Yep the fancy "audiophile grade" filters cost a lot , normal fillters don't and they do exists usually for installation inside compenents. Equipment dependent yes :) pssr "power supply rejection ratio" vary wildly . You would not be surprised to find that woo woo audiophile components with exotic design actually does not excell here ,rather the opposite . Seems like some tube designs and other no feedback designs actually demands beefier power supplies in the first place and are more likely to be sensitive to mains noise too ? So by woo woo design you make components having problems that where solved decades ago ? IMHO it's a myth that it is always smps power supplies that dirties the network , linear supplies can do this too and some smps supplies are decently filtered and do not pose a problem . A bad power supply can polite the mains . ( OT why does not modern amps use atleast LC filter most only have capacitance after the rectifier bridge , I work with lVSD drives they all have a main inductance besides it capacitor bank , economy decides if it's placed on the AC or DC side ) An example of a bad supply is probably the 230Vac supply that was delivered with slimdevices branded SB3 . The logitech branded classic has the Touch supply that atleast confirms to some norms about noise etc , and probably is less likely to disturb sensitive components. One of the cheaper upgrades I had was simply having ground at the hifi outlets , this will probably surprise someone front a Great Britain as they always have line neutral and ground present in all outlets ? -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
