Is there any difference in the cartridge body/generator in the Grado Prestige line?
According to the rather vague Grado website, it seems that the stylus/cantilever improves as you go up the line. The black/green has a three-piece cantilever with a "specific diamond." Then the blue/red has a four-piece cantilever (more pieces is better?) with, I assume, the same "specific diamond." Lastly, the silver/gold has the (same?) four-piece cantilever with a "specific elliptical diamond." Does this mean the black through the red have a lower-quality diamond? As for the rest of the cartridge, however, I can't figure out if it's the same or different from black through red.
EDIT: I see now that in the silver/gold a "machined turned generator is used to achieve a lower distortion and greater transparency." It looks like the black through red don't have this.
I'm not really hung up on technical details, but I do want to know what exactly you get as you pay more to move up the line, and how much of a difference that really makes in the sound quality. I respect that the gold is significantly better than the rest of the line, but how much of a difference is there, say, between the black and the blue?
Would I be wise to start with a black to try out the "Grado sound"? Then later, if I like it, I could upgrade to a gold cartridge or an 8mz stylus?
