Nagaoka MP-150 vs MP-200

Dear chakster, This member wrote to me asking questions about
Signet carts. I own 6 of them among which also TK 5 Ea. I told
him what I know as well that my are for sell. I deed not mention
any price. But I heard never again from him. He is probably
only pretending t be interested. 

@ Nandric I appreciate you took the time to reply. When I messaged you I asked of your opinions about the Signets, as Chakster said you were very familiar with them. Your reply was that you had some for sale, though didn’t mention any pricing. If you can offer insight about how they sound and compare (I know about the history), or even what you would charge for one, that I am interested in.  At this point I am just looking for information.

For what it's worth Nagaoka has their MP-500, which has a line contact styli.

Audio-Technica invented the MicroLine stylus shape.

Nonsense - Namiki patented it in 1983.

I have tried the MP 200 and have it installed on my sister's TT, she seems very happy with the improvement from her Shure Cartridge, (can't remember which Shure it was). I currently have my old MP 30 Cartridge and a new MP 300 stylus installed on the cartridge (they are compatible) and really love the clarity especially in the high and mid frequencies, cymbals, drum sticks on the side of the snare and any  horns. Female voice is also enhanced and more life like.
Just one person's experience, I think it can be a bit of a personal process, hit and miss.
