Has anyone upgraded power cord connectors?

Subaruguru, I beg to differ as the connectors make up at least fifty percent of the "sound" of a power inlet cord.

This is hearsay from another member, but when he replaced the chintsy plug on his AC cord the improvement was reportedly significant. Based upon my experience with the Wattgate 381 AC outlet, if replacing male AC plugs with Wattgate's product approaches anywhere near the improvement that the 381 accomplished, then you'd be a fool to not do so. But this is only an extrapolated opinion, I haven't tried that although I certainly should.

Hi!

The first choice are the ones with COPPER contacts (hard to find), second choice would be the ones with brass contacts. Avoid any plating.
The connectors must not be expensive as long as the contacts are of the above mentioned materials.

David d, I don't know where you find copper AC connectors as the better ones all seem to be Olin 688 brass, an alloy which is about 73-75% copper.....The problem with most of these is that the screws and tines on the neutral side are nickel plated and these cost like the devil to have them remade in the 688 brass, so much that I named my new cord the "688" model....

Hi, Rcrump!

Sorry! I applied more to the IEC connectors. I think that the German firm Phonosophie have the contacts on their cables made from copper(very likely a special order), though. It must be possible to find them (AC connectors with copper contacts) somewhere...
Your'e right the nickel plating is a very bad thing(soundwise). Perhaps you can "get rid" of the nickel plating with abrasive paper or something else?

By the way, can you tell me more about the design of your new PC cord "688" model?
Maybe we should start a new thread about (DIY) PC?

Best regards,
David.
