Just my 2 cents worth about my own personal experience. I had two of the original Tice Power Blocks and Tice Titans that I imported into Hong Kong new from the States around 1991. I found them terrible. They significantly rolled off both frequency extremes and thickened the midrange. I cannot think of one plus compared to plugging my gear into pac idos outlet strips which I understand simply dump noise from digital devices to ground. If you have the original Tice items, like any power conditioner or outlet strip, I would recommend that you compare them with going straight into the wall. I have no experience with the Mk III.
