Best Male & IEC plug for high current power cords?


What are the the best, most cost-effective MALE and IEC plugs for use in high current power cords, with tubes and with SS power amps? Detail, dynamics, balance and BLACK background! No hash or sibilance! ... Copper? Gold? Rhodium? Silver? ... Furutech? Oyaide? Wattgate? ... And the wires, shielded or unshielded?

Update: outside of this forum I just talked to two people, dedicated DIYers, who did a heads-up comparison of the Neotech and Furutech plugs, both of whom found the Neotech to be sonically superior. Neotech copper male and iec, ditto Furutech (F1-11), all else held constant, in a power amp application.
A lot of this stuff is like splitting hairs, that is, the differences can be extremely subtle. Also, the AC outlet and IEC in your components can affect things.

Most audio components use crappy (read cheap) IECs. You might consider replacing those as well in your quest. What outlets are you using?

As to your last post, there are just too many variables involved to make a blanket statement. The bottom line is, whatever works for you. There's certainly nothing "wrong" with the Neotechs, just a few details I personally don't like.
Rja, You're absolutely right about the component iecs. That's my next step. Thanks.
Violet ZII with gold-plated Furutech plugs has finally fully broken in and it works wonders with taming the digititus of my solid state gear but it's not as focused as I'd like with my tube system. It maintains excellent detail with solid state and is wonderfully liquid. I think a standard Violet will be just the ticket for the tube set-up!
I have found unshielded pc sound better with tube amps.
Copper power wall plugs have more realistic bite than silver.
Silver power wall plugs sound more organic on voices.
I made some unshielded power cables with copper wall plugs and silver iec - but they are not optimum for my digital equipment. AND, I am not convinced they are optimum for another tubeamp. It is quite frustrating to figure out what to use. I also have a sense that wattgate may sound a little bit better than furutech on both copper and silver.
Check out "power cable shootout" and good luck.
