Quantum Technology QX4

The Problem

When we listen to music through a hi-fi system or watch a movie on a home theatre, what we are actually hearing and seeing is the power supplies that drive that system, and on an even more fundamental level, the power that is fed to those supplies. It’s a lesson the hi-fi industry has been slow to learn and even slower to deal with. Basic hardware like AC mains cords have only recently made it onto the hi-fi set-up agenda. Yet, the quality of the electricity reaching your system is critical to its performance, with EMF noise and waveform distortion all undermining the performance of those expensive hi-fi components you’ve invested in.

Whilst conventional filters can limit the destructive impact of these problems, they impose their own associated performance costs, raising the source impedance and reducing the peak current capabilities of the AC line. These limitations cause their own readily audible or visible side effects, limiting musical dynamics and robbing images of depth and color.

The Answer

QRT’s proprietary circuitry acts at the source of the problem, reducing EMF noise and RFI interference effects on the mains waveform, audio and video signals – and it does it without limiting the voltage swing or altering the impedance of the AC supply. Which makes the job of your hi-fi’s power supplies and active components much, much easier – and that’s what you hear from your system or see on your screen. Use a QRT purifier and you’ll experience a lower noise floor, greater clarity and separation and increased dynamic range, qualities that are just as apparent (and measurable) when it comes to the color, definition and detail on your AV display as they are in the context of a really great stereo set up. The result? Greater overall musical and visual coherence, more stable perspectives, greater realism.

The Qx4 employs the same high quality machined casework and socket options (15A IEC input, US, Schuko or UK AC output) as the Qx2, but is twice as powerful, containing four QRT field generator modules. Also like the Qx2, it does not limit voltage swing or reduce the impedance of the AC supply.

Qx4 is ideally used either individually to feed a complete system, or in multiple arrays in the most demanding applications. Adding additional units in a carefully considered way will produce even greater Quantum effects, the whole being greater than the sum of the parts.
