Explore Quad Electroacoustic

As of April, 2015 Quad has a new US distributor and we are glad to again be able to get their products. Quad Electroacoustics is one of the oldest audio firms extant and the maker of the famed Quad ESL electrostat, by many considered to be the finest speaker ever made. Quad also makes phenomenal electronics and more conventional speakers. Classic Quad electronics like the early tube amplifiers demand top prices in collector's circles while the Quad "tilt" tone controls are still considered the best ever made. The current crop of products proudly stands on this legacy while incorporating the modern features and styling today's connoisseur demands.

Planar Magnetic headphones
Quad ERA-1 Planar-Magnetic Headphone
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. 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. Sonics are superb for a phone in this price range and reviews all say it outperforms its price.

The Absolute Sound said: "In short, the ERA-1 now stands as one of the finest under $800.00 heasdphjones that money can buy."

Inner Fidelity Product of the year:
"The ERA-1 is an incredibly comfortable, non-fatiguing, huge-sounding, tonal and timbrally pleasing set of headphones with outstanding resolution that breaks the sub-$1,000 USD barrier."

PA One +
Tube Headphone amp with DAC

The PA One + is a highly versatile and user-friendly tube amplifier that has been designed to be the perfect match for any headphone user. Simple
and effective with an amazingly wide variety of digital and analogue sources – balanced, RCA, coaxial, optical, USB; make it easy to listen
to music without ever having to ponder on decoding different formats. It offers exceptional value and sounds great.

In the Innerfidelity review they sum with:
The Quad PA-One+ would be an accomplished headphone amplifier and DAC combo at $800 over the list price. The fact that it comes in under $1,700 USD and that it not only stands alone as a one-stop headphone amp/DAC for both digital and analog input listening duties, but can integrate itself into a larger system thanks to its unbalanced pre-amp outs makes it an even bigger bargain. It is an uncanny translation device for recordings of all types and genres and adroitly conveys the essence, or soul, of a track or album without digital artifice.

S2  3

"Quad has definitely hit the mark with the S2s. They have a smooth, vibrant sound that is refreshingly uncoloured and never less than engaging."

"lntegrating a ribbon with a traditional cone mid/bass is not the easiest of tasks... but the S2 seems to have got it just right."
