circuit. That would comply with both NEC and local code. I’ve done this with my system with great success. ( Some receptacles will not accept 10 gauge wire, but you can use a pigtail if that’s the case.)

However, using such dedicated, de-rated lines is no assurance that the power will be any cleaner than it is at the service panel itself. Under those conditions, there’s no question that a power conditioner can be of great benefit and - for the naysayers in our midst - it’s the sort of thing that can be shown with measurements.

I have a very similar system. Mac C46 pre, Mac mc501 mono blocks , JL audio C1 (really nice device) and a pair of JL audio E112 subs. I have 4 dedicated 20 amp circuits in my audio room and I have a noisy power source (I am on the Philadelphia pa power grid). I can tell you without any reservation that proper use of power conditioning and power cords makes a very big difference. I use a shunyata conditioner for pre-amp, Cr1 crossover and a Bryston DAC with very good results. High current amps are another matter. I plug them directly into wall outlets with shunyata Defenders in spare sockets. I have also been swapping power cords in and out of my system and have found amps most effected. High current cords are necessary to allow the amps to “breath”. The subs have seem not to be as sensitive to power souce and cable. This maybe due to the nature of the built in amps.

good luck
