RSX Technologies Power8™ AC Power Box $429 Review

The first graph shows the resulting noise level coming from the amp and speakers using a standard generic power cable that was supplied with the KECES amp. No content is being provided to the amp. This is simply the noise floor of the amplifier, measured just in front of the speaker. The second graph is the exact same setup, except the power cables have been replaced with RSX Beyond Power Cables running through the RSX Power8/Beyond™ AC Cables.
