I'm not good at descriptions of a particular sound, but at RMAF 2014 and 2015, Prana was in my top 5 for great sound. He had the new, larger, Vayu model this year and it made some great music. If I had to characterize their sound, I'd say they fall into the laid-back, listen for days type of tonality. I returned numerous times, and no matter what type of music being played, they always served it well.
