The science of AC power delivery is not simple; it demands focus, and the devil is in the details. In fact, the vast increase in airborne and AC line radio signals, combined with overloaded utility lines and ever-increasing demands for high-definition audio / video components, has made the power of AC of our utilities is somewhat outdated technology.

When it comes to alternating current (AC), we rely on centuries-old technology created for incandescent lights and electric motors, a technology that was never intended to power the sophisticated analog and digital circuits used in audio / video systems. Today's premium quality. To adequately accommodate the promise of ever-increasing bandwidth and dynamic range, we must achieve extraordinarily low noise over a very wide range of frequencies.

Additionally, today's power amplifiers are being taxed by instantaneous peak current demand, even when driven at modest volumes. Although we've seen a substantial increase in the dynamics of much of our audio software, the speakers we use to reproduce them are typically no more efficient than they were two or four decades ago. This places great demands on an amplifier's power supply, as well as the AC power supply that supplies it.

The sensitive components of our systems need better alternating current - a fact that has led to a great deal of AC power conditioning, isolation transformer, regenerative amplifier, and battery backup system topologies. Through differential sample testing and spectrum analysis, it can be proven that up to one-third of a high-resolution (low-level) audio signal can be lost, masked, or greatly distorted by the enormous levels of noise circulating through the AC power lines that power our components. This noise is coupled to the signal circuitry as current noise and through the AC ground, permanently distorting and / or masking the source signal.

Since the stakes are so high, all sincere attempts to solve this problem are to be applauded.

Once the audio / video signal disappears, it disappears forever ...

For AudioQuest, honoring the source is never a matter of simply using premium "audiophile quality parts" or relying on proprietary technology - common approaches within our community. For years, we've all witnessed the same seemingly endless audiophile debates: tubes versus transistors; analog versus digital; Can cables really make a difference? and so on. While we too can boast of our many unique technologies, we realize that true audio / video optimization is never a matter of a secret or exotic circuit. When it comes to noise filtering for AC power, many approaches can yield significant results. However, these approaches can also impart hum,

The Niagara 5000 features our patented AC ground noise dissipation system, the industry's widest bandwidth linearized AC filter, and our unique passive / active transient power correction circuitry. With an instantaneous current reservoir of over 90 peak amps, the Niagara 5000 is designed specifically for today's power-depleted power amplifiers. Many AC power products that feature "high current outputs" simply minimize current compression; the Niagara 5000 fixes it.

Although it is easy to promote a certain technology, it is 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 to a single octave, thus leaving adjacent octaves and octave partials vulnerable to noise, resonant peaks, or insufficient noise reduction. Consistency is the key. We should never accept a resolution higher than one octave, only to suffer masking effects half an octave away and timbre artifacts two octaves away. This is the primary criterion for AudioQuest's Low-Z Power noise dissipation system.

The Niagara 5000 represents more than 20 years of extensive research and proven AC power products designed for audiophiles, broadcast engineers, and professional audio applications. Every conceivable detail has been addressed: On the Niagara 5000, you will find optimized directionality of RF cables, break-in capacitor-forming technologies developed by Jet Propulsion Laboratories and NASA, and silver-plated AC input and output contacts. heavy on extremely pure copper, ensuring the strongest possible grip.

A great system is built on a solid foundation, and that foundation begins with energy. With an AudioQuest Niagara 5000, you'll experience for the first time the clarity, dimensionality, frequency spread, dynamic contrast, and grip that your system has always been able to deliver - if only the power had been right!

We invite you to experience the Niagara 5000 and hear first-hand the remarkable results of highly optimized energy management: surprisingly deep silences, impressive dynamic freedom, extraordinary recall of ambient cues, and superb delineation of instruments and musicians. in the space. Once you've experienced it, it can seem so elegant, so logical, and so obvious that you wonder why it hadn't been done before.
