Naim Audio Servicing
Having been Naim Audio users for the last 25 years, we understand the need to occasionally service Hi-Fi components to keep them sounding their best.
Outside of normal wear and tear, they are not immune to faults. The good news is that there are options which are designed and fitted by our in-house service engineer.
As always, it is dependent on the exact component and fault as some parts are simply no longer made, with no alternatives available but contact us first so we can diagnose and advise you correctly. See below for the upgrades menu.



Naim Audio Upgrades
We are seeing increasing numbers of component failures in many Olive and Black series Naim components. CD players are particularly prone to various failures and given the level of investment made into these players and lack of available parts, it makes sense to look at upgrades to continue your enjoyment and in many cases, enhance it.
Here is a brief menu of the upgrades available. Given the range and complexity of components available, contact us for anything you don’t see listed. All upgrades are performed on fully functioning components and any necessary repairs will be charged separately.

DAC Replacement - £400
This is a common failure mode on the CDX where you will lose one channel. Our premium DAC module is custom fitted inside your player and by optimising existing power supplies, gives the same effect as using an expensive external DAC while keeping everything fully optimised and in one box.
