4PCS Spade Connector,45 Degree Pure Copper Audio Fork Y Spade Plug DIY with Heat Shrink Tubing and Hex Wrench,Double Screw Locking Speaker Cable Plug for Speaker Cables

Copper is better than brass, simple fact. However, long ago somebody decided to use brass because it's more durable? This is about hifi neurosis not a month in Ukraine. Copper doesn't react to a magnet, all the terminals on Audioquest, Blue Jeans, even Mcintosh' $2,500 cables use flippin' brass terminals that stick to a magnet. Say farewell to all that fancy oxygen free copper you paid for as long as you start and end with a metal that's only 77% as conductive as copper. I've had the bare copper on a few pairs for several years here on the salty gulf coast, zero oxidation or any other issue that would suggest their age. The screws hold tight, haven't have any spades or bananas that came loose going from summer to winter over and over. If Blue Jeans could put these on their primo cables using their Star Trek laser welding gadget, I'd pay another $50. Highly recommended, Viborg is the only terminal used in my house with 3 (decent) audio rooms. I have these on AQ Rocket 88/44s and all other brands of cable I've bought over the years, I just removed the factory and put these on. Great low-cost audio hack that actually has science behind it.

Used these spades because another set that I bought, to adapt bananas, for some unknown reason didn't work at all. I had an extra pair of these and they installed and performed just fine. I ordered two more sets to do ALL my connections.

These terminals were easy to install, small Allen wrench does it. Only had one problem ! they clear coated these terminals rendering its performance. Did not work right off the bat and had to sand the surface coat off in order for it to work. :( Other than that they look and feel quality. I also added some extra sleeve on mine.

I was hesitant about these at first, as copper tends to tarnish rapidly, although it is a superior conductor over gold. The heat shrink they supply provides an excellent amount of protection for the metal and the connection. I have the silver banana plugs as well, and they didn't have a bit of tarnish on them after two years thanks to the heat shrink. Some people will prefer silver plated over copper, for me copper has a warmer sound that is still very detailed. These have little allen screws, which is kind of a pain if you don't have the right size allen key but at least they don't strip like flat head screws.

I should have paid attention to the gauge. Wanted them to be a larger but can still use them a the future install

This product has two big problems with it. 1. It has some clear coating that completely prevents continuity. No connectivity at all. You must file off the clear coat in order for them to work. 2. They are not copper underneath the coating. They are brass. This is clearly false advertising. They are beautiful but it's a shame they are not as described.

I use these for several applications. Good to have

Needed something that wouldn't sweat 90A surges and would keep its cool under 50A constant current and this seems to handle the job fine. I just ran it for a few hours and I only got to keep about 5A average current going through it, but it handled the surges fine. Its connected to my car battery to supply my 3KW inverter.

Fitted cables well, great finish, and with the shrink tubing gave a professional finish...
