The SR guy is a joke with zero qualifications to create anything other than overpriced junk that requires no customer support or maintenance. His background is 100% marketing.
Sadly, the hobby is littered with gullible people who pretend to be knowledgeable and desperately fall for his marketing tactics and demos.
He hides behind that 30 day guarantee like a late night infomercial because he knows he'd be an FTC target otherwise. It's a marketing tactic where a healthy amount of returns is already factored in the price. Plus, he knows most people won't go through the trouble of disconnecting fuses, outlets, or admit they were wrong and fell for his ads and hype.
Nevertheless, SR does provide a side benefit. I like reading threads on audiogon about SR because the comments tell me who is clueless and who to never trust their "advice".
I can't wait until a year or so from now when he creates a purple fuse or outlet, and we see more mindless audiophiles rush to the forums to evidence just how gullible they are.
At least the cheap quality fuses and outlets he makes aren't seen by most people. I especially appreciate those crazy enough to stick his black box of nothing in the middle of their room and pretend it's defying physics and attenuating low frequencies...or better yet... The atmosphere room thing that does ZERO except gives you a different picture to look at on an app in hopes of subliminal conditioning...or most comical are the ones that take random amounts of blue tac and stick it to the back of $.01 nut-sized things and sprinkle them all around their room pretending that it improves the performance of Magico speakers.
