Good evening,foreign reader from head.
Please forgive my poor English.
and, thank you for giving the article on stereophile.
but, measurements of stereophile were greatly different from my measurements, and I was perplexed.
First of all, i thought there was a problem in my measurement (CLIOWINfw).
And, the pure resistance was measured for the calibration.
As a result, the measurement error in the range from 20 to 20kHz was within 1%, and the problem was not found about the range from 100ohm to 800ohm. (The pure resistance used as a calibration is accuracy 1%, and the resistance is 100ohm, 200ohm, 300ohm, 400ohm, 600ohm, and 800ohm. )
Afterwards, it was the same as the result of the measurement the other day though I had measured the impedance of HD800 again.
Please refer to here for the result of the calibration and re-measurement.
