I only looked through these comments a bit and saw a bunch of people saying you might not need an amp. I’d definitely argue you should get an amp/dac combo around the $200 range if you can. I think what you have might power it “fine” but the loudness you will get out of them is going to be severely hindered. Even my old hd598 sounds better with some power than with my phone or computer and it requires less power than what you have
