Experience Music As It Is Supposed To Be

elemento-gráfico-pagina-blog

Our T100 monoblock power amplifiers are now on demonstration at KJ WEST ONE.

After a 3-year research programme, we were granted our patent in November 2023. Our T100 power amplifiers use this patented technology in key areas to reduce vibration transmission into critical circuits and prevent standing waves from being generated along circuit paths, cables, and wiring looms inside the electronics. So why are the T100 series power amplifiers different, and what is new about them? The answer is that we do not seek to refine existing amplifier topology but to revolutionise it. No other manufacturer pays attention to the micro-energy that is being cascaded around the electronics, and only Quiescent has the technology to solve the problem of that very last level of noise present in systems, removing it from the signal without compromising the quality of the music. The result is amplifiers so quiet you don’t even know they are there. It sounds like an oxymoron until you hear what they do.

To experience the award-winning T100 monoblock and stereo amplifiers offering a seismic leap in an immersive audio experience, go to KJ West One and discover what truly lies in the recording. But we should let you know that the experience, once heard, cannot be unheard.

The T100 power amplifiers are not just an upgrade; they challenge all conventional thinking and redefine how a power amplifier should be.

We are thrilled to announce that MBS Audio is now demonstrating Quiescent products.

MBS Audio is an audio retailer with a refreshing approach. They have decided to concentrate on helping customers get more performance from the already significant investments that they have made in their audio systems.

Having tested our products against other similar solutions, the team at MBS Audio felt that Quiescent and its relentless pursuit of eradicating noise generated by EMI/RFI and vibration is the best choice for its customers. We are pleased that their thorough evaluation has concluded that Quiescent is the only manufacturer that truly understands the physics behind these damaging forces leading to products that make a profound and instinctively right upgrade without changing core components.

We are thrilled to work with MBS Audio to help customers get more value from their audio.

Quiescent Apex Couplers

Review by George Sallit

I have to admit I was surprised by what was happening as all that I did was put three (passive?) feet under each piece of audio on an already decent isolation rack. The sound improved and I was imagining I was there, in the Tonhalle in Zurich.

Meet Your Maker

Nigel Payne of Quiescent

Quiescent might not be a name that trips off the tongue just yet, but bear with us; the company took the original concepts of Vertex AQ and has developed them for the 2020s. We spoke to Nigel Payne of Quiescent about the science involved, R&D, and how to extract the most from any good audio system.

AS: Quiescent means ‘tranquillity at rest.’ Was the name deliberate or a Freudian slip?
NP: When we design systems, our fundamental principle is that all components are not at rest. Each active or passive device in a circuit, whether it is a transformer or speaker driver unit, output transistors, capacitors or even microprocessors, actively adds to the musical signal. Our goal is to ensure that the system is invisible to the listener, and our decision to name ourselves Quiescent was a deliberate consequence of that design philosophy.

You are a comparatively new company. What was the motivation for starting Quiescent?
Quiescent was founded in 2017, but our roots go back to the founding of Vertex AQ almost 21 years ago. We felt that Vertex AQ had run its course and opted to form a new company that leveraged our knowledge of electronics and mechanics combined with state-of-the-art computer-aided design and manufacturing techniques. In creating Quiescent, we have established a brand recognised for technology leadership, world-class products and an innovative
approach to radically improving the audio experience.

What are your scientific, technological or audiophile backgrounds?
I began my career studying particle physics and electronics at Leeds University back in the late-1980s. That led me to model noise and vibration, work on high-frequency systems, and program low-level code processors. I’ve taken this experience and applied much of what I’ve learned to my obsession with audio reproduction…

Alan Sircom reviews our Quiescent Peak power modules

elemento-gráfico-pagina-blog

Keen-eyed regular readers might be doing a bit of head-scratching here, as we reviewed both Apex and Peak from Quiescent back in Issue 197. And they’d be right… and wrong. Although the names – and the physical appearance – are the same, what’s in the boxes is geared toward a very different role in your audio system. Where the last round of Peak modules was geared toward being used with loudspeakers (they had speaker terminals and flying loudspeaker leads), these Peaks are all power-based.

There’s a lot to unpack here, figuratively and literally. Starting with the literal; four cartons, containing twelve boxes in total, making six individual devices, made up of eighteen separate components. That’s a lot of stuff to get through. What we ended up with was two sets of the single power feed Peak Mains Module, one dual-output Peak Mains Module, a single Peak Mains Shunt filter, four silver-plated copper Peak UK power cords and four silver-plated copper Peak Neutrik powerCON to IEC connector cables… and
two sets of three of the latest iteration of Quiescent’s Apex40 component couplers.

Figuratively speaking, you need to think of these products as energy control devices, irrespective of whether that energy is electromagnetic, radio-frequency or mechanical. What Quiescent does in every product it makes is to try to tame that wayward energy, using a common set of methodologies for consistency. All feature non-parallel boxes with an acoustically disruptive pattern milled into the heavy black case; an anodised aluminium case for the Peaks, a 3D-printed enclosure for the Apex modules.
