PSA DirectStream break-in time.
I have a PSA PWD MkII. After two weeks of break-in I was ready to return it. Hard sounding treble, thin bass. My vendor said they took a long time to sound right and that their worst sound during break-in was after two weeks (powered on 24x7). After the two week mark, it started sounding better and after a month, the treble was clean, relaxed, extended and the bass was tight, deep, and musical. I don't know if the DirectStream settles in faster, but this is just fyi from my experience.
