Possibly the same as a “double conversion” inverter, but with a grossly inflated price tag.

The filtered IEC inlets arrived today. So I took my extension block apart only to find that I could not fit the IEC inlet, as there is a metal shield running down the middle of the enclosure. So I put it back together, making sure all of the screws for the cables were tight. I then plugged everything back in, but in a different order (against the manufacturers recommendations). I also reorientated the mains block in an attempt to dress my cables. I have yet to hear the buzz tonight. I don’t want to tempt fate just yet…

Would an isolation transformer be a suitable device to cut down the noise?

I have a temporary fix, as what ever is causing the noise is not something I can turn off.
So my system is plugged in to the mains, with the exception of the phono stage. The system is now silent, but I want to get rid of the AG1500 power regenerator, as I know this is throwing noise back into the mains.

Can a ground loop be intermittent?
Every time I think I have fixed the issue after a few hours of silence, it comes back. It does sound a bit like a ground loop hum, that lasts for maybe one to two seconds.
