Transforms room acoustics using an iPad as remote control. NOT PART OF THE SIGNAL PATH. https://www.youtube.com/watch?v=EMb0AWJTdwY Did ya see what he did there? He planted expectation before he turned it on, dropped the volume about 1dB when he turned the fake gizmo on, and then provided a dandy offscreen person to reinforce the expectation bias! This guy is as good as Penn and Teller. Would someone like to grab the two samples off the video, normalize them and post them online for us to compare without all the planting of expectation?
