If you do go Grado, to match the preamp, use one of the lower outputs if you can adjust your gain. The Statement Series is around .4mv and there is a VPI run out there at 1.5mv( I own a VPI Sonata). they are suppose to sound better b/c of the smaller coils(less wire). Haven't heard Shelter so I can't compare. Or you could get a step-up to play those lower ohm MC's.
