What happens if you don’t do this, is the buzz still gone or back?

I do not know, I do the test tomorrow, now 12 hours after the power on continues to be very quiet
Maybe should open my humming 250DR and see If the bolt is loose. Thanks for the tip.

My lawn mower makes noise during operation. Does this detract from its functionality? No, of course not.
My Naim gently hums, does this affect its functionality? Not to me it doesn’t - I just choose not to attentively and obsessively listen for it.
Unless Naim specifically detail that their equipment is silent in operation - and the hum doesn’t become audible during playback - I don’t see what the issue is…

It really depends on the volume level of the hum. Certainly where music is playing, I doubt anyone can hear the hum. But the thing is, these systems are in our living rooms where many will spend a lot of the time not listening to music, and therefore if the level of Hum is high, it can be very distracting and annoying. Hence why there is so much chatter on this Forum about it.
My CD555PSU hums along merrily so much so I had prospective buyer pull out of my sale due to the
noise.
A (Naim accredited) Tech informed me all Naim toroids hum to some degree-he had no fix.
Guess just gotta live with it.

Hum from my Nait 5i 2 easily fixed with dedicated power supply.
Why don’t Japanese toroidal power supplys hum?
I was mulling this over whilst mowing our front lawn at the weekend.
I concluded that whilst our petrol cylinder mower did cut the grass well, a quieter mower that produced little or no emissions at the point of use would make the experience much pleasanter.
