Is this normal?
They fully insert into my kudos titans

I had a set of superlumina speaker cables on demo a few months back, and this was normal.

Yes, this is normal.

Normal. And… you should pull the banana plug back 1mm. Yes, it makes a difference.

Very interesting. You would think the manual would mention this.
Naim really need to do better with their installation instructions or ensure their world wide dealer network actually do their damn jobs.
I might have missed this advice previously but may I know why and how. How do one know if 1mm. What happen if 2mm. I guess I more interested in the why reasoning.
Id not expect to see exposed conductors. Who would design for this? There is the potential, albeit small, for something to fall and short the amp.

Sorry, it should be 1.5mm 
The “plug-pull” tweak was taught to me by my friend who imported Naim into the USA. The theory is you don’t want the pin (speaker, DIN, etc) to be in contact with the end of the connector, thus being a conduit for vibration. I always pull speaker and DIN connectors back a millimeter(ish). I think it makes a difference along with proper cable dressing. Your mileage may vary.

Tks for the explanation on the vibration. I shall go try it.
I need to do that for both side right? SL cable to the 500DR plus SL cable to the speaker itself.
I do it on every connection: speaker, DIN, Power. Just pull them out a nudge.
I tried it with Burndy’s, but preferred the sound of them locked. DINs are always left unlocked, a well-known tweak.

For DIN I’ve heard it but never for speaker plugs.

All DC carying cables including DIN SNAICs are recommended to be fully locked by Naim.

Why??? whats the difference??? Is it a vibration thing???
I would assume the avoidance of possible damage by the power being unexpectedly disconnected is the reason for locking those cables.
Thanks to all I feel better knowing it’s normal
But why is it designed like this? Is it the same way on the Statement amps?
Or does it fully insert on these amps if they have a deeper plug receptor?
For such an expensive cable ( I have 7M) this does not seem right.
That said, the recent addition of the SL din interconnect + the SL speaker cable has been a fantastic upgrade from the HiLine and NACA5 cables.

Not sure why this is but it seems some sockets are not so deep as others.
As long as the fit is tight it’s ok but I feel your pain that it doesn’t look quite right.
I thought it was just that Kudos speakers might have shallow sockets as my Deltrons don’t go all the way in but do bottom out so I know they are in as far as possible.
I’ve often thought about putting little O rings on the plugs to fill out the space.
No problem on my Naim amp end though.

If you don’t know the connectors are hollow (they sound the best it seems), so aren’t very strong, especially at the 'speaker end, where they are prone to moving about/re-inserting etc,
I always now disconnect when moving the 'speakers any material distance, as the trailing SL cable is also quite heavy, so can tug a bit, which (IMHO) is best avoided.

I don’t think that’s entirely accurate. Even if the fit is tight, if the weight of the cable to the floor is sufficient enough over a long enough time, you can end up with a bend or even shorn Deltron (or any other similar long banana plug). As mentioned, I had it happen fairly recently and there are pics floating around on the forum of a shorn SL banana plug that nearly severed after a shallow bore socket on a standmount just couldn’t take the weight over the course of a year. A looser fit will just make it worse applying more contact pressure on a specific location speeding up the process. The angle of the sockets also plays a role. Though in my case it the terminals were a tight fit, close to the ground, with a cable not much heavier than A5 and over 3 years, the plugs bent anyway.
I have other speakers with the same problem supporting more weight of cable that have never bent the plugs. So I suspect it is not that easy to judge how much force your cable dressing is really applying to the pins.
If in doubt, one can always use depth callipers to measure the bore and then opt for either spades or another brand of plug (most are much shorter than Deltrons).
Hi
I was meaning that that the plug was fully inserted it wasn’t as if the plug was loose in the socket.
I do get what you mean about cable weight though and have experienced the shorn plug many years ago when it was the way for dealers to build up the plug buckets for bi wiring etc.
I’m using Kudos KS-1 it’s very light and is very close to the floor but yes I’d have liked angled plugs but not available other than using Naim pins but would mean a cosmetic fudge job.
When I remember having old K400 linn cable on bananas this is nothing like the strain.
I’ve even thought about applying some O rings on the pins to fill out the gap.
I raised this with Naim support when I first had my SL speaker cables and installed them with my 250 DR.
They acknowledged it to be correct but did not suggest Naim would ever do anything about it….
You’re quite correct in that a metallic object rolling or falling off the back of the amplifier could potentially short out the speaker output with serious damage.
I guess Naim’s view is, not seen it happen (often?) so be careful and thanks for all the cash
