Many things can be done for upgraded sound . You haven't mentioned acoustics . If you have not fooled around and invested into a better sounding room then thats where you should start . Carpets , drapes , tube traps , whatever needed . It could make a much bigger differences then any piece of equipment or tweek .
You have an integrated . Many sound very good but a Good pre power combination will in my estimation sound better . Unless you have something like a Plinius , Mark Levinson or Pass integrated separate units will sound better , although not all , you still have to be careful buying . Your Rogue Audio for the price is very good but even Rogue have their separates .
You can upgrade your cartridge but in order to be able to extract best performance a better tonearm might be necessary . You have a very good turntable . Experiment with mats .
Your phono stage seems to be excellent . To finish , cables . I use and will always recommend JPS Labs superconductors . They are excellent and sound great with tubes or Solid State , be it speaker cables , intercomnects or power cable . Their Aluminata series are superlative.
Hope this helps
God Bless and stay safe .
