Noise-Dissipation Systems.


Enhancing the in-home experience.

For some, a power conditioner is merely a device that provides enough outlets for the entire audio/video system while also protecting the connected devices from electrical storms and wiring faults. Yet, for the discriminating listener, many power conditioners can make an audio/video system perform far worse. That's where AudioQuest comes in.

AudioQuest Niagara Series

Unlock Your System’s True Potential

The products in AudioQuest’s Niagara Series are meticulously handcrafted, and their technologies are unique amongst all power products—whether they’re isolation transformers, AC regenerators, battery backup devices, re-clocking devices, or other types. Far surpassing most other technologies that cover only a narrow range of noise frequencies and do nothing to address the increasingly prevalent noise on AC ground, Niagara’s Level-X and patented Ground-Noise Dissipation (GND) Technology work evenly, or linearly, across a far wider range of induced noise frequencies.

Additionally, Niagaras 3000, 5000, and 7000 feature Transient Power Correction, which supplies a current reservoir to greatly bolster the performance of any power amplifier.

With an AudioQuest Niagara Low-Z Power Noise-Dissipation System, music lovers can finally experience the clarity, dimensionality, frequency extension, dynamic contrast, and grip their A/V systems have been capable of delivering—if only the power had been right!

  • AudioQuest Niagara 7000 - $11,000
  • AudioQuest Niagara 5000 - $5,900
  • AudioQuest Niagara 3000 - $3,900
  • AudioQuest Niagara 1200 - $1,595

AudioQuest PowerQuest Series

All three of AudioQuest's new rack-mountable PowerQuest models — the PQ-303, PQ-505, and PQ-707 — take AudioQuest's comprehensive approach to AC power conditioning, addressing noise linearly to provide class-leading, wide-bandwidth noise reduction (better than -22dB).

The PQ-303’s Linear Noise-Dissipation comprises Differential-Mode filtering (30kHz–1GHz), which addresses asymmetrical noise already present on the utility line or backwashed via electronic appliances and components. In the PQ-505, Ultra-Linear Noise-Dissipation is achieved with the addition of Common-Mode filtering (30kHz–100MHz) to address symmetrical noise, which is typically picked up by the AC Line, Neutral, and Ground leads. In the PQ-707, Ultra-Linear Noise Dissipation is taken even further with a wider-bandwidth (8kHz to 1GHz) Differential-Mode filter.
