Nakamichi Excel Series 24k Gold Plated Banana Plug 12 AWG - 18 AWG Gauge Size 4mm for Speakers Amplifier Hi-Fi AV Receiver Stereo Home Theatre Radio Audio Wire Cable Screw Connector 8 Pcs (4-Pairs)

Considering the reputation of Nakamichi and the fact these were less than $8 I was dubious about getting authentic parts. After using them the quality seems top-notch in every way with none of the aberrations typical of cheap imitations (poor quality uneven branding/silk screening, burrs, poor machining causing gritty, uneven screw connections and driver slots that aren't deep enough, uneven depth/width, misfitting parts, inconsistent sizing, etc). These look great, work great, fit great; it's a simple part and I think the price is reasonable but some brands are over 2x the cost and I can't see them being 2x the quality and some generic parts are the same cost and I can't see them matching this quality, I only found one about $1 cheaper from some no-name Chinese manufacturer and if these aren't genuine Japanese parts they're outsourced to a higher quality standard that is up to Nakamichi's audiophile quality reputation.

Excellent quality for the price. The two screws are essential for a tight grip. I used on 14 gauge speaker Wire. Anything other than direct solder is only going to squish the wire unevenly. Easy to install.

If you're looking for a straightforward way to improve your audio setup, these banana plugs are a great choice. They're well-made, easy to install, and deliver on their promise of improved conductivity.The gold plating ensures a secure connection, and the build quality feels solid.

Pricey but work very well.

Completely satisfied, quality terminal. They also come with 10G set screws if you need them.

I bought these because my Yamaha R-N800A, like other Yamaha amps I've used, has one glaring flaw: really crappy speaker wire terminals. They are flimsy-feeling, not very well textured plastic, and they are way too close together. As a result, it's tough to get bare wire really set firmly into them; to the point that after a few weeks the right channel was cutting out because the terminal had come lose and was allowing play in the wire connection.I ended up choosing these banana plugs because of the cool look and a fondness for the Nakamichi name from my youth. They were very easy to set-up and firmly clamp down on the wire with dual set-screws. The plugs seat very firmly into to speaker terminals. (In fact, at first I thought maybe I had somehow bought some strange, unknown size that wouldn't fit. Nope. Tjhey're just that snug.) And, IMO, they did end up looking cool installed.As for performance, these kind of things are... for me... oh so hard to tell. But I do think I noticed a widened sound stage with these in place. Perhaps not. And perhaps that wouldn't be the case with amps that have better speaker terminals than Yamaha's. But I do believe it to be true.I would buy these again without thinking twice.

Great products, easy to install and use.
