What is best as wall plug : HMS Furutech Oyaide please

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.)       

I use the Shunyata wall outlets.  It is cryo-ed, the same outlets on their conditioners and cost less than 100 bucks.

Recently purchased a Synergistic Research Telsa SE that I'm very happy with. The best $100 improvement I've made in the system. 

Hi All,

i read your numerous answers and I wish to thank of all you for your great and such kind answers.
i will try furutech gold and rhodium model. Gold was advice by my cable provider. His plugs  are in gold too...
in parallel I strongly advice you to use some oil on the connectors such as Drop oil from Charlin, à french provider. This oil is usable on power cable and modulation cable. LS too. Never on rj45 cable. As you know the aeronautic industry is using such a kind oil in their cable connections. Thanks again for all your answers,
all the best in music !

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.
