Description
The NAC A5 is a speaker cable from Naim Audio, designed to connect an amplifier to its speakers. In a hi-fi system, this type of link plays a role in its own right: it carries the power signal from the amplifier to the speakers, and its electrical characteristics directly influence the way the system reproduces sound.
The NAC A5 is made up of two separate conductors, each with a cross-section of 4 mm². This multi-strand design was developed to offer capacitance, inductance and resistance values consistent with the requirements of Naim amplifiers, ensuring electrical compatibility between the electronics and the cabling.
Although designed primarily to be paired with the brand's amplifiers, the NAC A5 remains usable with any type of speaker, making it a cable adaptable to different listening setups.
This cable is intended for owners of a Naim amplifier wishing to complete their system with a speaker link consistent with the brand's electronics, following a logic of a cohesive system rather than a simple generic accessory.

What to check before buying used
With this type of link, what matters most is at the ends: the bare conductors oxidise over time and the original crimps or spade connectors can come loose, which degrades contact with the amplifier and speaker terminals. The sheath deserves careful inspection along its entire length, checking for cuts, pinching or crushing marks that could reveal routing under furniture or skirting boards. A continuity test or a listening test on both channels rules out any risk of a broken strand invisible to the naked eye.
