Polemics aside, aren't many of us thankful for tweaks suggested by others? I am, I ENJOY trying them out and dare humbly submit that many work... (i dare'nt say all & get kicked out of the site).
Regarding science vs voodoo: Jostler3, have you considered that appropriate research COULD provide scientific explanation to alleged differences in sound --- what? all that money for the sake of a few audiophiles??? ...one example I know about: PCords, mentioned in an earlier post. A few years ago, Public Hospitals in France went on-line, and started experimenting in telesurgery. They started raising hell about signals alteration and losses relating to the cabling that linked receiving ends, further claiming that something was wrong with the PPCs power supply and related cabling. The french PPC first refused responsibility claiming ITS networks checked out fine...but as pressure continued (no hi-end alchemists here), they put a team of researchers on the case. Bingo! they discovered that passive (and active) conductors do influence the signal even at low voltage /wattage due to losses related to the cabling surface (can't give you more sci spec, though. I just read the article).
And this is a true story.
