Shameless lurker here with an ND5XS2 less than 1 year old. Has been functioning normally until 10 days ago when suddenly I am gratified with an enormously LOUD transformer hum which is ruining the listening experience at 3 meters away. Have done this:
- Read the various threads here on this topic and remedies.
- Have changed power cables, interconnects, plugged unit on different sockets around the house, checked for new devices plugged in elsewhere, looked for faulty SMPS or LEDs in the house, etc…to no avail.
- Contacted dealer who basically said this is not Naim’s fault but mine…at my house.
My simple question is: has anyone experienced this turning into a service requirement with repair and resolution by Naim?
As it stands, I am fully inclined to sell this like-new unit which is producing more hum than music (in the case someone would actually buy it).
Incidentally, I find it somewhat perplexing that Naim is getting away with producing boxes that hum as a matter of principle and that users are accepting this. Normally, as audiophiles, we are on a constant witch hunt to identify sources of unwanted noise and to eliminate them.
So, yes, quite frustrated and unhappy with this product. SN2 is not humming and nothing else in the house is humming either. Both are plugged into dedicated mains installed by certified electrician for use with hifi only.
Any comments/direction would be appreciated.
