The cable elevators experiment seems immune from a charge leveled at so many tweaks that are castigated as "snake oil" -- as albertporter and other point out, you can try this yourself, with anything you have at home.
So why the vitriol? With expensive tweaks, you can imagine folks getting hot under the collar that someone is trying to filch their money; but with a nearly free one -- no reason to get bothered.
The only reason I can imagine I'd be bothered is the idea I might try it and not hear something that others hear. That would mean I was deficient in either hearing ability or listening ability. I've tried to pull myself back from this by remembering that those who can hear or listen better than I can may also write about it and give me something to reach for. I remain open to this idea until I get no results.
