sorry ,i know a little englishThe acoustic field of technics900 is open! Far from D777 than! XPS900
The high pitch is better than 777, a kind of elegant feeling. There is little XPS900 low volume, the ones that but left and sneaked are deep
The bass of D777 sounds really very enjoyable, but there are too much quantity! D777 in addition
dental too is the serious,very it is the unpleasant! The acoustic field of 777 is not very good ! 777 has been opened low
Will bring the noise after the sound !
In China, to hear from edition owner on the forum XPS900 have top-grade platform very much with oneself us
Feeling of the type machine!
