The XTZ Class AP100 is a versatile power amplifier designed to operate in both Class A and Class AB modes, allowing for flexibility based on listening preferences. In Class A mode, it outputs 50 watts, while in Class AB mode, it can deliver up to 110 watts. Users can select the desired mode from the front panel, giving them control over the amp’s sound characteristics. The amplifier is noted for its lively sound and musical appeal, particularly excelling in rendering audio with a full-bodied depth and good tonal balance, though detail may not always reach the highest standards. Its construction features a solid internal steel frame designed to enhance screening between circuits, accompanied by large heatsinks to manage the heat produced during operation. The unit runs hot in Class A mode and still generates significant warmth in Class AB mode, reflecting its robust power management. The amp is also designed with user convenience in mind, offering the option to shut down after a period of inactivity and the capability to bridge for increased power output. Despite some limitations in detailing and weight in deep bass, it competes effectively with various integrated models from brands like Creek and Cambridge Audio.
