What is best as wall plug : HMS Furutech Oyaide please

I used common wall AC duplex for many years and was totally happy with them. My personal favorite was Pass & Seymour brand heavy duty 20amp. Other like Hubble hospital. (though many say the current Hubble Hospital are not any better anymore).          
Then the 'middle' priced duplex: Cryoed, Acme silver.. Several in the $50 range. And then the Oyaide and Frutech at $80 to $280.As for buying them? I would say the op would be happy with a $6 Pass & Seymour duplex.  
For plugs. I used to like Wattgate. but they are just basic plugs. At $13 for the male Edison type, and $20 for the IEC. they are entry level.  
IMO to actually buy the expensive separate plugs from Furutech or Oyaide, the cost plus wire in just makes no sense (from a 'bang for your buck' perspective) ... Go BUY a fully finished aftermarket power cord. Shuyata, Pangea. Some low cost entry powercord. Unless you just have to try them out..

auxinput mentions outlets as tone controls. One thing I have found since I went to all Furutech duplex, is that common brass outlet parts/plugs (with no plating) are actually pretty bad! They harm the sound. You never know this until you are rid of them! 
Having gotten rid of them, then trying some, yikes! they are terrible. naturally only in a tiny audiophile ear killing way. (normal folks would never notice anything different IMO).The other thing is I originally liked the gold plated Furutech GTX better ... at first. but as time goes on(for weeks for some new duplex) I am happier with the sound of equipment plugged into the Rhodium GTX NCF duplex. Just a little better detail, tiny bit smoother highs.( I cannot say if this is due to the NCF. Since no gold Furutech Duplex use it yet.)       

Remember the Rhodium takes many hours to sound it's best. and it will seem good then go back to being thin sound and accent the treble, back and forth until it settles down. Two weeks in and still changes back and forth. Otherwise much better. Just be prepared for the long break in. (or run the outlet on an appliance for a month!) I Googled the oil you mention. I would probably buy the Furutech product like it.
