Audio Connectors, etc.

The quality of the connector is usually underestimated. But we know from experience how much sonic difference there is between a tight connection and a pair of surfaces that are just "touching."

The Eichmann "bayonet" banana
Why the bayonet name? It's the way the shell fits together, with a simple twist. The bayonet plug uses minimum metal, to minimize magnetic effects, and its spring action provides a tight connection in most binding posts. It can be fastened to a cable by crimping (with an arropriate crimping tool of course), or by soldering. Then twist on the blue shell, and tighten the two set screws to provide strain relief.

Eichmann spade terminals
New from the company that invented high-performance minimalist connectors -- spade terminals made from either pure copper plated with gold, or pure silver. There is even a narrow spade designed for barrier terminals, such as those found on McIntosh amplifiers and Vandersteen loudspeakers. The size indicates the "mouth" opening of the spade. All are designed to be soldered.

Furutech bananas and spades


These beautifully-made connectors for speaker cables are made of copper, which is silver-plated, and then rhodium-plated over that for scratch-resistance. The banana tightens under pressure, much like the WBT-0645, and you connect the wire the same way as you would the WBT (see below). The space fastens to a cable the same way, and it's the first affordable spade connector we have seen in a long time. Both are highly recommended. The connection is best made by using WBT gold sleeves over the best wire end, crimped with the WBT-0403 crimping tool (scroll down to see the WBT products). Buy the tool at the same time as the connectors, and we'll buy it back when you're through.

J. A. Michell Binding Posts
The posts shown above are a great way to upgrade the sound of your speakers or amplifier. The post at right is the aptly named Big Mother, which takes bare wires, spades and banana plugs, and establishes a firm contact. The long shank allows you to mount them right in a thick wood cabinet. We have it plated with gold (non-tarnishing, superb conductor) or rhodium (also non-tarnishing, much tougher than gold). For amplifiers, or for speakers with little rear clearance, the Eichmann Cable Pods (below) are an excellent choice.

Eichmann Cable Pods
Eichmann is now famous for its outstanding connectors using the strict minimum of metal, and good metal (tellurium copper, 24K gold plated) at that. Now come the Cable Pods, replacements for the binding posts on speakers or amplifiers. It mounts in panels with thickness ranging from 1mm to 10mm. The blue panel can be removed if your mounting holes are not the standard distance apart. A non-rotating washer makes it easy to tighten them against a spade. They'll take a banana (just pop off the safety cap), spade or bare wire. You can solder the wire, or -- this is unique -- you can actually connect to the rear with a banana, and no solder needed!

WBT connectors
  • The banana connectors above are the best we know of. Tighten them, and they'll grip under so much pressure you could lift your speaker by the cable?

    Look at the connectors shown above. Tighten the collar on the banana plug, and it spreads so that it holds tightly even in a mediocre jack. Turn the barrel on the phono plug, and two things happen. The tip opens up, and the coaxial collar tightens. Both apply so much pressure that you could actually lift a heavy amplifier by its cable!

    You can buy UHF's own cables with WBT connectors attached (see Cables), or you can buy the connectors and install them yourself.

    Numerous connectors are available:

    • WBT-0108 RCA connector (4) for crimping $190 Click to buy
    • WBT-0144 RCA Midline connectors (4) for soldering, $90 Click to buy
    • WBT-0600 banana connectors (4) $180 Click to buy
    • WBT-0644 Midline banana connectors (4) $90 Click to buy
    • WBT-0645 Midline angled banana connector (4) $110 Click to buy

    Midlines have a matte black barrel, three layers of gold plating instead of five, slightly looser machining tolerances, and 52% copper instead of 68% oxygen-free copper. And a much lower price! The newest version is the one shown below, angled for bi- or tri-wiring. The knurled button at the back includes a jack, so you can plug one banana into the other.

    We recommend "crimping" connectors, which require no solder. You buy appropriate gold sleeves, which you must crimp onto the wire end. Sizes shown are the area of the opening in the sleeve.

    To crimp a sleeve onto the bare wire, you need WBT's special crimping tool, WBT-0403, $125. When you're through, if you also purchased your connectors from us, send it back, and we'll buy it back at the price you paid. Click to buy

    A two-way adapter
    Need to connect two cables to one jack? You do if you have a subwoofer or a video system. Or if you want to biamplify. Our FYA adapter, for $20 a pair, is gold-plated and is insulated with Teflon.

    For tightening connectors
    If your speaker or preamplifier binding posts are hexagonal (either 1/2" or 7/16"), finger-tightening them is not enough. A wrench will do the trick, but can easily snap the post right off (we...er, know what we are talking about). We heartily recommend the Dynaclear Postman, a phenolic wrench that is perfect for the job. Retighten with this once a month, and you'll be amazed at the difference. Indispensable!

    ProGold connector treatment
    We know people who use alcohol to clean their connectors. We don't advise it, because alcohol is corrosive, and so the improvement is short-lived. We use ProGold, which not only removes oxidation, but slows its buildup, and actually improves conductivity. ProGold is used in aerospace and marine applications as well as Audio and video.The PGW kit is a box of small wipes, which can be used to clean accessible connector surfaces. We also use the PGS spray can, which squirts ProGold onto surfaces you cant get at with wipes.

    Wako-Tech silver solder
    If you plan to solder a critical audio connection, get this extra-conductive 4% silver-content solder, from the same people who make the Enacom AC filter and Harmonix components. It's totally lead-free, with silver of exceptional purity, greater strength than other "audiophile" solders, and chlorine-free flux to reduce corrosion. We've been using this solder ourselves for years.
