Someone above mentioned Dynavector. That is a perfect upgrade in terms of cartridge. 10x, or 20x. Whichever you can afford. You will get no noise issues with that Dynavector. Rega grounds differently than some other tables and you can get some noise with Grado or say Ortofon Cadenza cartridges.
Then get the best phone stage you can. Once you move away from Rega cartridges, you will find that Rega phono stage will not deliver at the same level. Not sure where your budget will fall. Vet with the group here to flag any big issues in terms of quality. There are a few units I can think of that would be in your budget that I would avoid as not very good.
Chord, Musical Fidelity and Rogue are all very safe in terms of phono stage quality.
