Dear @puppyt : I can see that I'm late in your thread and you already pull the triger on the tonearm and seems to me that your first step should been to choose the new cartridge you want to own ( as the Umami Red. ) and then look for the tonearm that can match it the best inside your budget.
Anyway, maybe the Delos playing hours are to much or the cartridge/tonearm set up is not adequated yet.
You need to chek with a good protractor the cartridge/tonearm alignment and after that and trhough " test and error " process makes a fine tunning with the other cartridge set up parameters as: AZ, VTA/SRA, VTF and the like In the other side the internal tonearm wiring is new and needs some time to settle down.
Regards and enjoy the MUSIC NOT DISTORTIONS,
