Van Alstine's idea is good, I would say. The rods will add lateral and torsional stability and the damping clarity. Problem is he's doing it to a Grado Prestige Green, a very cheap cartridge. I have a Blue, which is one step above. It is thin on the midrange and, being unshielded, will pick up hum from surrounding environment.
Keep in mind you can buy a $325 high output Ortofon MC from the Hong Kong market for about $120, though...
All in all, this hobby is about spending money!
