Ground isolating transformers these days will be usually 10k in and
out.

Wow, now that's got me confused!

I am not using old tube equipment and I'm not using pro stuff either.
Instead of 600-600 ohm, you seem to be saying that I need 10K-10K ohm.

Can you or someone else explain this a little please.

10K-10K seems very different from the 600-600 which I was about to get!

Well, what exactly is it you're trying to accomplish? Your original post
was quite vague, and seems to have been lost in a sea of speculation -

What are you trying to connect to what?

And if you have a ground loop, the solution is to diagnose and repair
the loop itself, rather than apply band-aids.

What do you have now, and what are you trying to do?

Thanks,
