8TC jumpers

If you have bi-wiriable speakers, there’s a chance you might not be hearing the full performance they are capable of. Russ isn’t a big fan of biwiring per se; he feels that some amplifiers find the load of two sets of speaker cables difficult to handle, with the result that although some areas, such as bass, sounds better, while others – such as the soundstage and the musicality – are worse.

Another problem with biwiring is that you need to use two runs of cable – or a properly designed biwirable cable. This can double the cost of the connection; we feel it’s much better to spend that money on a better quality single run of cable, rather than two runs of a cheaper cable. Most speakers provide ‘links’ to connect the two sets of binding posts when you are single wiring biwirable loudspeakers; these links can sound terrible and may well be the reason some people report improvements in sound quality when they biwire – simply because they’ve removed them!

If you are single wiring, we provide jumper cables that enable you to replace the links with high quality Kimber cable. The difference in sound quality can be stunning and you can use them even if you don’t use Kimber’s cable as your main speaker cable (though we think it’s much better quality if you do!)


The back of a typical biwire speaker. The bottom set of binding posts handle the bass and midrange; the top set handle the higher frequencies. Note the ‘links’ connecting the binding posts together.






If you want to single wire your speakers and use our jumper cables, first remove the links.






Our jumper cables are supplied in sets of four (enough for a pair of speakers). Fitting them depends on the type of connections your speakers can accept. Having inspected them, we find that these speakers can accept bare wire, bananas or spades.






Since our main speaker cable is fitted with bananas, we’ve opted for jumper cables that are fitted with spades and bananas. First, we connect the spades to the bottom set of binding posts – this is where the main speaker cable will fit when we wire the system later. Using spades means that the socket for the bananas are free.






The other end of the jumper cables connect to the top set of binding posts. Make sure the red post connects to the red post and the black post to the black post. Simply plug the banana into the top set.






All you need to do now is to connect your main speaker cable to the bottom set (the low frequency) binding posts. Simply sit back and enjoy your music!
