This post is worth a read IMO.
If Naim and your dealer have diagnosed correctly, then they likely saved you the cost and or hassle of sending your player back to HQ. If they expect they can fix a thing, they will, but don’t give false hope if they genuinely cannot.
I have to say I think Naim actually do go above and beyond, compared to much of the competition. That’s still the main reason I plan to stay with Naim for any upgrades.
I wish you the very best of luck resolving the issue with your player, or finding a suitable alternative, Naim or otherwise. Personally I think it’s difficult to find many equivalent manufacturers when it comes to long term supportability
