Need recommendations for new ananda stealth

So I just ordered a pair of ananda stealth, but I’m wondering if I should invest in an amp. I currently use the focusrite 2i2. If that makes any difference, I also have a pair of focal alpha 65 (speakers) plugged in the interface. Would that be a problem? Do I need the output of the focusrite for the amp?

Would I see a difference in sound quality since the ananda are easy to drive. I have dt990 250ohms right now and have no problem driving them.

If you suggest me to invest in an amp, which one would it be if I’m on a budget. Should I wait to receive the ananda and decide afterward?

Thank you!
