NakamichiUltimate Series 24k Gold Plated Beryllium Red Copper Banana Plug 12 AWG - 18 AWG Gauge Size 4mm for Speakers Amplifier Hi-Fi Stereo Receiver Audio Wire Cable Connector 4 Pcs (2-Pairs)

I bought these hoping for an upgrade after one my old banana plugs - also Nakamichis, but the regular gold-plated ones, so cheaper than these - came apart. I use banana plugs at both ends - speakers and amp.These fancy berillium ones look the part and weigh quite a bit so they feel like quality banana plugs, but that's about all they get right. They're very fiddly to fit - once you've got the cable end in place and clamped it in place by tightening both screws, it's then really difficult to screw the jacket/cover on. Maybe my cable was a bit too thick for these, but I never had that issue with my old Nakamichi plugs.With a pair of pliers, a bit of persistence and some choice language, I eventually got them on, so I plugged them into the amp and speakers, sat back and played some mucis, expecting to enjoy the rewards of my efforts. But no, things went from bad to worse: the sound was very noticably impaired compared to how it had been with the old plugs; the frequency extremese were rolled off, so really deep bass and top-end (hi-hats, cymbals, etc) were muted, and the whole presentation just seemed a bit veiled, a bit less clear and sharp than it had been.I gave them a chance, stuck with them for a week or so, then decided I'd had enough. I took them off and went right back to basics, did away with plugs altogether and just went bare-cable-ends to amp/speaker terminals. And voila, clarity and presence were back in abundance.If you've got a system that needs taming - maybe too bright in the treble, or too boomy in the low bass - then these might be just what you need. But you will also lose some clarity and detail too.

These were perfect. I used a proper fitting screwdriver and it went very well. Thanks

Ottimo prodotto, si serrano bene sui cavi, tengono bene sugli innesti, consigliati per cavi dal diametro 4mmq.

Cómo siempre, calidad de excelencia para un precio razonable. Muy recomendables.

Je nach Dicke des Kabels war es einfach die Stecker anzubringen.Bei zu dickem Kabel sollte man nach anderen suchen.

Da questa marca, mi sarei aspettato di molto meglio. I connettori sono validi, ma le filettature di alcuni, fanno veramente pena. Non molto soddisfatto
