Audio Performance Improves Exponentially When You Treat Its Foundation: The Electrical Source
Virtually all high-quality audio components include large transformers, sensitive capacitors, and filters. When AC power, which travels in two directions on your line—it enters components through the hot wire and exits through the neutral wire—enters your gear, it is converted to DC through a rectification process.
Not all the electricity entering your component is utilized; some unused power may filter back onto the line as noise, aka DC transients. In addition, unused AC power that travels back from your gear to your electrical panel is subject to intrusion by EMI (electromagnetic interference) and RFI (radio frequency interference). This interference reduces frequency harmonics, inhibits the current flow, and produces power fluctuations that prevent audio gear from operating at its full capacity. So-called “dirty power” invariably impacts system performance.
Other than resorting to battery power, there is no way to stop the system-degrading noise process described above unless you enlarge your electrical conductors and strengthen your ground. That is the purpose of the AU Ultra Series 3000: it is an audiophile-grade subpanel that sits on your rack, reduces the distance AC power travels between your breaker panel and equipment power receptacles, enlarges the conduit, improves grounding, and lowers the overall impedance of your current to enable the increased electrical flow.
The easiest way to describe the before / effects of an Ultra Series 3000 is to imagine trying to sip an ice cream shake through an ultra-thin coffee straw. The process is inefficient. You must work very hard and expend a lot of energy to enjoy more than a dribble at any one time. Now imagine the alternative: a recyclable straw with a far wider diameter that, with little energy expenditure on your part, efficiently delivers all the shake and satisfaction that your heart desires.
