As Clay said above, based on a modified Nagaoka MP150, it is a very good MM cartridge. Goes great on a Simplex, and I have also heard one on a Consonance Wax Engine table as well, another great match for reasonable price.
Another cartridge at similar pricing-$530 US, I am curious about is the LP Gear Vessel R3SV MM with Ruby cantilever. I think the TLC is $550 US.
PS-I would say that a Dynavector 10X5 is another good match on the Simplex, nice high output MC.
