You can benefit from a DAC/AMp if your DAP is lower level regardless of the impedance. If you have something like DX300 / Lotoo Paw 6K / SE180, you probably don't need a DAC/AMP, or rather it won't improve your experience that much.
I would not get Hugo 2 with no TypeC in 2021, they are making a Mojo 2 with TypeC to be released at the beginning of next year, and around that price there are some great other options too
I personally have been using the Cyrus One Cast ridiculously much lately, I like how it sounds and works as the main DAC/AMP for my PC .
