Hi Many thanks for letting me join this forum
I have a question about Naim speaker cable. I have two lengths and I wondered if it is the NACA 4 or NACA 5. It is white very stiff and inflexible. It has Naim Audio repeated down one of the two strand sections. I can post pictures if that is allowed
Stiff and inflexible tends to suggest it is NACA 5. A photo should be able to confirm it.
Definitely allowed and would be helpful probably 
A5…
It’s definitely A5. I’m not sure A4 even came in white.
I am finally released from the curse of the Naim forum. I know something @HungryHalibut didn’t know. I’ve got some white A4 in the garage.
So long and thanks for all the fish…
White NACA4 here also…
Well there we go, white A4. Anyway, the OP’s is A5.
I have some old NACA4 somewhere - it was probably once white, but last time I looked it was now more like a creamy beige…
I have White NAC A4… 
I even have a price list with White & Black listed…
And… thats what my A4 leads cost me. £1-00 per metre… 
Thanks for rubbing my nose in it! I have white cable, but it’s Kudos KS-1. No hairdryer required.
And the carpet from hell.
I’ve seen far worse much more recently.
It was 35 years ago and the only photo I have.
I could show you some really scary curtains if that’s your thing. 
Anyway about that speaker cable. 
Thanks for all the replies.
Here are a couple of photos
And another
That’s defo A5.
I agree🙂
I’d say that would probably have been Linn LK20.
On reflection your probably right it was got from a dealer long gone now but it was identical to the black cable running the external crossovers on the back.
