RE: iFi DC Purifier usage with KingRex linear PSU

I'm using the dc ipurifier on my xfinity x1 box ( which also uses a switcher ) and it does improve both the picture and audio ( in my system ), but I also have the dc cable wrapped seceral times around a large nanocrystalline torroid, and have a shakti stone sitting on top of the box. He newer cable boxes are light and acoustically, as well as electrically noisy. A linear supply probably would be better, but I don't have one on hand that meets the requirements.

As far as the dc ipurifier improving a linear supply, I suppose that depends on the quality of the linear supply. It did improve my Virtue 1 amplifier, but the linear supply I'm using with that is not of the highest quality. I suspect many of the less expensive power supplies are not well filtered and can pass along noise from the ac as well as diode switching noise. For the price, I think it's worth trying, but only you can decide if it would be for you. Good linear supplies are not cheap.

I have absolutely no experiance with the device you originally posted about, so no opinion on that.
