If the Coph Nia has a three-prong A/C cord, try using a "cheater plug" to lift the ground connection. Also, is the turntable well away from power amps or other large transformers, ie power conditioners? Hopefully, the phono cables are shielded, but even so, keep them away from power cords. Good Luck.
Hum causes: MC cart, arm cables or phono stage ??
Dear ALL, I have a Denon D 103, Sme 309 and its cables, plugged to a brand new Phono stage from Coph Nia.
I have a consistent hum that I was not listening with my previous system (Grado cart+ Rotel phono stage).
It does not harm when listening to medium level rock music but I think it will be listenable when playing low level piano music for instance.
Shall I investigate and how in all the rest or the pre stage can have its part of responsibility ??
My feeling says that this MC cart is quite sensitive and probably the previous one (MM) was not at all.
I would like to know if the hum is due to the pre so I can try to give it back as it is new.
How can I check if it is part of the problem ??
Tks so much
