Quad are a highly renowned manufacturer of quality hifi electronics and loudspeakers, having developed award-winning audiophile-standard products standard for over 80 years, their highly acclaimed reputation is well-earned. The company originally built speakers for public address, moving onto domestic hifi following the end of the war. The first commercially available products were the Quad 22 Pre-amp and Quad II Monoblock Power Amplifiers, both of which were on the market for ten years to great success. 

Quad now develop a wide range of hifi products at varying price points, such as the S Series, Z SeriesElectrostatic Series of loudspeakers and accompanying amplifier ranges the Vena and QII Series. Quad also build a range of Active Loudspeakers. Quad continue to win the hearts of critics and consumers alike with each release and each product bears the same original design philosophy set out by founder Peter J. Walker; to design and engineer a product that offers 'the most accurate' sound response for the best price. 

Quad's QII (or 'Quad 2') series is based on the original Quad II amplifier, built by the company's founder Peter Walker in 1953, but now seeing the integration of finer components and materials, more intricate yet effective circuit integrations and a more precise manufacturing process. The QII series features some of the most refined sounding valve pre/power combinations on the market today, retaining the genuine heritage and craftsmanship that Quad have preserved over 80 years of designing and engineering quality hifi. 

The Quad II Forty features much of the same elegance and commitment to sound quality that was found with the original Quad II, launched in the 1950s, but sees the implementation of a larger chassis capable of housing the larger hand-wired audiophile components within. Now capable of a higher output, the Quad II Forty is the ideal solution for the discerning analogue music listener. 

The Quad II Forty uses larger output valves and comprises of upgraded tubes from the KT66 to KT88. These quality valves, combined with the robust power supply utilising a 5U4G rectifier valve. The input valves are to military specification 6SH7s, an improvement over the EF86s.
