Is it worth upgrading my current turntable setup?

Hello all here is my current system

Pioneer PLX-1000 turntable w/ Ortofon 2M Black cartridge

Tokyo Sound PE 100SE phono stage

Aric Audio Unlimited tube preamp

Odyssey Audio Khartago SE amplifier

Divine Acoustics Proxima 3 speakers

Do you think the turntable is holding back the rest of the system? Thanks for any advice!
