We don't have to worry about the Marantz amp, as all the 6000 series are double insulated and have a two pin mains connector. The Primare R32 has a three pin connector, so its metalwork is earthed. It also has a ground terminal which is directly attached to the metalwork.

I can't find much information about the Profiler arm and how the metal work is earthed/grounded. Does it have captive signal leads, and is there a separate ground wire?

So depending on how the tone arm leads are connected to the R32, including the separate earth wire, it is quite possible to create an earth loop.
Tone arm leads are straight into the phono inputs of the Primare and the Earth wire also goes straight into the Primare.

Does this mean the I could disconnect the earth from the Primare?
