help please. i need opinions of high output carts

i've just switched from a rogue 99 to a marantz model 7 preamp. love the marantz, but my low-output grado statement (4.5 mv on mine) needs replacing with higher output. table is a vpi aries (which i also love); amp is david berning designed audionics of oregon ba150; speakers good old kef 105.2's although i switch to bozak rhapsodies when i need to move more air. any suggestions? i've been recommended a benz micro h2, a van der hul mc2, and a dynavector 20xh. sounds to me like the 1st 2 may be in a higher league but i have no way to really know. HELP!
