New level of ridiculousness

I wonder how much one would go for used? That would be a good indicator of actual value. Much of it in this case would probably be due to aesthetics more so than function i would wager.

"There is nothing wrong with improvement thru placebo effect as long as one can afford it. "

A significant portion of what we hear and how we respond is determined by the final component in the signal chain, our own mind and bodies, so I would tend to agree.

The fancy powerstrip is probably more functional than the diamonds our wives might covet. Still, they will choose the diamonds. Go figure!

Seems like it should be better for TV/video as well. Seeing would be believing. More so than hearing I think. IS hearing alone enough to believe? Not as easily I think. No need to go into all the shortcomings of using a/b listening tests alone to establish a products value.

Also a technical explanation of how why this power device works its magic would help in this case. Power conditioning isn't rocket science. There must be some basis for how it works beyond a suppliers magical ability to hear good things.

"I don't know whether your supposition about vision being more sensitive than hearing is true"

Not necessarily more sensitive,just easier to assess differences with video versus audio I think.
