The Mu-so can be serviced and repaired - by us in UK and Naim service centres around the world. As even the oldest, original Mu-so is only 7 years old, I don’t think the subject has arisen yet re in-life service - I will enquire!
I believe Naim have changed their stance on this. Perhaps recent legislation on sustainability and repair of electrical equipment influenced them here.
Our larger distributors have their own service centres, fully trained and stocked by the teams here in Salisbury. It varies from country to country, but as we continue to expand globally, it’s a vital development.
I heard back on this. There should be no need for a service in the traditional Naim sense. But, as noted, repair options are available should you encounter any issues.
