It also acts as a high pass filter for RFI. which is beneficial.

LOL half my post disappeared for some reason, Alan has covered it. I was planning on fitting an earth point on the pre so I could wire cable ground to that via a resistor. A wire can then be taken back to the chassis of the other component.
Whilst looking around last night I came upon these so am getting some to try-

Hopefully that will do the job.
Something like this would provide greater connection flexibility - all flavours at once :)

Yeah looked at those on Thomann, have enough on the racks as it is lol.
Just a quick thank you.
I had a hum and after reading the comments on this post plugged my pre and power in to my plug board with all my source components instead of in to the wall. Hey presto hum gone or at least insignificant.
It's magic!
Good result. :-)
You'll be waiting a hell of a long time for an evaluation from me.
I DON'T have any ground loop issues.
I have on occasion had fun solving ground loop issues on paging amplifiers in offices and the like.
The box shown is just a couple of isolation transformers with paralleled inputs and outputs http://artproaudio.com/product/dti-d...rmer-isolator/
As I explained elsewhere, an isolating transformer will not necessarily solve a hum problem. Hum is an AC signal of 50Hz (plus harmonics), so will be passed through a transformer. I once had a mild hum problem with some AV gear. I tried a 1:1 transformer - it didn't work. What did work was me tracing an earth loop and breaking it.
