When we think of products in terms of functionality they're all somewhat the same. DACs convert digital to analog, power amps drive speakers, preamps control the level. But, that's often where the similarities end. How a product does what it does makes all the difference in the world. The output of an R2R ladder DAC and a DSD-based DirectStream DAC may look the same, but they're not even close in how they got there—nor in how they sound. The same is true for power conditioners. They have AC power going into them, and with multiple AC sockets at their outputs, some modified form of AC coming out. To say or even suggest that a power conditioner or isolation transformer has anything other than form factor in common with a Power Plant would be grossly incorrect. Yet, it happens all the time. We invented the Power Plant concept in 1997. Since that time, 23 years ago, one of our long-standing life's missions has been to help people understand the black and white differences between an active AC regenerator and a power conditioner. The only thing the two have in common is one AC input and many AC outputs. Because Power Plants provide instant dynamic voltage and current regulation along with rebuilding the AC sine wave itself, they are unflinching in their rock-steady delivery of AC power to equipment. A power conditioner, on the other hand, does little to justify its namesake. The condition of the power through a conditioner is, for the most part, unchanged—except to have made it slightly worse in the very areas a Power Plant makes it better. Impedance. (this too applies to isolation transformer based conditioners as well, though they are closer to their namesakes in that they do isolate) Active voltage and current regulation are the keys to reversing what many people fear most with the addition of a power conditioner—loss of dynamics and life. Those who have figured out they're likely better off plugging their power amps directly into the wall socket rather than cripple them with a conditioner, isolation transformer, or any passive device, have exactly the opposite reaction when listening through the lowered impedance of a Power Plant. Just because it walks like a Power Plant, it certainly doesn't sound like one.
