A small voice of dissension here. Since AC noise on the grid can vary, it is difficult for manufacturers to develop a conditioner to address all issues, not to mention expensive. To be sure there are a few: I believe some of the later Mark Levinson gear is supposed to have a power re generator built in, as well as the Halcro stuff. Their prices are rather high, though.
In order to make affordable gear, most manufacturers opt for decent, but not state of the art filtering. My guess is that to admit that, would be akin to admitting that their designs are not good, and I believe some simply ignore the aftermarket units or reject them as being a criticism of their designs. Even today there are no conditioners I have tried (of the affordable ones, that is) that can address every conceivable power grid issue. Some work better than others with some gear, some don't work at all. I've plugged in one conditioner into another for some spectacular gains, but others are not so cumulative and certainly environmental factors change the effectiveness. Even battery powered units change their sound as the batteries discharge and the discharge rate can vary over time (haven't played with the lead acid types, but it certainly applies to lithium and nicad types). And then there are the rather voodoo stuff......
