I know that's a common question, but with a maximum of 300€ what's the best?

Kind of depends what you want really, I mean at that price you could easily get a digital audio player like the iBasso DX50 or Fiio X3 but if you want more power then I would look into the JDS Labs C5 which is highly recommended.
