TIDAL was exhibiting at the CES 2011 in Las Vegas

"Germany's TIDAL Audio proudly displayed the Sunray loudspeaker, an assault on the state of the art. 
The TIDAL Sunrays are simply beautiful-sounding loudspeakers. 

I heard two pairs of Sunrays at CES 2011 (they were playing in two different rooms), and their strong points were clear: holographic soundstaging, three-dimensional imaging, and seductive musical subtlety, particularly in the high frequencies.

I was struck by how much depth-of-stage they could reproduce; they made me want to get out of my seat to mingle with the performers."
