I decided to get the PP to get a simpler interface for my digital music than my Mac mini. What I didn't expect was to get such a significant improvement in SQ as well. In fact, I didn't think it was possible. After using the PP for two days, I am simply stunned at the SQ. Soundstage is the biggest single improvement as it is now so precise and huge. I have never heard my system sound as natural and real. So far I've used it with MPaD and Tidal through AirPlay. Tidal works marvellously well through it (much better than I expected) and MPaD is a simple and straight forward interface. All in all, I couldn't be happier with this little piece of technical wizardry not to mention the personal support exaSound provides.
