All in all, we hereby provide the suggestions as follows:

  1. If you are a stacking enthusiast, there is no doubt that the Non-amped module AM0 is your choice.
  2. If you already have 2.5mm balanced headphones/earphones, then go for balanced type AM3.
  3. If your headphone is not balanced type while with high impedance, then high-power type AM5 should be your first choice.
  4. If you mainly use earbuds or portable headphones, you may choose the Medium-power type AM2.
  5. If you only use earbuds with much care to its heat dissipation and battery life, then you may choose the IEM type AM1.
