Quad’s first-ever headphones use planar magnetic technology to deliver a fast, open and natural sound in keeping with the sonic heritage of Britain’s original high-end audio company. Quad has been responsible for many landmark Hi-Fi products throughout its history, none more famous than successive generations of the ESL – the world’s most revered electrostatic panel loudspeaker, a technology invented by Quad’s founder, Peter Walker.
To create the ERA-1 – the company’s first-ever headphones – Quad developed a planar magnetic driver delivering a fast, open and transparent performance. According to the press release, the resulting sonic realism and fidelity to the source is fully in keeping with the brand’s heritage, displaying qualities akin to the famous ESLs. Most headphones use dynamic cone drivers, but Quad’s planar magnetic technology features an ultra-thin, electrically active diaphragm – thinner than a human hair yet extremely strong and highly elastic, weighing less than the volume of air it displaces. This approach, the company says, delivers a more natural and accurate sound, ensuring the listener hears every nuance of a recorded musical performance.
The diaphragm is driven by a precisely arranged magnet system, designed to maximize sensitivity and consistency of the applied force over the driver area. According to the details published, a patented nonlinear vibration suppression technology allows the driver’s effortlessly extended frequency response to be heard unsullied, ensuring supreme clarity. The metal cavity behind the driver is specially designed for optimal acoustic performance, and the drivers themselves are closely matched to ensure spacious, three-dimensional stereo imaging. Quad says that planar magnetic driver has much better phase coherency, since all parts of the diaphragm are vibrating in concert without break up and delayed resonance. The driver’s flat conductor pattern, with an absence of inductive components, eliminates inductance-related intermodulation distortion.
Many planar magnetic headphones require high-power amplifiers to drive them. The Quad ERA-1 combines high sensitivity with low impedance to enable excellent performance with a wide range of partnering devices, from portable audio players to high-end headphone amps. Obviously, Quad’s valve-based PA-One headphone amp/DAC makes a superb match for the ERA-1.
The headphones feature a premium finish and deliver a suitably luxurious feel, yet the headphones are comfortably lightweight compared to many planar magnetic designs, Quad says. Two types of ear cushion are provided – one made of soft leather, the other of latex topped with a fleecy fabric – enabling a degree of personal tailoring according to the preferred feel and differing acoustic properties of the materials. A high-quality, detachable 215cm cable is also supplied, together with a durable carrying case.
The Quad ERA-1 headphones will be available from late July, with an RRP of £599.95 inc. VAT in the UK market.
