Good amp for m1060c

Good insert the right expression here,
I’ve just got my m1060c and was totally blown away, but there’s a little problem: I can’t run then neither in my desktop nor my phone (mi a2). I tried to run then with a xiaomi mi 9 and it was pretty good, on my desktop the volume is pretty low and on my phone I can hear some crackling noises. Now I’m trying to find an amp within my budget(115$ or R$600) but I can go a little higher if needed. The only things that I know is that I don’t want to overkill in the amp side, I don’t pretend to get any harder to power headphone and a portable one would be nice but isn’t a must.
Some options i’ve considered was:

  • SMSL m3
  • Fiio btr5 ( don’t know if will be enough )
  • Dx3 pro ( out of the budget and probabilly an overkill )

The main problem with the options that I can only find in USA/EU is the 60% in taxes that I most likely will need to pay, so if I can find on Aliexpress would be nice.
