Quad Q-24 preamp plus 2 x 2-40 power amplifiers in PROSPECT, South Australia for sale

Arguably one of the most important products in the history of hi-fi was the Quad II power amplifier. Now, many decades after the original, the Quad II-forty valve amplifier and the Quad Q-24 preamplifier are available in updated form to delight music lovers everywhere. For many audiophiles, the age of the transistor left a big hole in the emotion and pleasure provided by good valve amplification. The hi-fi world became orientated around numbers and statistics and choosing a new product was simply a question of numerical specifications. Based on the styling of and reflecting Peter Walker's circuit topology from the original, but brought up to date by the remarkable skills of mechanical and electrical engineers, these new versions bring a richness and weight to any recording without the colouration many expect from such amplifiers. Not only are these some of the finest sounding valve pre/power combinations available today, but the genuine heritage and craftsmanship of the original has been preserved in the styling which can only be described as exquisite. The Quad II-forty retains the elegance of the 1950s Quad II but with a level of sophistication, a build quality and finish rarely seen on any product old or new. The chassis has been substantially increased in size to accommodate the much larger components, all of which are hard wired by hand following a similar topology to the original. The modern listener demands a higher output than the fifteen watts of the original Quad II. The new Quad II-forty uses larger output valves, KT88s instead of KT66s, and a more robust power supply utilising a 5U4G rectifier valve. The input valves are now military specification 6SH7s instead of EF86s. All Quad products are expected to last a lifetime, even longer. Many Quad customers still derive immense pleasure listening to products built over fifty years ago. These new amplifiers are no exception and with periodic servicing and a caring hand you can expect the performance of these amplifiers to continue for many decades to come.
