Is there any real point in upgrading from my Modi 2 Uber?

Hello everyone,

I'm currently using my >3 year old Modi 2 Uber over optical because the USB port stopped working about a year ago. I've been thinking about upgrades lately, but was wondering if there would be any increase in sound quality if I got something like the JDS OL DAC to replace it, or the Topping D30 that a lot of people seem to talk about.

Sorry if this is a stupid question, but I wasn't sure where else to ask, and I don't want to go throwing money away if I don't have to.
