Default Re: Warning: Nakamichi plugs "Not made of copper"

Slight attraction to magnet, the pot-metal mix is more likely. And I don't have a geiger counter...heck, not even some old fashion film around the house to test that idea! Conductively they'll work for the project I am using them which is more show than sound. Problem is that most bent spades are bent at an angle around 30 from the mounting plane; I like mine bent more like 60 - 75 (on wall plates ~90). Pot metal or whatever, bend = snap. The other problem at least with the some of the spades I ordered is the inside spade width is ~7.5mm, bend it out a bit to fit a regular 8mm binding post and...snap. Just wanted to get the word out to the community...the company did refund my money after I sent them a photo.

ya know...there are RCA's sold with the Nak name. I wonder if those are similar in construction. I see them all over the net.

I recently got some Nakamichi plugs (ebay) and I was very disatisfied with them.
This was for a topping TP20-mk2 amp.

So, I got a 2 pair of very good "closed screw" type plugs from PE and they are great.
They are solidly designed and constucted. They are also very inexpensive.

I wound up soldering the speaker wires to them for a very secure connection even though it was not nessary.

For only $1.23 each when QTY 50+ purchased - 1 PAIR OF High-Quality Copper Speaker Banana Plugs - Closed Screw Type [JX-74043] | Banana Plugs

heh..., Who bought Naka plugs and test ? How to test? I bought Naka BFA banana plugs. They seem good. The sound also very good. BFA plugs not stick to magnets.

I am ABSOLUTELY SHOCKED that the "Nakamichi" banana plugs I got off of Ebay for $2 a pair shipped from China aren't legit. The set screw strips immediately, as cheap as they come. I still like them better than the cheap parts express bananas, though.

Just to add to the discussion, here are another fake banana plugs on eBay.co.uk: "4xHigh Quality,heavy duty real pure copper connector body SPEAKER BANANA #JT010"

URl Link: 4xHigh Quality,heavy duty real pure copper connector body SPEAKER BANANA #JT010 | eBay

I purchased 8 of them and quality is horrible, two where loose, and after one screw snapped broken, I became concerned with the copper content in it. I have cut through its body and under its plating, you guessed now, - Aluminium or shiny color metal and NO copper!

I have seen several postings on this forum and others about using Nakamichi banana plugs and other connectors, and wanted to let folks know that they are an overpriced piece of gold plated iron. Hey, they look nice, and the moderate price would make one think that they're getting a good deal. Nope.

Discovered by breaking a tip on a spade plug trying to get it to fit an 8mm post; copper doesn't snap like that and upon magnification is definitely not copper by looks. Filed down that piece, and sample filings on other pieces and also some banana plugs, discovered all were a gold plating on copper plating on soft iron. Finally verified it by dropping it in some hydrochloric acid, and as expected the iron reacted (slowly). (Don't have any nitric acid to test with which is very reactive with copper but not as much with iron.)

FYI.
Original Nakamichi banana plugs or RCA plugs have never manufactured in iron or steel.
It just looks like you are looking to give Nakamichi bad advertising.
