Super-A Integrated Amplifier
For years, audiophiles have praised the purity, depth and naturalness of Class-A amplifiers.
But they haven't been wild about the heat, weight, power limitations and high cost that go hand-in-hand with Class-A's low efficiency and high idling currents. That's why Class-A has remained a rare, esoteric design chosen by the few who were willing to pay for its fidelity and put up with its limitations.
JVC Super-A design brings together the purity of Class-A and the efficiency of the more common Class-AB. By eliminating most of the measurable switching and crossover distortion. Super-A achieves the kind of sound that has distinguished Class-A designs of the past.
At the same time, Super-A is as efficient as Class-AB, so there are no heat and weight problems which also drive up the cost of conventional Class-A. and JVC Super-A amplifiers have no transient intermodulation distortion (TI) thanks to very wide bandwidth capabilities. What's more, the A-X2 Zsuper-A amplifier shown here includes a 5-band graphic equalizer for both normal playback and recording EQ. LED power meters, "direct power supply" which yields high damping factor at all frequencies, and JVC's Triple Power protection system.
All this comes with plenty of power behind it; 40 watts per channel continuous (RMS) power into 8 ohms, from 20 to 20,000 Hz, with no more than 0,007% Total Harmonic Distortion:.
