Replacing generic RECEPTACLES

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. 

And don't forget to give those fresh new receptacles at least a 100 hour burn-in! LOL!

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. 

Or does it have to be only a 15 amp receptacle on a 15 amp line.
