Panamax MAX® 7500-PRO Home theater power regulator, conditioner, and surge protector at Crutchfield.com I was in the market for a new power conditioner. I know some people believe them to be snake oil, but I can attest that they did help reduce noise issues I have had with equipment. I will also note I picked one up and I didn't hear the transformer noise that some people were reporting. Either way $699.00 is a lot less than pretty much every place I have looked.
