Just because you heard the speakers at RMAF doesn't make them better, it all depends on setup and room acoustics.
Both of these speaekers are excellent, if you want to really know the answer you must consider what kind of gear were they using?
From what I see your equipment selection is good, but could be better. I have heard the Syncroney's sound great on higher end setups.
To me this is a lateral step at best, both of these speakers are good in different ways.
