I have seen a couple of posts on this subject already but nothing definitive except maybe have to send it back for service:
The right channel on my SN3 just went out after being turned off while I was away for several days. I bought this unit new slightly over a year ago.
I have tried all remedies:
Complete shut down.
Reseated all interconnects.
Swapped speakers
It happens across multiple sources.
I had a Hicap DR powering it but removed that ps and reinstalled the link plugs.
No change at all.
I just contacted the service dept at my dealer. Waiting on reply. Just thought I would ask the experts here too.
yep I’d reckon it’s the relay, Naim are obviously still using these duff components unfortunately knowing they’re prone to failure. Anyway it’ll get sorted under warranty.
