Nakamichi GrubLock Excel Series 24k Gold Plated Banana Plugs, 10-18 AWG

Nakamichi is a legendary audio brand and these banana plugs are excellent. The design is simple and effective making installation a breeze no matter what gauge wires you use, tinned ends or not. The machining and finish is perfect, with the each little screw fitting precisely. Providing spare screws was a nice touch too.

These are really well made banana plugs, very robust. They make a very secure, tight connection to the 12 awg Monster speaker cable I'm using. This type of connection expands into the amplifier terminal when you plug it in and makes a really reliable, multi-surface connection. Highly recommended!

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.

Nice quality, solid connection. Even included a bunch of spare set screws. Can't ask for much more.

If it were safe and convenient to solder behind my Marantz Cinema 30, I would have opted for a more robust banana plug, but these work fairly well for what they are. Honestly, if they were a little longer and had a third screw so you could use two on the bare wire and the third on the sheathing, I'd give them five stars. Really prefer to have some strain relief, so I opted to use only one screw to cinch the bare wire. The housing is quite thin, so it's easy to drop a screw when trying to get the head flush with the inside. Just not much thread, so best to work with lots of light, and if you need them, reader glasses as being able to focus about 6" from your face helps a lot when it comes to backing the screws out flush, not going that extra bit that drops the screw on the floor. Once you work out the exact length to strip your wire, you'll find doing even a multi-speaker setup fast and easy. For me, these work reasonably well.

Really easy to use and very high quality. The connection goes in solid as well. Can’t go wrong with em

These banana plugs worked well with the cable. The two screws were easy to loosen and then tighten. It is a nice gesture that Nakamichi includes extra screws in case some get lost. Overall a good product and did the job.

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.

Excellent product. Best buy.

3.5sqのケーブルは普通に入り、しっかり留まります。もっと太いケーブルを留めるための短い芋ネジが付属しています。

Well made. They fit nice and tight into the speaker terminals of a Yamaha amp.

Es la primera vez que pongo bananas en mis altavoces y me gustó mucho lo fácil de poner los cables con los dos tornillos buena calidad nakamichi entran perfectas en mis polk es15 signature traen tornillos para cables más gruesos y uno de repuesto muy contento buen precio compraré más gracias

Ho mandato a ritirare questo set da 8 connettori a banana (4 positivi e 4 negativi) per la connessione dei miei nuovi diffusori Elac Debut 2.0 B6.2 al mio amplificatore Marantz PM-50. Ho provveduto ad acquistare un cavo da 5 metri SC-Orbit 240 MKII nella variante da 2x4mm² di Sommer Cable e successivamente a dividerlo in 2 ottenendo quindi x2 cavi da 2,5m. In ultimo ho provveduto a terminare le estremità con le suddette banane Nakamichi (8-16AWG) appunto placcate in oro 24k. Il set arriva in una piacevole bustina in plastica contenente a sua volte altre 3 buste con all'interno 4 connettori positivi contrassegnati in rosso, 4 poli negativi in colore nero ed una vite di serraggio aggiuntiva nel caso in cui se ne perdesse una di quelle già innestate nel connettore. Troviamo anche un piccolo foglio con le istruzioni per una corretta connessione delle banane al cavo. Le dimensioni dei connettori sono come da descrizione e sono perfettamente compatibili con cavi da 8 a 16 AWG. Appunto come da istruzioni riportate sulla confezione ho provveduto a spellare di circa 14mm le parti terminali del cavo e successivamente a connettere le banane. Il connettore è dotato di 2 viti di serraggio, una nella parte alta ed una nella parte bassa, che garantiscono un'ottima tenuta del cavo resistendo con efficacia a strattoni e risultando efficace nel sorreggere il peso del cavo stesso quando connesse al diffusore / amplificatore. Raccomando di non esagerare col serraggio, soprattutto se si utilizza un cavo dalla sezione di 4mm, è necessario un serraggio deciso ma non eccessivo onde evitare di danneggiare il cavo al loro interno. Il risultato è stato più che soddisfacente come da foto allegate alla recensione. Ho avvertito un leggero miglioramento in termini di pulizia e qualità del segnale e le trovo davvero molto comode per innesti e disconnessioni rapide e semplici. Una menzione speciale anche al design che reputo molto accattivante, almeno a me piacciono davvero molto. Un set che sento di consigliare per l'ottima funzionalità e qualità generale e che reputo dal prezzo di vendita corretto. Approvate a pieni voti! Aggiornamento al 30/01/2023: Ho notato che i cappucci a vite tendono ad allentarsi con le vibrazioni fino a svitarsi del tutto. Riscontro il problema soltanto con le banane connesse ai diffusori. Ho provveduto a fissarli con un goccio di frena filetti. A parte questo dettaglio confermo quanto già detto in recensione.
