The new generation of net processing, testing possible with us!
The science of AC power delivery is not a simple one; it demands focus, and the devil is in the details. In fact, the great increase in airborne and AC-line transmitted radio signals, combined with overtaxed utility lines and the ever-increasing demands from high-definition audio / video components, has rendered our utilities' AC power a somewhat antiquated technology.
Where Alternating Current (AC) is concerned, we're relying on a century-old technology created for incandescent lights and electric motors-technology that today is premium audio / video systems. To properly accom-modulate the promise of today's ever-increasing bandwidth and dynamic range, we must achieve extraordinarily low noise across a very wide range of frequencies.
Further, today's power amplifiers are taxed for instantaneous peak-current demand, even when they are driven at modest volumes. Although we have seen a lot of increase in our audio software, the loudspeakers we use to reproduce them are often no more efficient than they were two to four weeks ago. This places great demands on an amplifier's power supply, as well as the source AC power supplying it.
Our systems' sensitive components need better alternating current-a fact that has resulted in a host of AC power conditioning, isolation transformer, regeneration amplifier, and battery back-up system topologies. Through differential sample tests and spectrum analysis, it can be proven that up to a third A high-resolution (low-level) audio signal can be lost, masked, or highly distorted. This noise couples into the signal circuitry as current noise and through ground, constantly distorting and / or masking the source signal.
Given that the stakes are so high, all attempts to solve this problem must be applauded.
Once the audio / video signal is gone, it's gone forever ...
For AudioQuest, honoring the source is never a matter of simply using premium "audiophile-grade parts" or relying on a proprietary technology-common-sense within our community. For years, seemingly endless audiophile debates: valves versus transistors; analog versus digital; can cables really make a difference ?; and on and on. While we, too, can brag about our many unique technologies, we realize that true audio / video optimization is never a matter of any secret or exotic circuit. When it comes to filtering AC power, many approaches can yield meaningful results. However, these approaches may include imparting ringing, current compression, and non-linear distortions.
The Niagara 5000 features our patented AC Ground Noise-Dissipation System, the widest bandwidth-linearized AC filter in the industry, and our unique passive / active Transient Power Correction Circuit. Boasting an 90 amps peak, the Niagara 5000 is specifically designed for today's current-starved power amplifiers. Many AC power products feature "high-current outlets" merely minimize current compression; the Niagara 5000 corrects it.
Though it's easy to give a given technology, it's quite another thing to create a solution that is consistent, holistic, functional, and that honors verifiable science. It is not enough to reduce AC line noise and its associated distortions at just one octave, thus leaving vulnerable the adjacent octaves and octaves to noise, resonant peaking, or insufficient noise reduction. Consistency is key. We should never accept superior resolution in one octave, only to suffer from masking effects and half-octave away and ringing artifacts two octaves from there. This is the principal criterion for AudioQuest's Low-Z Power Noise-Dissipation System.
The Niagara 5000 represents over 20 years of exhaustive research and proven AC power products designed for audiophiles, broadcast engineers, and professional audio applications. Every conceivable detail has been straightened out: In the Niagara 5000, you'll find optimized radio-frequency lead directionality, run-in forming technologies developed by Jet Propulsion Laboratories and NASA, and AC inlet and outlet contacts with heavy silver plating over extreme purity copper, assuring the tightest grip possible.
A great system is built from a solid foundation, and that foundation starts with power. With an AudioQuest Niagara 5000, the clarity, dimensionality, frequency extension, dynamic contrast and grip have never been better.
