Viborg BP603 4X HiFi Speaker Binding Post Pure Copper Hi-end Speaker Banana Plug Socket Terminals Screw Lock Audiophile Banana Jack Connectors, Eutectic Copper Alloy Shell, for HiFi Speaker Amplifier

Headline says it all. There are "better" ones out there but you have to pay considerably more. I used them to upgrade the jacks on pair of JBL L100's and they were a perfect fit. No drilling in my case.

I don't normally write reviews but as soon as i took these out of the package i was blown away!! Pictures do not do these binding posts justice!! I paired them with a mounting plate off of parts express and they are STUNNING!!! Parts express really dosent have any high quality binding posts but i do like the plate that i purchased so yeah, definitely dont hesitate to grab these. Nothing but 100 percent pure goodness in the signal path!!

I bought these to replace the posts in my Elac UB52's which were garbage with shyte clip connectors to the internal wiring. As soon as I opened the package I was smitten - these are beautifully made, definitely high copper content, and weighty. Probably 3 times the mass of the Elac posts. I stripped the internal wires, set the screw, and heatshrinked the connection to seal it and strengthen the new joint. Piece of cake, and a real upgrade to these already very fine speakers. Haha while I was at it I lined the boxes with dynamat and replaced the stock polyfill with some acoustic foam! I can't honestly say the sound has improved, but I hae no doubt that it has. These are a great value in high end binding posts, I don't think I'd see any further gains with Furutech.

These are, bar none, the best binding posts I've ever used. I was pleasantly surprised to find them on Amazon at a better price than I've paid in the past at another supplier!!I've used these on Heresy and Cornwall rebuilds, subwoofer projects and test equipment, and they're the best quality, most rugged, dependable and electrically transparent posts I've used, including the so-called "esoteric" offerings. I've even used them as motorcycle battery charger quick-disconnects!!Don't waste your money on things you can't hear!! Get these. You WON'T be disappointed.

Upgraded my terminals on my JBL 4312 from 2mm/wire connections to these 4mm/ banana plug connections. As you can see in the pictures it fits my canarse plugs perfect. So far they sound good and are sturdy from the new holes i drilled in my cabinet. I would give it 5 stars but I’ve only had these installed for 5 minutes and I can’t give a long term review yet.

I like that they're pure Cooper and contains no magnetic parts so it won't degrade the signal. I used them to replace the binding post of my Polk speakers. I also upgraded the crossovers to Jantzen poly caps,high grade resistors and 12 gage OFC wires. So these binding post was well worth it. Now my speakers sound awesome the clarity and detail retrieval are way beyond the next level. I highly recommend these binding post if you are truly looking to get the best signal transfer to your speakers or Amp.

I highly recommend these binding posts for anyone looking to upgrade existing posts that need to fit in a rather thick baffle. We are building custom cabinets for my 1982 Klipsch Heresy speakers and I purchased these as an upgrade for that project. The build quality is excellent, shiny copper finish, black aluminum caps with color coding rings, hex key wire tightening screw, clear and color coded insulators.

I build lots of diy speakers and prefer solid copper binding posts, but they tend to be very costly. These posts are by far the best quality per dollar I have ever seen. Solid copper with an integrated copper collar, with a set screw at the base to accept wire. Very heavy and threads feel great. Top shelf posts.
