  • This audeze article does a better job explaining the terms and how they relate to each with regards to how much power is needed better than I ever could.

    It kinda does but IMO only to a point. And that point is where they claim that your amplifier should be able to handle transients that are 50 dB louder than the average SPL.

    It would mean that if you listen to music at an average SPL of 80 dB, your amplifier should be able to output enough power for peaks up to 130 dB.

    Let me give you some examples of how much power would that be for some headphones (based on measurements from SoundStage Network or RAA):

    ~60 mW for very sensitive IEMs like KZ CRN.

    ~1.3 W(!) for a low sensitivity planar IEM like 7Hz Timeless.

    ~1 W for popular sensitive headphones like ATH M50x.

    ~126 W (a hundred and twenty six Watts) for one of the least sensitive headphones on the market like Hifiman HE6se.
