I was mesmerized by the Volti Audio Rival II Horn speakers. That SET amp and those horns were wonderful sounding. I think the little DAC was also quite impressive.
The other speaker that left an impression on me were the granite Acora speakers. I walked into that great Hall and saw these two diminutive granite towers that just didn’t seem to go with the great sound filling this giant space. I went back that evening to hear a talk about the 24 Channel mix tape of Bohemian Rhapsody and marveled even more at the bass these speakers can deliver. The Mastering Engineer presentation was interesting and informative as well.
