I have one of the noise "meters" demonstrated in the video - sound plus numeric readout. I just want to caution all that the exact same results can be realized with the $250 Monster Power Bar I bought in the early 1990s. Now I have no doubt that Shunyata, Equitech, et al have far more sophisticated devices, but I'm not sure an objective, measurable demo will lead you to an answer. I, myself have Exact Power conditioning on all my source components, but I don't condition my DSPs. Years ago I had a pair of high current of PS Audio Ultimate Outlets, but I don't believe they made a positive sonic difference. Many good amplifiers have excellent common mode noise rejection (Meridians DSPs do), which is what these transformer-based solution provide.
