Back in the day, before NAC A4 cable came out, Naim were great amplifiers and you just bought one and had fun, (or suffered abuse at the hands of the "straight wire with gain" brigade). And you learnt to solder those damn DIN line level plugs.
I have met Mr Vereker on several occasions and whilst I loved dining out at his expense, (thanks Julian I really enjoyed those times), the only view that I remember him expressing in regard to speaker cable, (back when 120's and 160's and the grand father 250 were extant), was that Monster cable was shite and a good figure 8 was all you needed. We had a Radiospares outlet in Perth and that's where you went for decent banana plugs and cable. I took a course in soldering. You learnt to dress cables properly. But that was it.
Latterly the science evolved and we learnt about power supplies, cables, stands... All great and worthwhile but it was mainly refining a great sound further.
Yes the balance of a system, (any decent system), is affected by "audiophile" cables. A long time ago you strayed at your peril from the carefully thought out synergy of a Linn/Naim system. But in my whole time as a dealer not one Naim amplifier ever blew up because of some strange, overpriced and over hyped speaker cable. The power amps are almost bullet proof. Yes the old ones run hot if you get it wrong and yes you can get caught in a hall of mirrors second guessing if it "sounds right' but bloody hell the worst that happened was they shut down. My admiration for Naim is based not only on their great sound but also, and almost as importantly, that the product is damn good, easy to live with and it very rarely breaks down.
We have learnt a lot over the years. Naim have demonstrated conclusively that you have to consider the minutiae very carefully. I believe in good cable, and the right cable. Positioning, dressing, directionality et al help make the system sing. But don't get too hung up on it all. Naim is not that fragile. And even when you've stuffed up they still sound pretty good.
