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? 
elizabeth...Thanks...But can u answer me this? I thought it would be dangerous if you used a 15a receptacle on a 20 a line, not a 20a receptacle on a 15a line. In my opinion it would be less voltage going into a 20 a receptacle on a 15 a line. But what do i know.

I was always confused about this..... I am no electrician.So dont laugh.  Can i use a 20a Furutech GTX-D-R receptacle on a 15 amp line for my cdp Or does it have to be a 20 amp line while using a 20 amp receptacle. 
And don't forget to give those fresh new receptacles at least a 100 hour burn-in! LOL!

lowrider57......... I have a dedicated line for my Krell FPB 600 amp and my ARC Ref 6 preamp which i will be adding the Furutech GTX-d r. But not for my Rega Isis cdp. Would you also recommend a dedicated line for the cdp too? I was just going to change the generic receptacle to the Furutech GTX-d r. 
Get al Furutech they are among the best.Why would you plug a system into a $1.00 outlet??
Yes, upgrade outlets for sure over the average outlet you find in your home. How much you spend and the brand you purchase is a personal choice.
Thanks.... Just bought a couple of Furutech GTX -D -Rhodium from a very nice seller on here. Will be buying at least 1 more from him .
Yes, for a duplex under $50.00 I recommend Porter Ports available from Albert Porter here on AudiogoN. For more expensive offerings checkout Furutech and Oyaide outlets at VH Audio.
