So what you're saying is there's an elaborate conspiracy with different models, part numbers, names and prices which has been going on for decades? When all someone would have to do is switch stylus's to find out? And no reviewer or magazine has discovered this in 30+ years, but you have?
And the proof you have is someone comparing a worn out gold to a new blue stylus listened to at different times?

Grado is a small family owned company in there second generation. During the time they have been around many companies have went into hard times and changed ownership. When this happens many times the owners of older product get left out in the cold. Shure Brothers, Denon, Thorens and Dual all have changed hands.
Grado has went out of there way to take care of there customers, sometimes from decades passed and has consistantly garnered excellent reviews in the perfectionist press.
To claim this fine small company is misrepresenting there products on subjective non scientific evidence on a forum of 20,000 people is'nt just unscientific it's irresponsible. Grado sells about $500,000 worth of cartriges per year; if 500 people listen to you Grado could loose approx %10 of there cartrige sales. For a small company that's a big hit, and they have supported the hifi community for decades, almost going under a few years ago. Grado has always had affordable products in there lineup, not what you'd expect from a greedy dishonest company. But it is what you'd expect from a company interested in long term relationships.
I don't doubt that people have heard what they say the've heard. In a-b comparisons I have heard only small differences when comparing products myself. It's another matter to claim
Grado "take two identical styli...
and sell them as two different items...".
This to me is making a leap in logic which has not been proven, and could hurt a company that's supported the vintage community.
Different part numbers doesn't prove anything. You can take two identical styli, put gold dots and one part number on one and blue dots and another part number on the other and sell them as two different items, which Grado very well may do.
Really? Give me the quote from a post in which an AK member tried different Grado styli in the same cartridge and heard a difference.
