Cartridges and phono settings

[Eddye]

It looks like many of us are setting the max level setting in the Devialet very slightly over the cartridge manufactures stated output (which seems sensible), and we all are getting readings in the -40 to -20dB range, and in some cases lower (which seems rather odd).

Does anyone have a clue why this might be?

Haven't adjusted the load in the config yet, my reading is between -60 to -40.
