The paper work that came with cartridge has a performance graph and showed the units performance when tested at factory.I see in your thread from a few months ago that you are using the Clearaudio Concerto V2, a low output moving coil cartridge, not the much higher output moving magnet Virtuoso V2 cartridge used by the OP. Although you reported also experiencing excessive brightness. What did the performance graph you referred to show?
