Noise reduction devices, as I’ve learned, have a cumulative effect. I often say “the more the merrier” with grounding hubs and isolation platforms and power conditioners and network switches because I haven’t yet reached the point where I’ve felt things couldn’t possibly get any quieter. Then I try something new, and I hear an even more profound lowering of the noise floor and I know there will always be room for improvement. The GigaWatt PowerMaster, however, convinced me that I could remove most of those other devices from my system and the results would be remarkably similar. That’s a broad claim to make, except I can back it up by saying I did remove all of noise reduction devices from my system except for the PowerMaster, and I still felt I had heard the single most effective product for power management I’ve used. Highly recommended.
