Does NDS needs service?

I predict in 2030 we will have similar bad news from Naim about the Nd555.
I strongly hope not.

As this is a discussion forum which Naim host we know that they don’t use it to give formal information. Have you tried emailing Naim support with this question? If you get a definitive response ask if you can share it with the forum. That would be very helpful…

I will probably ask about nd555

I was under the impression that NDS’s don’t need serving be good to get confirmation as mine is getting on a bit!

The nDAC certainly used to be serviceable, we had ours done in 2022.

They replaced some capacitors according to the service sheet.

I remember that some, who bought the Ndac in the recent years , sent it for service. Some said the sound didn’t changed, other found an improvement.
It was never clear if the Ndac needs or doesn’t need a service.
The same now concerns the Nds, and very probably the Nd555.
If only Naim could post something official on it. But I doubt they will.

FR, I think best wait for Naim to do their review.

My NDS screen has gone very dim.

I’m planning to return it for a repair under dealer warranty.

Is it now impossible to get Naim to service it/check it and change any capacitors/tants at the same time?

AFAIK Naim can do repairs on the NDS but otherwise you should check with your dealer/Naim service on what gets done.

Good question. I am very interested too. My Nds screen was not working. So, like you, I would like to know if i send it to Naim, will they repair only the screen or can they change the capacitors also.
Let us know what they will respond to you.

Will do, FR.

And vice versa.

I returned mine for a new screen this Spring. I was advised they don’t do a service unless there are issues ie a repair. The screen was very reasonable, but it did have to go back because they damaged the remote sensor which is adjacent…

Without a power supply in the NDS, I’m not convinced that there is likely to be any merit in changing capacitors in the relatively short term, which encompasses the age of even the earliest production NDSs. Somewhere I read thar the NDS uses a lot of tantalum capacitors. Whilst I seem to recall that early tantalum capacitors sometimes had a limited lifespan, my understanding is that modern tantalums – say at least by the 1980s – are recognised to be stable and reliable devices, and are likely to still be within spec after 20 or 30 years or more. Of course there can be exceptions with a capacitor failing, just as there can be with any component, and that could happen at any time from day one onwards, But that would come under repair not servicing.

Tants get changed at the regular 10 to 15 years in Olive and classic power supplies.

I’ve bought a spare screen on the bay for my NDS in case things change in the future.

@Richard.Dane response: „ Looks like there are Tants but no reservoir caps - they’re all in the PS. The big reservoir caps are the ones that will most likely need a scheduled change.„
