Presuming your 20x has some milage I would maybe look to an outboard phono stage. 1st the 20x is a pretty good cartridge. 2nd, presuming you are using an inboard phon, if so I am not familiar with it but, two outboards I have listened to that I think would give you a noticeable upgrade.
1 Dynavector p75 or the new PS Audio unit. the PS edges out the p75 on pur dynamics and bass extension but the p-75 way out performs its price range in tonal accuracy, timing and transparency. Factor in cables and you in your range.
