Fact: Monster is run by total jerks. Who stink!
More seriously, as a general rule, if something in the audio/videophile world is the subject of a longstanding, unresolved debate over marginal differences in performance improvement -- e.g., Monster cables, power conditioners -- I tend to take it as proof enough that it's probably not worth the money and likely bullcrap. Think about it -- experts of all kinds are totally unable to empirically prove the merit of a given product over years (even decades), and the best its proponents can offer are testimonials like "My picture looks a bit sharper now" or "I hear a bit more detail in the sound." At best, you are forking over an unreasonable amount of cash for a 50% chance that you might
experience a slight increase in performance. Personally, that's not a smart gamble to me, especially being aware of how easily the placebo effect can take place.
Case in point: When I first got a "Game Genie" when I was 12, I popped in a random game ("Spider-Man and the X-Men in: Arcade's Revenge") and started putting in random codes in the hope something cool would happen. Obviously nothing did, but after a certain point, I was convinced
that a flagpole near the start of the game was now almost twice as long, due to one of my random Game Genie codes. It was only when my brother pointed out that the Game Genie couldn't effect changes like that that I realized I was completely just seeing things. Moral of the story? I was really, really stupid when I was 12. But also? People see what they want to.
