The Isotek gear does not regenerate the waveform, in other words, it is not an amplifier. I have been to a demonstration and was very impressed with the improvement in sound over not treating power coming from the wall. But, I cannot really say how it performs as compared to other power treatment.
I liked what I heard enough to buy the Evo 3 Sigma for my linestage, music server, and phono stage and turntable, and also a Titan for my power amp and headphone amp.
My only caveat is that the Evo 3 display should be turned off when you are not actually trying to determine the incoming voltage. I left mine on all the time and some of the elements in the display have started to fail.
