Is analog supposed to be so noisy?

Sounds like a ground issue.

BUT

In my experience having an appliance running at the same time I'm enjoying analog, causes some hum. I live in an apartment, and whenever the fridge kicks on, or the washer/dryer is running, I'll notice some hum that is more apparent in my analog path more than digital.

This all depends on the wiring of your house of course.

Try moving your interconnects from the TT to the pre-amp and see if the hum changes. Often just passing the IC's anywhere near a power supply (including PC's) will produce a hum. Phono IC's can be a real problem sometimes!

Oh, have you located your TT near any components with power supplies, like amps? Give it lots of space from other stuff.

I'm not familar with the Luxman, but I had a TT some time ago which terminated the arm into a small box on the back of the TT and then you used your own IC's from the TT box to the pre-amp. Never wqorked w/out a hum! I replaced the box with a Cardas phono cable with a DIN plug that connected directly to the arms base and never had another problem with hum unless it was from a nearby power supply. The Cardas was not well shielded I think.

Hope this helps a bit.

My Luxman turntables have a little delicate ending to the ground wire. Consider double checking whether this wire end is actually making proper contact with the grounding post on your preamp.

Thanks, guys, for all your responses. Indeed, the ground wire was broken; I spliced it and 95% of the noise is gone. Certainly not as quiet as digital, which is practically noise-free, but quite an improvement!
