Hearing the 1plus2 with the gold cable and Astell&Kern AK100, loss less PCM 48kHz/16bit. There are more details to hear as with the Grado PS1000. The bass seems more accurate (dry) and overall the sound more neutral. Bothe are fantastic earphones. Soundstage of the 1plus2 ist awesome and I don't miss the soundstage of the Grado, which is not bad at all... But the earphones needs a long burn-in time (mind. 200h)  to sound smooth an no more harsh as at the beginning. Other earphones I have in comparison: Weston 3, Shure 530. Both nice, but the 1plus2...
