Low humming sound through speaker

Continuing the discussion from Naim nap140:
I have the same problem again but only one channel. What could be the problem
Setup NAIM NAC32.5/NAP140, KEF C80 speakers, NAD CD player, MSB Link DAC3

If this is an early sign of problems in your power amp, the worst case scenario is that it will eventually fail and quite possibly destroy drivers in your speaker, which can be a more expensive fix than the amp. Get it serviced before it’s too late.

Your short speaker leads could be a factor, does the amp get hot, or did it before it started humming?
