Quad II Integrated 

Quad 2805’s are the speaker that most reviewers use as a cornerstone of sound around which they gauge the success or failure of many other products.  You owe it to yourself to make a trip to Wellington Audio and hear what they are talking about.

Hi Res 2805 pair

Quad 2905 - This the best electrostatic Quad is capable of making.  It has more dynamics and volume capability than the 2805 and should be thought of as a personal speaker capable of unlimited speed, resolution, and transparency capable of giving you an incredible “window on the performance”.  Matched with the right electronics, this should satisfy music lovers for many years.

Quad II-classic

15W Valve mono power amplifier


The new Quad II-classic offers audiophiles the chance to recreate the spirit and atmosphere produced from one of the most famous amplifiers in audio history. The original Quad II was first launched in 1953, designed by Peter Walker. The Quad II looked very simple and unassuming, but its performance was far beyond that which its dimensions might suggest. The property which set the Quad II amplifier apart from other amplifiers of the time was its output stage. It was arranged such that the cathode coupled circuit emulated the performance of triode operation, but with the size and efficiency characteristics of pentode operation. It was this breakthrough that ensured the Quad II was to remain in continuous production until 1970. Peter’s circuit, notably the design of the output transformer, has become the stuff of legend amongst electronics engineers. Studied and analyzed by the finest minds in the industry, the elegance and coherence of the design is still regarded as a reference today.

The Quad II-Classic has been recreated accurately with output valves and input valves the equivalent of those used in the original design. The same balancing act has been employed to ensure the same wealth of detail and gentle tone of the original. The output valves produce around 15watts per channel, operating in Class A which, although slight by modern standards, allows a gloriously sweet and refined sound with appropriately matched contemporary loudspeakers.
