Do I really need a power conditioner? I've been a audiophile in the distant past - and with all of our computer equipment all we use are surge suppressors. We have yet to ever have one of those devices trigger. Plus the high end power filter/surge supressors appear to be fancy looking gimmicks that the manufacturers dreamed up. Anyone share my suspicians about these - or alternatively - does anyone have conclusive evidence that we need these? It seems pretty absurd that we would NEED these with our sound and video equipment. What are your thoughts???
