Are Tellurium Q cables directional?

Tellurium Q® speaker cables do not start out directional but we have noticed that they tend to exhibit "directionality" once burnt in. This is especially true for the higher level cables so we have arrows on these cables indicating direction. You should set up your system so that the arrows always point away from the source, i.e. DAC, Turntable, CD player etc through the amplifier towards the speakers or headphones.


The way in which we bi-wire is not a case of dividing up a single cable to separate the signal. We use a whole extra cable and fix it at the amp end into the one connector so you really do get an appreciable audible gain in performance. The cables are then kept separate all the way to their respective terminals. The downside is that it costs almost twice as much as a single with jumper but the upside is that the performance is exceptional. Depending on which cable you choose it is often better to go up the range instead of bi-wire. For example a single wire Ultra Black with a jumper will way out perform a bi wire Black speaker cable. If you are already looking at the top of the range then bi-wire and sit back.
