there is a first test of the Master 1 in the german hifi magazine Test:

it did get the highest score of 97 points within the headphone section; from remembering: also some other headphones have been scored with 97 points; Stax 009 has not been tested yet
I know, it is only a test, but it is close to my own impressions
I'm wondering why Pioneer did not label this headphone under the High end label TAD (Technical Audio Devices); maybe it is still not expansive enough
to me, the sound/cost relation is excellent!
