If you buy it, get the Pangea P100 power supply also (once it's available...they need a proper size P100 cable as the one supplied for the DACMagic won't fit the "plus"). I imagine it will be offered (from Audio Advisor) as a package deal although I bought P100s for my DACMagic and 650P phono pre from Amazon to save shipping fees. Based on all this, I'll likely buy the "plus" eventually although since I don't currently need the usb feature I'm in no hurry. You can read about the P100 in the new Stereophile.
