Would I benefit from an amp? (280 pros/58x Jubilee/BL-01 + Audio Interface)

Hello,

I’m an amateur cover artist starting to get into HiFi. My daily drivers right now are the Sennheiser 280 pros running through my Mackie Onyx Artist audio interface. (I own the m50x’s as well but I don’t use them as much unless I want to track with them for one reason or another).
I recently ordered the 58x Jubilees and the new BLON BL-01 as my first pairs of open backs and IEMS respectively and while I’m aware that I would be able to power all those headphones just fine with my audio interface, I was wondering if I would get any benefit from getting a headphone amp and using my Onyx as a DAC instead. And if so, if there are any recommendations mainly for the 58x Jubilee, I’m aware they doesn’t scale well with amps but I’ve still seen people suggesting that it might be a good idea to run them with one.

(I don’t know if the music I listen to is relevant in this case, but I listen to a lot of vocaloid, j-rock, visual kei, and k-pop but always open to any kind of genre)

Thank you!
