Following on from all of the above.
I had the follwing email conversation with Naim Support.
I note from the manual from my SN3 the following statement “however, a wide range of speaker cable types can
be used without risk of damage to the amplifier.”
Are there any type of loudspeaker cables that should definitely not be used with the SN3?
Thank you.
Kind Regards.

Hi
Sorry for the delay in responding.
Twisted cables add load to the amplifier, and can cause the amp to overheat, so we advise against using those. Parallel cables, with the red and black running side by side, are the best, like our NAC-A5 cable, found here: Naim Audio NAC A5 | Audio Speaker Cable
Kind regards,

Hi.
So that I can make an informed decision what is the maximum pF per M of the cable recommended for the modern Naim amps such as the SN3?
Thank you.
Kind Regards.
Roger.
Hi Roger,
That information isn’t available.
We advise on a minimum length of 3.5 meters per side, and of non-twisted cable for maximum performance.
Kind regards,
Duncan
Hi Duncan.
Due to space constraints and loudspeaker configuration, I need 2.5M and 1M jumpers. I do not have room to form 1M loops of NAC 5 cable and I cannot afford your more expensive cable.
I appreciate we live in litigious times and Naim only want to give out standard information and not to go off the script.
It is an unfortunate sign of the times that is the line companies are taking.
Oh, how I long for the days long gone, when companies were customer centric.
Kind regards
Roger
I’d like to think that we’re still of the older order, and very much focused on providing the customer with whatever it is that they ask.
I made some enquiries, and this is what I found, I hope it’s sufficient.
Nominal NAC A5 specification is:
9 mΩ
16 pF/m
0.9 uH/m
A supernait 3 should be OK with double that capacitance, but note that you should use the same lengths on both channels.
Kind regards,
Duncan
I then had the following email conversation with Audioquest.
Good Morning Alasdair.
Do Audioquest make any loudspeaker cables that can be used with a Naim Supernait 3 amp?
I understand that Naim amps will not tolerate high capacitance cables.
I “heard” a rumour on a forum that the Rocket 88 can be “retuned” to make it suitable for use with Naim amps. Is this correct?
Thank you.
Kind regards
Roger.
Hello Roger,
Alasdair is no longer working for AudioQuest, but we’d be happy to assist you. You are correct that Naim amps are particular with the type of speaker cable used with them. We can do a special Naim audio preparation on any of our Rocket series speaker cables that will work perfectly with Naim amps.

Hello Dustin.
Would the pF per M be less than 30pF per M?
Less than 30pF per M is the requirement of my modern Naim amp.
Thank you.
Kind regards
Roger
Hello Roger,
I checked with our senior director of engineering, he said the Naim preparation build ALWAYS works with both current and legacy Naim amplifiers. It has been tested repetitively.
Rocket 88 with Naim construction: 140pF / meter - 1.8uH / meter.

So I purchased a 2.5M stereo pair and 1M stereo pair and have been using them for two weeks and my SN3 is perfectly happy.
The Rocket 88 are, IMHO with my ears in my room, far better than my old WH Phantoms. The noise floor is at lot lower and all the “hash” has disappeared and the presentation is natural and neutral. The top end is clear and I can turn the volume up without wincing. The bottom end is tight and fast.
I am more happy then a happy thing.
