Sancho, there is a gold knob on your preamp that is specifically for the TT ground wire. That being said, I have moved my A23 SUT, and all of a sudden, HUM! Then I just play with location, massage the cables a bit, and NO HUM! Try just moving a couple of inches here and there, IF the ground doesn't do the trick. Let us know !

Hi,
Try a grounding loop.
Connect both the ground cable of the TT and the ground cable of the SUT to the ground plug of the preamp.

I mean try a "star grounding". Not a grounding loop ! Sorry !

That's right. Ground both to the pre-amp.

I have a 103 Expert Stylus Co.
Pretty different from the EMT TSD15.
I would say that the TSD15 is more balanced while the 103 puts a lot of bloom and emphasis on the mids.
I prefer the EMT also.

Thanks guys for the suggestions - will try and report back!

some improvement but other cables still too close…need to experiment further

Hum is still very strong despite placing the SUT on a separate shelf by itself alone.
I don't have enough Shindo IC yet so I am using Stealth IC and the Kuzma TTs original cable. Will try some other cable but trying to minimize it due to the sensitive shin do connections on the pre.

"I am using Stealth IC"

And that is the problem.

Yup. They work wonderfully with other gear. I pulled up some decent MIT i had on hand.
Major improvement - still not perfect but almost - much better fit physically. I will do my best to get Shindo IC but i need to await my bonus in March...
