Is there any evidence that changing power source components, when you have normally functioning power in your home, will actually produce a change in audio quality? Any ABX tests I can find say it's bogus, but I'm always open to additional evidence whether for or against.
dqnielThe Head-Fi review linked in the description for this item covers this topic fairly well. I think at this point it's well established that power improvements only make a difference when there's an issue that can be improved upon. The question is, do you really have perfect power? At least in my case voltage dips occur regularly and there is a not insignificant amount of ripple. Both of these can be alleviated by power conditioning, and the additional surge protection is helpful because of followup voltage spikes.
