I seem to remember that Grado's load optimally into 10K ohm rather than the
phono preamp's standard of 47K ohm.  Mismatching the load would cause the peak
in the top octave.  But once loaded properly, the Grados perform reasonably
well.  Unfortunately, optimal loading requires some modification to the preamp
(~ $0.10 in parts at a surplus store).
