Replacing generic RECEPTACLES

tecnik........ I can not do the Furutech FI-09 Rhodium IECs as i am using Shunyata King Cobra and Sigmas. 

Not sure i know what you mean by needs to be on the same leg of the service panel as my 20A dedicated line, same phase. And what do you mean by appliances? blender ? microwave? toaster? Im not trying to be funny but i have a dedicated listening room. Its not in my kitchen.

The wiring in a residence is called split-phase and is divided into 2 legs. On the service panel you will see Leg A and Leg B. The goal in the panel is to even out the load, half the current draw on A and half on B. If you wire a refrigerator on A, then a second high current appliance such as air conditioning should be wired to B.

Simply put, In an audio system, we want all the components on the same leg so there is minimal noise from other devices wired into the panel. 
And yes, I am talking about toaster, blender, refrigerator; all adding noise and interference down the AC line and contaminating the other circuits.
Electricians are only concerned with balancing the current draw in the house, so roughly half from Leg A and half from Leg B. And they commonly will daisy chain several AC outlets onto the same breaker. The kitchen toaster outlet may be combined with the lights in your living room.

If some of your audio system is wired to A and some to B, there is more risk of noise from the circuits in the other leg of the panel getting into your audio lines.

A test for a shared line is to turn off the breaker to your CDP and see what other outlets in your house lose power.

@lowrider57 ........ I understand what you are talking about now.... You explained it very well.. And yes the CDP is on the same leg as my dedicated 20A line for my amp and preamp. I understand them now going on the same leg but like you mentioned both legs should be evened out. Lets say leg A has the Refrigerator, Jacuzzi, AC , TV.Microwave, and leg B has a tanning bed , big screen tv, and 2 ACs. Now both legs have appliances , so explain to me what that matters then. I understand u want to keep all the audio components on the same leg but if there are appliances on both legs why would it matter. Curious.... 

@elizabeth is exactly right.
To take this concept further, the ideal setup of the service panel for cleaner audio would be to have your dedicated audio breakers grouped together at the top of the panel. Or at the bottom, if that's where the wiring enters.

So, if the lines enter at the top, your audio lines would be in the first breakers, same leg. Then the heavy duty appliances that you listed would be far away near the bottom split between Legs A and B. The theory being that the noise introduced into the panel would not be close to the audio breakers.
But, since the grounds and neutrals are shared, noise will still contaminate the rest of the panel to a lesser extent.

To take noise reduction even further, many audiophiles use a subpanel for their audio lines. This is a smaller dedicated circuit box attached to the main service panel. 
When I expanded my system (which is very modest), I received step by step advise from our most experienced members on how to do this in my house. Now that I have a subpanel which has it's own ground and is tied to the service panel, the noise floor at my audio setup is extremely low. It helped in my case because I live in a prewar row home with a mix of old and new wiring.

If you had all new electrical installed in your home and the distribution of current draw is laid out well, you will be in very good shape with 2 dedicated lines. If you run that 2nd line, move it close to line #1 on the same leg.
