Dedicated Circuit - Quad Receptacle Question

Yep, best to have two dedicated lines, one for analog and one for digital, as long as you (and your electrician) follow Jea48's recommendation to place both on the same phase of the electrical service. Also, have the electrician move the circuit breakers in your breaker box around such that noisy appliances (AC, refrigerator, microwave, etc) are on the phase opposite the audio lines.

Also, don't gloss over the importance of receptacles. They make a big difference in the sound of your equipment and will influence your selection of power cords. My favorite receptacles are the Porter Port ($36 on Agon) and the Synergistic Research TeslaPlex ($95 from any SR dealer).

Dlcockrum, you mentioned having the appliances on the phase opposite the audio lines.

If my music room breaker is on the left side of the panel, and all noisy stuff is on the right side (AC, washer, dryer, fridge), is this already a done deal?

Theunderlyingtheme,

L1 and L2 alternate every other breaker down each side of the electrical panel.
Here is a diagram Glen B, a member of AA , supplied in a post.

You should not load up one leg, line, with all the 120V heavy load appliances. The 120V loads on L1 and L2 of the panel should be somewhat balanced.

Best you can do is make sure the breakers for the new dedicated circuits are not directly across from appliance load breakers and not directly above or below noisy loads.
