Agree Murmur, the directional thing isn’t Linn and Naim exclusive, but also happens to cheap speaker cables from Mogami and Canare widely adapted by music studios – try yourself and find out.
A good piece from old forum and Julian sounded making sense, also align to Richard’s story of Roy once returned a full drum of Naca5

your memory is good.

Subject: directionHere 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.
