Is 3 meters of SL long enough for use with a Nait 2 or chrome bumper 250?
Asking because that length is available at a good price, but I know Naim recommend a minimum of 3.5 meters of NAC A5.
Deep pull from the archives! Thank you

Does Super Lumina meet the spec. though ?
These earlier figures related to NACA4/5 didn’t they ?
Not bothered.
Everyone told me to use KS1 as it matched perfectly with Naim
So that’ll do for me.
Most of it is sales guff anyway.
Can’t imagine Naim manufacturing “ or branding “ something not suitable.

But, the quotation you posted may not be relevant for a cable made 40 years later to a totally different spec.
When the poster is talking about Super Lumina, then we need to know what is an acceptable length for THAT cable.
Otherwise, who knows what may happen.
It’s the length of the cable that is in question.
If Naim have a cable made that constantly gets quoted between 3 and 3.5 and the amp gets damaged for the sake of 500mm of same spec cable then I don’t reckon the amp is up to much.
Metres make pounds the longer the better 
I certainly don’t think they will later brand a boutique cable not suitable for their own equipment.
Naim website blurb suggests that any length can be used as they custom assemble with no limitations.
“ Every Super Lumina cable is assembled by hand at Naim Audio in Salisbury as per the customer’s specifications regarding length and termination.
The assembly process is intricate and highly-skilled, following detailed instructions that cover every aspect of the build. Additionally, every cable goes through a proprietary de-stressing process that relieves the materials of the inherent stresses resulting from the manufacturing process. This ensures that the cables reach optimal performance with minimal run-in time.”
I think if if my system would fail for 500mm of cable we all need de-stressing. 
The earlier olive amps needed 3.5m of naca5, but the capacitance/inductance of superlumina is a little different.
NACA5 inductance = 1uH/m
& capacitance = 16pF/m
Superlumina moderate inductance 0.74µH/m
low capacitance 66.4pF/m
Just in inductance, you would need 3.5uH so that implies approx 4.5m of SL.
But then the capacitance of SL vs naca5 is 4 times as much.
Then again some people use 10m of naca5 without issue.
Yes. It will be absolutely fine.

That’s what I tried to say too. 
Sorry, but we are talking about the length of the cable, not the suitability.
Quoting ‘Julian’ from 40 years ago is not relevant to a different cable made relatively recently, that bears no resemblance to the cable Julian was referring to. And suggesting such is negligent.
Many cables are suitable for Naim gear, but they are suitable at differing lengths, depending on their specification.
I’m afraid it isn’t that ‘one size fits all…’
Indeed, Super Lumina in 3 metre lengths may be suitable, but it has nothing to do with Julian’s/Naim quote you posted.
There’s nothing catastrophic that happens when you use a cable slightly shorter than a particular length. It’s just a guideline, so perhaps it’s not surprising that a forum post differs slightly from Naim’s formal recommendation.
There are minimum figures, not optimum figures. If you want the best performance from your power amp you should be looking at 5 metres or more.
For virtually all cables other than NACA5 and NACA4 the minimum will be more than these figures as the capacitance will usually be higher and the inductance lower.
Exactly.
I think this goes together.
What a whole load of guff about nothing.
As I said if 500mm of cable makes something not work then the amplifier design is more questionable than anything.
Standard conversation on forum dictates that all cables are mentioned in the “ recommended “ lengths.
I’m sure it’s not quite so critical but merely a guide.
Life is too short never mind the cables.
