My Superline is now at my dealer who couldn’t replicate the issue. They are going to partner with Naim to understand more.
Quick question @Richard.Dane . I’ve just realised there’s a ground connector on the 252 which I wasn’t using. Should I have used this instead of the one on the back of Superline when powering from Supercap?
Not sure what the best practice is
Cheers

The Ground connector on the Superline would be the one I would use, although its sometimes worth experimenting with different ground connections where you have hum issues.
Did your dealer have all of the kit from you - the Superline and the same Supercap and Burndy? It’s the combination of all three items that, if all are at one end of a particular tolerance, can sometimes tip into instability.
Thanks - gave them the Burndy but not supercap as I tried 2 at home
Update
Just got the Superline back from Naim who have installed a mod under warranty and sorted the hum issue.
I don’t have any hair left to pull out so will just warm everything back up and enjoy the music.
Thanks to everyone who’s contributed to the thread and my local dealer (Hi-Fi Sound in Stockton-upon-Tees) for their support, patience and resilience . Appreciate it.
Cheers
After re-installing after the modification, the sound wasn’t great. Wondered if the mod had an adverse impact.
After 5 days everything is sounding great again. Thank goodness. Weird why things take a few days to settle in from cold
Did they tell you what the “mod” was? Is it unique to the 2018 SL or does it affect earlier SLs also?
It’s likely the same one that has to be applied when the tolerances of Superline, Burndy and Supercap all add up to be just “off”. It’s rare but has happened in the past, as perviously documented on the forum.
