For years I have used the Mapleshade power strip/conditioner with excellent results.
However, recently adding the Machina Dynamica Flying Saucer for wall outlet next to the power strip and to other unused AC wall outlets has further upgraded both the analog and digital performance in what amounts to a major upgrade.
As mentioned by Tboooe, there can be tremendous potential within existing components waiting to be unveiled.
My own vote goes to Machina Dynamica for great results at reasonable cost.
