“Based on what I heard in two different systems, each with its own challenges and performance envelopes, I can unequivocally say that the GigaWatt PC-4 Evo+ works: It improved the sound of my main audio system by washing away a subtle grain that I could again easily hear when the GigaWatt was then removed from the circuit. My second system, with far worse noise caused by an Extollo Ethernet-over-powerline adapter, was treated even more successfully: the noise vanished entirely.
With exemplary build quality, and its ability not only to power large amplifiers and associated electronics with apparent ease, but to improve the sound of a system by eliminating noise, the GigaWatt PC-4 Evo+ really does do all that a power conditioner can be asked to do. It will meet the requirements of most audiophiles looking to clean up the power feeding their audio systems. I know it meets mine.”
