I picked up a minty P25 for my office system and it is plagued by a grounding hum when picking up the arm - which keeps going after putting on the record. I know Rega uses an odd left channel grounding setup. I took it back to the place I got it and they replace the Nagaoka MP-20 (which I loved) with my Ortofon 2m Bronze, based on their experience of Nagaokas sometimes having grounding issues. While the buzz is reduced, it’s still there.
I previously had a similar problem in another part of the house with my LP12 which was resolved with an arm rewire.
I suspect I may have an elusive grounding issue in the house overall, however, my LP12 is now ok so the lazy part of me wonders if there’s a good TT solution.
Any thoughts? I do like this P25, it’s miles better than the 90s Planar 2 it replaced (though no LP12).
Oh and I should add - the TT is dead quiet at the hifi shop I bought it from.
