Phono preamp

Currently using a Sansui 4000 vintage receiver in my second system and was curious if the Schitt Mani or any other similar priced SS phono amp would be an upgrade.No problem with the Sansui but we all like to upgrade for better results.Thanks for any information.
Yes. In my case, I agreed that the Mani was fine but with phono, you really have to spend a little more to get a lot better. Sideways moves are just that.
There's a Yaqin 22b phono pre for $100 on Craigslist local but read they had him issues?
What do you consider inexpensive? Under $1500? Under $1000? Under $500? Should it contain both MM & MC sections?
