Voici une réponse de Julian Verecker concernant la directivité des câbles ( provient du site

MY FRIEND TOLD ME THAT YOUR CABLES ARE DIRECTION SENSITIVE! THERE IS SO MANY VOODOO IN AUDIO MARKET, I ALWAYS THOUGHT THAT YOUR IMAGE IS RATHER RATIONAL THAN PARANORMAL!

Here follows a cut & paste from an earlier post of mine. "I can't tell you why cables sound different one way round to the other, but I do know when the 'directionality' happens in manufacture.
It doesn't seem to matter how the bundle (of copper) is drawn, single direction or mixed direction, but as soon as the insulation is extruded onto the bundle, the directionality is established. This means that one can mark the insulation and it will always be the right way round.
I suspect that the hot plastic insulation anneals the copper in some way, and this affects the crystaline structure.
But all our attempts, over many years, have failed to find any measurement to show the directionality or indeed whether one cable will sound better than another (other than the obvious - resistance, capacitance and inductance)
Maybe someone out there knows?"
I am not sure about being an ex Physicist, I would have thought 'Once a Physicist always a Physicist'. However one thing that is often missed by the 'profesionals' is that audio electronics design is the most difficult discipline of all - one has to design for 10 octaves and 130dB at the same time - a huge envelope, and much larger than any other area of electronics endeavor.

All Naim cables are directional, we don't know what the mechanism is, but they are all marked which way to connect them.

IT IS SAID THAT YOU RECOMMEND USING INTERCONECTS MANUFACTURED BY
CHORD.

To set the record straight, Naim (the manufacturer) does not recommend other manufacturer's interconnects - Chord or anybody else. . . One of the reasons for this is that although a cable from a particular batch maybe suitable, mostly the variations in other's products do not make them recommendable.
Its one of the most variable supplies we have and one of the most difficult to maintain consistancy.
