Yes, cable directionality is established by the spinning of the RS hook-up wire reels as multiples of $24/ft lengths are being pulled off.I see these are directional, too...
Regardless, my offer stands to run the specs of any alternative cables that Naim owners wish to consider. As @Gervais Cote found, the difference could be down to one's amp running circa 8ºC more than is typical. Those alternative cable users that prefer to run their's 24/7 should really consider having a closer look.
Hi Joe,Craig, I'd be delighted to take you up on your offer! I got tired of wrestling with/looking at my incumbent NAC A5, so I bought (secondhand, here on PFM) some Vertere "Pulse X Mini" 5M speaker cables. I had heard a rumor that Vertere makes the SuperLumina cables for Naim, and since my 250.2 is more tolerant of different cables than the older amps, I took a punt. The 250.2 runs as cool "as the other side of the pillow" with the Vertere cables, so I figure they can't be too far wrong. I tried to find the specs of this cable, but couldn't find any.
You're welcome @joe9407. Does the Vertere box have a slide switch on the side?
I use relatively generic 4mm 99.99% OFC copper cables which happen to be 2.5m long because I bought a 5m spool and cut it in half. Works great with the Nait1, the NAP140 and I assume anything else.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.

Are you saying that that most manufacturers don't include a veil with their audio components?If I had 10p for every time...
I have a BD Nap 160 with the Zobel removed,it sounds much cleaner and better without it.The zobel if anything is the more important bit as I understand it - it means at HF the amp 'sees' a resistive load. Good for stability. The Thiele network 'stands-off' parasitic capacitances (and RF) from the amp at HF, and so adds to stability from load interaction effects. Ironically, while you see amps often tested with a load of '8ohms in parallel with 2uF' for testing, it is smaller capacitances, tens of nF, that can really destabilise power amplifiers and provoke a riot above the audioband /meltdown resulting. The late Cyril Bateman published some analysis ('Cables, Amplifiers and Speaker interactions') using a DSelf 'Blameless' amp - and cooked the output stage once or twice in the process IIRC...

But it sounds so much better,as long as you do not shorten the speaker wires.DO NOT UNDER ANY CIRCUMSTANCES DO THIS!

I have also had a Nap 110 with this mod with similar gains in sound quality.
Okay I see,thank you ! I will have the Nap 160 serviced back to original.Naim NACP (Naim Audio Crock Pot) conversion, 'World Class Slow Cooking', 24/7...
