The Quad Valve Amplifiers

Although good valve amplifiers come and go, none are as timeless, elegant or loved as the Quad II. The first Quad IIs were originally produced in 1952 and todays models use the same exquisite circuit topology that made Quad so famous all those decades ago.

II-forty - Now with 40wRMS output per monobloc from a brace of KT-88s, the new II-forty offers all the subtlety and richness usually associated with the finest high-end vacuum tubes, but with enough power and speed to drive modern loudspeakers, especially those that present a difficult load. The input and rectifier tubes are extremely accurate military specification valves with quite exceptional longevity.

The system as a whole includes an equally beautiful pre-amplifier and two power amplifiers with twin output speaker taps at 4ohms and 8ohms.

II-Classic - The new Quad II-Classic is a faithful reproduction of the original. Using KT66 output valves, the full richness and presence of the original valves is back in all its glory.
