I used 1 for 8 months , i didnt know any better
Some of the cartridges I've owned quite recently; Nagaoka MP-200, Nagaoka MP-100, AT440MLa, Stanton 885 LZS, Pickering XV-15/625E, Denon DL-160, Goldring Eroica and whatnot.. many more.
Not any of them do the same thing AT95E does. I also had the AT95SA (shibata), but sold the stylus quickly. While the Shibata stylus does indeed track cleaner, it's also leaner - in the wrong way IMO. At least in my modest setup.
AT95E isn't perfect, far from it, but many of those so called tracking/tracing issues with the cartridge are really just about bad records, bad setup, cheap/poor turntables. People just don't seem to be bothered "as the cartridge is so cheap".
When it comes to tracing the inner grooves, that styli profile thing is only half-true (if even that). The quality of polishing, the quality of diamond and the cantilever play much bigger role - actually those so called "scientifc" papers commonly spread in internet about stylus tracing present rather unrealistic situations and way too hot grooves. They rarely - if ever - exist in real life!!
While AT440MLa distorts less than AT95E, it isn't a problem free design, and has little to do with the way the stylus is cut. Many people are IME AND IMO under the misconception that stylus profile is everything and is the major cause for poor tracing. It is not.
Now, I'm making some outrageous claims here, but anyone can refer to vinylengine.com and some of the discussions that have been going on there for years about styli and their profiles. While the quality of written content in that site is questionable to some extent, there are people who have talked against these marketing schemes about styli profiles, and have convinced me to some extent. They've also provided data. My experiences support this.
Being a skeptic, I never think things final. My own experiences are very narrow as well, and I present my findings naively. I just wanna make few opposing points, because I don't want people to take these things for granted.
AT440MLa might solve IGD in this particular case, but will it introduce some other issues? Finding a good cartridge is really hard - like really really hard. Maybe Linn is the answer, but I don't know just yet. I have NEVER heard a cart that can track 100% correctly, but that is just the issue with vinyl I guess. Nothing is perfect, I enjoy this format and AT95E allows me to do so - most of the time.
