Millercarbon said it all.
My addendum:The most economical route may be to keep on upgrading arm and table, while having a cheap(er) cartridge that can step up big way.Not all cartridges can step up when the table/arm combo is greatly elevated.I found the Audiotechnica ATF7 is such a hidden gem. Totally inexpensive LOMC cartridge, as cheap as LOMC can get. I got it as a backup cartridge to test play my second hand records. On the big table it plays in big cartridge league, and each improvement on arm / table / step up made it step up higher and higher. Athough, I have to add I never tried it on the Rega or other cheaper tables / arms, so don't know how it performs on a cheap table... but that's kind of out of the question as LOMC step up on the cheap is pretty bad. In the low price range MM is the way to go. A cheap MM cartridge that can play big time on big tables is the AT440MLa or MLb. (good luck finding MLa version! But sadly even the AT440MLb have become quite expensive now, while 20 years ago it was a cheap(ish) cartridge!) On a basic table (Rega P3, with Rega arm) for example the AT440MLb and the Grado Prestige sound quite in the same league - different presentation style, but similar performance. Put them on a big VPI-caliber table, and the AT440MLb skyrockets and the little Grado falls apart. The ATF7 is cheaper than the AT440MLb, yet on a big table it completely eclipses the AT440MLb. Yet, the AT440MLb has nothing to be ashamed of either, and its lifespan and durability is absolutely outstanding.
