After reading about the merits of such upgrades-both positive and negative opinions, is there anybody who can offer some scientific facts that back up the claims that a vast improvement ( or significant improvement ) justifies the rather large amount of cash for such things? Or, as I suspect, they are mostly gimmicks for the audiophile that has too much spare change lying around?

Besides looking good, is thier a positive change in the MUSIC? Just curious how this site looks upon these upgrades.

Thanks to all! Happy Holidays!!!
