Replaced my Ortofon Blue stylus today via plug and play swap in seconds


So their styli housing just pulls off the cartridge. New one slides on. Truly that easy. Takes seconds.
 
My question here is simple: do any other brands allow this? If not, why not? The design is so brilliant, so logical, I'll use this for life (plus it sounds good).

All Moving Magnet and Moving Iron cartridges allow this.
Stylus is user replaceable on all vintage and modern MM and MI cartridges. 



Walter O. Stanton is the inventor of an easily replaceable phonograph stylus. In the late 1940’s Mr. Stanton’s slide-in stylus made it possible for users to replace a needle assembly when it wore out, instead of having to send it back to the factory. Audiophiles snapped them up for home use, and the invention became one of the basics in phonograph cartridge design. But Mr. Stanton was as much a salesman as he was an engineer. In 1950, he bought Pickering & Company, the audio component manufacturer that first sold his patented stylus. A decade later he founded another company, Stanton Magnetics, which was one of the first American companies to make and sell magnetic cartridges that improved sound quality and allowed for a less-expensive product in the 1970’s. Both companies had operations in Plainview, N.Y., and West Palm Beach, FL.

This is wrong. There are some MI with non user replaceable stylus.
@dover there are some MC with user replaceable stylus too if you don’t know, but who cares about exceptions.

99.9 % MM and MI have user replaceable styli and this is a huge benefit.
99.9 % MC does not have this option.

Now you’re happy?
Not all MM cartridges have a user replaceable stylus.  My Grado Sonata does not and neither do the upper end cartridges from them.   I don't know why, other than they want you to buy a new cartridge when it wears out.   There are many others, too - definitely not 99.9%.   Majority?  Probably, but I haven't a clue what the percentages are.   It does appear at first glance the more expensive cartridges do not have a replaceable stylus.  
Clearaudio Virtuoso Wood is a moving magnet that requires you to send it in for rebuild but in reality the stylus can be replaced easily by the end user with very little effort. Makes me wonder if some of the other MM and MI carts that are said to require factory service to replace worn stylus don't fall into this catagory. Enjoy the music
