Hi Guys
In My experience Naim amplifiers are much less sensitive to cable than some would have you believe. I own a Bolt together NAP160, NAP140 and a NAP250. I have used various cables including a cut up 240V 10amp extension lead, a generic 14 AWG flat cable (two flat conductors positioned side by side), and my preferred cable, based on cost and availability, is a generic 12 AWG two parallel cores available at my local electronics hobby shop. I am yet to experience any sign of instability.
The main thing, as mentioned in the manual shown above, is not to use “SO CALLED HIGH-DEFINITION WIRE…”. Most of these geometrically complex, braided or litz style cables are not much better than wiring a capacitor across the amplifiers output, I tend to avoid this type of cable for any amplifier.
Oh; and the 3.5 min cable length; It is a rough guide only, the manual says “should” not “must”, two very different words. I have use lengths as short as 2 metres with no problems. Just avoid the platted / braided type cable and you will be fine.
