Replacing generic RECEPTACLES


How important is it to replace your generic receptacles with audio grade receptacles . I already replaced my stock power cords to high end Shunyatas. Would it still be necessary to still change my generic receptacles to audio grade?

Also when my electrician installed my dedicated 20a line for my amp and preamp he also installed a quad {4} outlet receptacle. Would this still be considered a dedicated line for my amp and preamp?

it looks to me like replacing a healthy tooth with nicer looking one. many celebrities do that.
czarivey....No u are wrong. My cdp is not on a dedicated line. So i will be adding a dedicated line for that. But i already bought a Furutech GTX-d r 20 amp. At first i thought i could use it for my non dedicated 15a line with my Furutech GTX-d r . But not according to Elizabeth if i am reading her answer right.  But since i want to have a dedicated line for my cdp i might as well go with a 20a dedicated line so i can use my 20 a Furutech with my cdp. Does this make sense?
