If your powercord. Is aQuality brand then go for it , for the lower the number the
thicker the guage awg 10 is good lower resistance ,another bottle neck
could be what do you have it plugged into ,that too might’ve restricting it
and a dedicated 4 wire 20 amp line would be good witha common ground and separate isolated ground on its own buzz bar grounded , for line conditioner
you have to make sure it can handle the load ,how many watts per channel is your amp ? Is it a dedicated separate amp, power amp ? I sh h the sourse, then preamp
goon first then the amplifier, and when shutting off in reverse order.
