From a business perspective, I thought RMAF was better than the regular CanJams (note I did not go to RMAF last year). And there was plenty to do outside the show as well.
For me the biggest difference is people didn't stop by my table to be overly critical of Amp A vs Amp B or anything like that, like they would from Head-Fi. People were blown away by the sound from the Omega II, and they would have been at any table. So overall it was a more positive experience for the people involved
