Phono Stage Hum

One more update:

-I ran the turntable directly into the phono stage of my Creek 5350 SE. No hum.

-I then ran the turntable into the JD 9A and the JD 9A to the Creek. Hum.

It seems to me that it is clearly something in the phono preamp. Right? or in the connections/settings.

Off to play around with the placement and settings on the 9A.

The phono pre-amp seems to be the suffering piece.

Hopefully it is just external magnetic fields that can be taken out of the equation (like kryptonite with SUperman) rather than some inherent problem with the piece itself.

Good luck.

I think it might be something external. I have slowly dismantled and reassembled my system. I also reset the impedance on the phono preamp. I have reduced the noise/hum significantly but just discovered that at very high volume levels (with nothing playing) that it is picking up radio signals!?!?! It does not happen when I run my turntable directly into my Creek. It does happen over either amp when I introduce the Jolida phono preamp.

Right now, I have the gain set to the factory recommend and I'm running out on the "low" line out. The sound is great, and I never really get to the 50% point on that amp with the Druids, but it seems like there *should* be someway to clean up that noise.

I did recently read a review on 6moons of a device that is supposed to clean up external fields (if I remember correctly).

See this recent thread for some ideas about what to try with respect to the radio signals:

It might be those Zu Xaus cables. Are they shielded?
