@winoguy17 , that's a good thought. My SS amp has high gain and was boosting the noise level previously on a shared dedicated line. Since I moved my system to a subpanel with a line dedicated to analogue, the noise floor has been greatly reduced.
As a test, I hooked up an old Kenwood amp with much lower power and the noise from the mains was still present.
@yakbob , I tried a Jensen transformer between preamp and amp, but I have an Atma-Sphere OTL pre and the transformer ruined the sonics. I've seen some comments by Ralph(atmasphere) where he says putting a transformer inline with an OTL device can have unpredictable or negative results.
@lak , I like the concept of the iso transformers and looked at how you've implemented them. That type of setup would work in my basement, but cost is a consideration. I will ask my electrician about it and show him your pics, thanks.
