This ensures that every transistor is kept at its optimum operating point, minimising nonlinearities due to changes in current and internal thermal effects, and eliminating the objectionable “cross-over” distortion typical of class AB circuits.\u003c\/div\u003e\n\u003cdiv\u003e\n\tDue to the higher steady state (or “quiescent”) currents used, the power dissipation of class A circuits is substantially higher than can in general be handled by integrated circuits. It is also possible to design discrete transistor circuits to operate at higher voltage rails than are available for audio integrated circuits, adding the benefit of greater headroom and improved dynamic range. For these reasons, there are no integrated circuits in the audio paths of the Ebony Series.\u003c\/div\u003e\n\u003cdiv\u003e\n\tThe outstanding audio quality is reflected in the technical
