Dedicated circuits

Very good comments. I have been an advocate of high quality AC power for audio components for a long time. I have also recognized that the need for ultra high current capability is grossly exaggerated when discussed on audiophile forums. People take it too far and over the top.

You and @dpop provide very rational examples and explanations as to why there’s no need or supportive evidence to go overboard with regard to having sufficient amounts of electrical current available. The “headroom “  argument can be over inflated.

I, too, waited too long to upgrade the electrical path.  Skeptical of SQ improvement.  Well worth it.  Hearing is believing.  Especially if your system is true to the source.

Voltage drop allowances are not even a NEC requirement, I know I've had voltage drop with my system when I used a carver subwoofer for a short time, even with 20 amp dedicated circuits using 10awg wire.

If I recall, the Carver subs substituted power for size, so a ferocious amount of power was demanded.  Not that surprised.  :-)   A large diameter sub would fix that.

I believe in isolation of power to my audio system. I installed 3 dedicated lines for my system. I used 10ga romex for amp, 12 ga for preamp and another 12ga for digital.  I used 20amp breaker for the amp and 15 amp breakers for the other two lines. All my components have robust power supplies supplying the needs of the audio curcuits therin. I believe the current supplied is more than sufficient.  Also used hospital grade outlets for all lines. Lines are rum off a subpanel that, in addition, only serves  bedroom outlets and lights.
