Pure A/B Class Advantages & Benefits:

Regulated power supplies, stabilize voltage drops common in automotive electrical systems to prevent voltage-drop induced distortions.

Low-idle current demands lower operating temperatures and that lowers Noise, THD levels and improves voltage rail tracking and fidelity.

Balanced circuit’s require precision tolerance electrical components and is the basis for MB Quart’s “Pure A/B Class” designation.

Ultra wide-band frequency response of 10Hz to 30,000Hz is well beyond any human’s hearing range, which insures absolute audio accuracy even for a person with perfect hearing. Pure A/B Class improves musical focus, imaging and dynamic range.

Power symmetry and extreme linearity prevents the loudspeaker’s ever fluxuating impedance from affecting the amplifier’s power output so that the music sounds more lifelike.
