    We can make additional achievement badges for the following:
    1. Listening room at 10dbA SPL.
    2. Ability to detect harmonics 100db down

    Because you haven't hit -100db distortion on the test yet.

    Done during the night at normal listening volume. My hearing is crap during the day. Can't avoid some background noise.

    -24/27dB, T. Chapman, JVC Flats (with Dunu 75 ohms impedance adapter)
    -30/33dB, T. Chapman, modified GMP400
    -30/33dB, J. Stone, modified GMP400
    -42dB, two-tone 70-800Hz, modified GMP400

    Both headphones driven by a Meridian Explorer 2, not ideal for the GMP but whatever. With the JVC Flats the -24/27dB range was about as difficult as the 33/36 range on the GMP. The nature of the differences changes as the distortion goes down. Too much time in my hands...
