Best Male & IEC plug for high current power cords?

Far and away, for the best combination of quality and price, Marinco plugs. All copper conductors. Shielding is a waste for power cords. Try Carol 10/3.

Thanks for the input everybody! I found my plugs: Neotech.
Outstanding construction and solid OFC copper conductors -- $50 each through partsconnection.com.

New information about gold plugs. Just got a Black Sands Violet 1 power cord with gold-plated plugs to compare to my BS Violet 1 with copper plugs. The former imparts an mistakenly warmer sound, but seemingly at the expense of clarity. "Voices" seem as though they're coming through a soft cotton scrim. I prefer the neutrality of the copper plugs. CAVEAT: Perhaps I haven't burned in the gold long enough... I'll report back later.

Postscript to the former post: this is my finding when used on my tube dac, not my monoblocks. I'll report back on the difference between the cords on my transport and preamp as well.

I believe the Neotech terminations are identical to FIM.
The FIM label simply covers the Neotech logo molded into the plastic, at least on mine.
The FIMs I've seen are cheaper than $50 per.

I think if you compare the quality of the Furutech FI-11s I mentioned in my post to the Neotech, the Furutech would win hands down. IMO: The Neotechs are somewhat cheesy in overall build, especially the cable clamping mechanism. Have you actually compared the two?

I do like the Neotech bulk power cable though. Very nice quality!
