Naim amplifiers do not have inductors in the output, we prefer to use the speaker cable to provide the correct inductance and capacitance.

To do so a minimum of 3.5 metres of cable is required – although the optimum is around 5 metres. We find the supplied Naim speaker plugs to be an optimal match for the 4mm sockets we use on our amplifiers.

In addition, the plugs are designed in such a way as to prevent them being accidentally inserted into European mains sockets - hence the warning in your Owner's Manual
"The Naim loudspeaker connectors supplied are designed to comply with European safety legislation and must be used."

Cable length for left and right channel should be of exactly equal length – even if one speaker is closer (as is often the case) to the power amplifier.

Spare speaker cable should not be coiled – excess cable may be tidied up in a way similar to that employed in the “Jumping Jack” firework illustration below.

Use cable ties or similar at either end to hold in place.

Additional: I would not recommend any particular length for the folds - you can make the folds suitable for hiding but use some sense. You are most likely to end up with one cable needing to be tidied - that to the nearest speaker - giving the distance between the speakers as the amount to be dealt with.

Avoid having the doubled (tripled or whatever) too close to either the speaker or the amplifier end of the cable - to give as much flexibility as NACA5 allows for the final run at each end.

Avoid running the cables parallel to mains cables.
