Got mine today (APS modded and recabled). Sounds damn nice out of the y1 and T1S (haven't tried with the E/90 cause it is not set to EU voltage) but I guess with the Pico it will be better (I will compare the two).
Only trouble is, when I move my head, it is a bit noisy, maybe because the the fit is not optimal for my big ears. I had some issues with the LNS as well (with old pads) but not with the almost brand new SR-404 that I listened to a while ago.
