PS audio PWD MK2 a real upgrade from MKI?


I own the MKI with the bridge and I am considering on sending the unit to PS audio for upgrade, it will be $900, so I decided to ask the audio community to see what is their experience with the upgrades, for me as a full time graduate student every move it has to be done wisely cause I don't have extra cash to be experimenting.
I will really appreciate your comments and personal experience in this journey, the reviews are excellent but I want to hear from this forum before any further move or desition.
King regards and Thank you once more.
