The Primare is young (about three months) and it has played more than 200 hours. I never switch my gear off, they are constantly on. There is no hum from the Primare at "normal" output levels, only when I turn the volume pot to maximum level. In that case the hum from phono is considerably higher than from CD (of course no signal in either case).
It is normal for hum and noise from an MC phono input to be much
higher than that from a CD input, at normal volume settings though
the hum and noise should be inaudible.
Completely disconnect the turntable and set volume to maximum.
This gives your reference level, reconnecting the turntable should
not make the hum it noticably worse, if it does sort out the earthing.
