Eventually frequency is impacted by gauge but not always in a good way. I would be more concerned with downstream electronics not being able to blow a huge breaker when in distress. Unless it is some one off like that monster Amp pictured I would not exceed 12 gauge 20 amp service for stereo gear. For the huge 30 AMP monster AMP I would run dedicated circuit with dedicated breaker. It already has a 30 AMP NEMA plug to prevent plugging into a standard 110 outlet.
Do I need 10 gauge power cord if I have 10 gauge from panel?
I just installed some dedicated circuits with 10 gauge electrical wire. But now I have to consider replacing my amp power cords because they are 14 gauge or higher.
Is this really necessary and any recommendations on quality 10 gauge power cords that I should buy?
