Here's another review: http://www.lesnumeriques.com/platine-mus.../test.html

It's french however, but fairly interesting measurements. There seems to be quite a bit of distortion below 150hz.

Can you help me to read the harmonic distortion curve? Reading the text (less than 1% above 150 Hz) I interprete harmonic distortion below 150Hz goes to 4%. This would be extraordinary. Normally speakers have about 30-50% harmonic distortion at these low frequencies. What does the y-scale mean 0-10?
