Quiescent amplifiers

” … one of the best amplifiers in the world”– the view of experienced reviewers who heard the development amplifier.

In the production amplifiers you will hear a natural presence and realism of performers in the room. Probably beyond anything you have heard before, anywhere.

Of course there is atmosphere, outstanding purity, rhythm and timing as in the live performance and deep, tuneful under-pinning bass.

Amplifier rear panel, showing switchable RCA and balanced inputs, an LED defeat switch and a grounding terminal. Also available in natural silver.

But it is the close-your-eyes-and-they’re-there realism that pins you to your seat.

The amplifier recovers levels of the finest detail so often lost to the pollution that pervades most systems. Realism is startling.

 

The secret is in Quiescent’s technology, absorbing vibration and RF pollution, that delivers the purest music you’re likely to hear.

These are ground-breaking components, setting new standards of performance. We have one on demonstration.

Why is this amplifier so special?

The science behind the pollution control was developed from experience with installations of electronics in military jet aircraft, exceptionally noisy environments. Recovering the finest possible detail from instruments is obviously crucial in operational conditions. It may seem miles away from replaying music but the requirements are actually very similar – vibration and RF pollution kill crucial information, whether it’s music or a hostile aircraft.

Read more about the fundamental importance of this technology below and throughout this site.

The first product in this revolutionary series was the Quiescent Streamer, available and on demonstration with us. It is astounding. Some listeners have been moved to tears – literally – by the emotional impact of performances never heard before.

Extraordinary care in design

Even the casework is special:

  • cooling tubes milled from the solid, avoiding fins that ring

    Helical scrolls in cooling tubes

    Cooling tubes have helical scrolling to minimise ringing and resonance

  • further resonance control from helical scribing inside the tubes
  • top panel of non-metallic material to prevent circulating magnetic fields
  • rear terminal panels mounted independently from the chassis

Inside the case this amplifier is packed with the technology unique to Quiescent that absorbs vibration and RF interference at the source, in the circuits  before it can spread to degrade performance. Designated “Q Power” the package includes:

  • mains vibration and RF absorption
  • DC blocking
  • vibration absorption attached to the transformer
  • very fast voltage regulation, that allows a
  • bandwidth from 1Hz to 1.5MHz
  • absorption of speaker vibration at the output terminals

HiFi systems are flooded with vibration and electrical “noise” energy that clashes with the music signal and destroys information – permanently.

Draining and absorbing this pollution frees the music signal and allows the system to reveal its potential.

No amount of conventional upgrading, by changing amplifiers, speakers etc, can recover information once it’s destroyed.

Systems create their own vibration, from power supplies and loudspeakers, then it’s carried throughout by the metal cables.

Vibration is created externally, by loudspeakers, traffic and even the planet itself, BUT if you isolateyour equipment from its surroundings you actually trap vibration inside the electronics.

RF pollution on the mains comes from LED lights, household appliances and poor power supplies – eg computers and TVs – and also airborne from mobile, police and TV transmissions. It’s everywhere.
