Yup...The video was not made to sell to musicians but to crazy audiophiles who spend buttloads of $$$ on gear ...so for the audiophile suffering with GAS cool... I found it interesting to convert AC to DC and then back to AC ..probably wouldn't cost all that much to get that set up for a small studio. I was having a ton of noise issues with one of my keyboards but it turned out to be solder joints going bad on the motherboard. Because it was a newer keyboard I ran a whole new circuit from a new panel with a bitchin ground trying to eliminate it before figuring it out that it was the keyboard...Oh well nice fresh electrical to the room now.Yeah, but, like he said, unabashed sales pitch.
