Does the Hifiberry DAC work when running RPi with 3.3V

Hi,

inspired by your HiFiBerry user Fred from France (http://www.hifiberry.com/2014/05/an-audio-streamer-with-digital-output/) I want to use an external linear power supply for optimal audio performance.
Unfortunately, the RPi has an internal voltage regulator for supplying most of its components with 3.3V – but it can be bypassed regarding to Dave Akerman:

So my question is: Will the Hifiberry DAC work when the RPi is powered with 3.3V instead of 5V? Has anyone tried this?
