Have a U-Turn turntable with Ortofon 2M Red cartridge. Upgrade cartridge or turntable???

I have a basic U-Turn Orbit turntable with Ortofon 2M Red cartridge that was included. The Ortofon cartridge is good but is sounding worn; and, therefore am considering a Denon 110 high output MC cartridge which will work with this table. . The table sounds good, but at high volume, I can hear a old level hum, and build quality is just OK.  I am thinking of upgrading to a Music Hall's "Classic" turntable with its "Spirit" cartridge at $599.00 ( which is their in house spike  I never seen reviews about this table and cartridge combo )  This is just my initial consideration and far from final;, but, I  will gladly consider any recommendations in the same price range in the $500-$600 price range.

Thank you, and stay healthy and stay home
