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?

Oyaide WPC-Z and Z2...... High performance mounting frame and panel....The appearance of the WPC-Z attracted audio enthusiasts and created a strong impression of mounting frame for wall outlets. In 2007, the long awaited double type base, WPC-Z2, has come on the scene. The most important function for high performance mounting frame is attenuating vibration dampening property. The hybrid materials , each of them has different resonance frequency, perform passive vibration suppression to maximize performance of the Furutech GTX -D-R .Furthermore, carbon fiber reinforced plastic, the material of face plate, has functions of static protection and electromagnetic shielding WPC-Z series are the ultimate optional accessory for unlocking unlimited potential of the Furutech GTX D-R.
I recently replaced my old $5 hospital grade outlets with $100 Oyaide R1's and replaced my old dedicated line comprised of 13 ga Romex with cryo'ed 10. The improvement; minimal. "Minimal" as in de minimus.  I have resolving gear-ARC Ref 6 and Ref 150 SE, Cardas Beyond cabling, etc. Carbon fiber face plates and tuned mounting boxes? C'mon Dude. Why not go the next step and replace the stud the mounting box is attached to with some harmonically tuned 2 by 4 made of ancient dried ebony wood? And the drywall should be replaced too before it introduces bad resonances since the box and plate are mounted flush with the drywall. Maybe it ought to be carbon fiber too. This sounds like the parody of Madison Avenue ad copy; " the ultimate optional accessory for unlocking unlimited potential of the Furutech GTX D-R.". I have an open mind and have implemented tons of tweaks, but this is Tice-Clock goofiness. 
@fsonicsmith .............. First of all i am only giving you MY opinion on what i did hear. And the result was ALOT more than minimal. I wrote my findings as mentioned above. I too have resolving gear. Arc Ref 6, Krell FPB 600, Rega Isis cdp. Straightwire Crescendos from speaker cable quad wired to my B&W 800 Matrix , Straightwire Crescendos XLR ICS. Shunyata Sigma HC PC , Shunyata Sigma Digital PC. Shunyata King Cobra CX. Second of all i am also using Furutech GTX -D-R with my Oyaide aluminum base and carbon fiber plates. You are giving you opinion on yours as minimal.. Thats what you are using as i am not using what you are number 1. And i dont have to keep switching outlets and plates back and forth to my judgement ....I know what i have heard before i switched. And what i am hearing now. You sound like a skeptic about those who are using SR Blue fuses  Some of those people make judgments and have not even tried them. Does that sound familiar DUDE? 
@dynaquest4...... Yes i am having alot of fun... I am trying to get the cleanest purest sound that i can and to bring out the very best in all my equipment like we all try to do. I am only telling what i have heard to my ears. And that was more than very subtle... I dont have to keep switching duplexes back and forth to hear the difference. Besides It is a small job to keep wiring and rewiring duplexes and the Alum case and plate and keep going back and forth. Like i said i know my system and have been hearing it before i installed the Furutech GTX D- R and the Oyaides.... I heard the more than minimal improvement the first time i put on a cd. Sounds really unbelievable but its true and i will put my life on that.  I also am not looking to or for a debate.as every one hears things different and every one has their own opinion... All i am saying is this is what i heard... 
@folkfreak ..........Dont know what you mean about your carbon fiber face plate vibrating... I had no problem with the center hole screw tightening or stripping.... It tightened very well and very secure with no vibration. I also used the Furutech GTX D-R.. Not the SR. Maybe they are somewhat different. 
@tattooedtrackman agreed it feels tight but the fact is the only thing supporting the faceplate the screw in the middle and the pressure against the frame around. The faceplate can vibrate relative to the surround at the edges and damping this is worth a try if you have some materials on hand. Glad the Furutech outlets have better screws then SR however
