Who cares? It's not designed to run "flat." Just designed to run "flat" against the RIAA EQ plot. It doesn't matter how it sounds in ANY OTHER configuration.
Ever wanted to know, what your phono cartridge sounds like dead flat??
This new "GaN Technology" Class-D Integrated phono amp from Technics can equalize your cartridge flat for you using a test record that comes with it.
