Inexpensive MM Cartridge

Thanks everyone for your excellent advice!  This is a thread I will keep aware of.  I ended up getting a really good deal on a demo Nagaoka MP-200 from a trusted dealer, but from the posts above, it may be better than the rest of the system benefit from.  Oh well.  Perhaps there will be another TT that comes into the throw, and we can swap cartridges. I think this thread will help others in a similar situation.

peter s. Good luck in your searches. Turntables are one of the most challenging items in the analog world. Tables can be bought with a preinstalled cartridge. If from a trusted dealer then those cartridges can be mounted in a correct manor. However, mounting a cartridge is a most important thing. Factors such a overhang, alignment, tracking force, and others are critical as to how the end sound is. Switching a cartridge from one table to another takes all these factors into account.

Buying a cartridge to see how it performs, and if it's not satisfactory, then getting another turntable and installing the "before" purchased cartridge may not be the best path to pursue. May or may not sound better? An upgraded cartridge on your table may not be any improvement at all. Then...where to go? It all comes down to the rest of the system. Importantly is the phono stage, whether it's a stand alone or built into the amp? Does the Pioneer table, although recently serviced, have an upgraded power cable and interconnects?
So many things to consider. If I were given those options I would try to audition a new table with installed cart with the existing system. That's the best way to determine the path to take.

I think the Grados are highly overrated, with a tendency to murkiness with a subdued high end.  The A/T's may be a better choice in this price range.  Or the Ortofon 2M Blue.

Peter_s, I've been very happy with my Nagaoka MP-200.
It didn't take long to break in and it's a lot of cartridge for the money.

Shure  v15 on the used mart. The best you can afford. No brainer with that tt.
