You are correct. ??

This is hearing my familiar music but not my working tuning music, and only with a low end headphone which only recieve 50 points from Dr. Sean Olive's predict algorithm.

If I use my tuning music and Mark Levinson system, I think I can keep 24 level 100% accuracy rate all the time.

And the last listening test is default test program, also very easy to get 8 level with 0 error.

And even this, I think my subjective evaluation ability is just very general in Harman ASE team. And I never dare to claim I'm golden ear and I can hear difference below human or audio precision test limits.
