For me, the Benz cartridges occupy the middle ground between the fast, highly delineated sound of the uber moving coils favored by most audiophiles, and the rich, smooth textured sound offered by the Grados, Shure V15s, etc. In addition, the Benz cartridges from the wood bodies on up do something special with tonal balance that favors vocal, woodwind, and massed string reproduction in particular. Like the Grados, I find the Benz H2 to be a natural, rather than supernatural sounding cartridge. However, unlike the Grado Ref it is more rhythmically lithe, which shows up particularly well in bass and percussion heavy recordings.
Unfortunately, I can not comment on the suitability of either the Benz H2 or Grado Reference with your arm and table. That is what a trusted dealer is for.
