    Can anyone tell me if I could connect Silver Anniversary with the Airloc plugs between a pair of W'dales and a Denon 1804 or would it be better keeping one or both ends of the cable bare?:confused:

    Not so keen on the airloc plugs, they're probably really good. But when you can only use them once, and at £5 a throw, I perfer to use normal gold bananas which unscrew instead.

    Bananas keep the ends of the cable tidy, much neater then sticking the bare wire into the speaker and crushing the life outta it!

    Buuut going back to your original question I don't see why you couldn't use banana plugs to connect your kit together (someone correct me if I'm wrong pls).

    Bananas are much easier if you're a fiddler and constantly unplugging your speakers, otherwise there's no benefit over bare wire.

    Unless of course you believe all the rubbish written about standing waves, etc. where the wire connects to the speaker terminal.

    Me too.
    Was a real pain getting 14 pairs of bananas connected but worth it. :D

    I always go for Airlocs - expensive but worth the cost in my opinion. Better than solder or standard screw type banana plugs.

    The newer and more recent Airloc plugs also have a triple crimp around the the cable, better than the older single.

    I second your first comment about them being much better, but you've got me confused about single or triple bits?

    Personnally I prefered the older Airloc bananas as they had a much lower tendancy to fall out of the posts in speakers. They claim a higher surface area now for conducting, but if they're loose it's not a lot of use.

    Must have done hundreds of those old ones...:D

    Not sure I agree with the standing wave theory and all that stuff, but I've been using bare wire connections for some time now and when I recently removed the cable completely from the speakers and amp, the cable ends had sort of oxidised. This would probably have some effect on sound quality wouldent it? and makes me think bananas may help stop this from happening again?

    Its good quality cable by the way.

    Perhaps but even with a banana, the bare cable is still going to oxidise - unless the banana is airtight or you actually solder them...

    Airloc is cold soldered and would stop oxidising.
    They also make a better connection than bare wire and standard banana plugs as there is more contact internally aswell as externally.
    the plug becomes an extension of the cable.

    Airlocs are great until you start fiddling with them regularly. The soft red or black rubber rings around the middle of the plug (showing you positive and negative connections) wear off. Then you have to rely on the cable covering for identification. Bad design IMO.

    surely the quality of the item is much more important than how easy it is to plug them in the once every couple of years the kit gets moved.

    Hi,

    I have just obtained (2nd hand) a pair of speakers, along with some QED Profile Silver 12 cable for bi-wiring, terminated in Airloc connectors.

    For each of the Left and Right cables, the (i assume) speaker end is as i would expect - x4 crimped (Airloc?) QED bannana plugs (2 pos / 2 neg), BUT the (i assume) amp end - has x2 FEMALE Airloc 4mm connectors???

    The female connectors can be seen in the top left picture in the QED link (next to 'NB'): http://www.creative-audio.co.uk/0_CABLES1.htm

    Can anyone tell me how these are used?
    I have never heard of an amplifier with 4mm bannana pegs as an output, and can't imagine one for electrical safety reasons - and yet i can't think how these connectors are designed to be used. Is there a missing double ended 4mm bannana plug fitting missing that is placed between the female plug and the amp's female plug (makes no sense - as why not just use a normal male plug)?

    Any reply regarding this seemingly strange query would be greatly appreciated (even if the answer makes me feel particulalry retarded).

    It looks like im just going to end up cutting off these female plugs and attaching a pair (or x4) normal bannana plugs, but i'd like to understand what going on here with the female plugs first.

    Yours, very confused, Mark.

    Well, my fiance has just come up with a seemingly obvious answer - that they are extention cables, so the extending section starts with a female plug.

    But, why would a company like QED advocate joining speaker cables together and nearly doubling the number of physical connections (original plug to extender plug, plus two lots of cable to plug terminations)? This is usually the opposite aim to good quality cables.

    Seems like the answer - but not one i would expect.

    Anyone else got any supporting or other info?

    Cheers, Mark.

    For a while all Arcam and Linn amps came with the BFA outputs, which are what you are referring to, they are physically the opposite way around to the normal 4mm bananas.

    Ask the previous owner what amps he/she had. :)

    Is it possible to buy the crimp tool if you are not a dealer?

    It is if the dealer is willing to sell one to you, but the cost is not low.

    Thanks Retro,

    Yes you are right - they are BFA connectors (i'd heard of them, but didn't know they were a different design - had me really confused).

    Dave from QED replied to a query email and pointed out this link, posted here for anyone else who hasn't come across these before either:
    http://www.british-audio.org.uk/connectors.htm

    I'll just make sure my next upgrade path doesn't include any BFA connectors and then get out the snips (and buy some good insulated bannana's). I don't fancy paying another £20 and petrol for a dealer to replace the x2 BFA plugs with x4 Airloc plugs.

    Cheers, Mark.

    This really is an old thread, but I've been doing some homework on a new AV set-up for the not too distant future and came across this thread.

    What's so special about this Airloc crimper (€400, aparrently :eek:) or the actual workings of the crimp itself?

    I'd love to know if a normal crimping tool could achieve the same result?

    Surely these guys in hi-fi shops aren't wizards who are the only entities on the face of the planet who can operate a crimp?

    I am not convinced.

    looking at this qed page
    http://www.qed.co.uk/qed/airloc.php
    it shows a square crimp/compression design.

    But by its nature speaker cable is not square it is round, so with will have to be squashed into that shape and possibly leaving gaps, which in turn makes it only mildly better than the original style on the right.

    If you have a crimp tool/gun with the sight size jaws I'm sure that will work fine. :)

    vex, you will most definitely have less gaps and a much better surface area for conduction and also a far better contact in that surface area (than the alternative screw down connectors).

    Mark, I can't comment on whether a normal crimping tool will achieve the same result or not, as I've never tried it. The reason the crimping tool is only given to QED dealers is that we don't actually buy it. It is heavilly subsidised when we purchase QED Airloc plugs for the first time. I suspect if it was sold you would be looking at well over £150.

    The tool is of course specially designed for the Airloc plugs. Also, I suspect no dealers will sell you just the Airloc plugs without fitting them for you. You could of course ask, but when there is no extra charge for fitting them, why bother?

    I have attached an image of the tool.
