Topping Pre Series B100 Class AB Power Amplifier, Silver Overview
The Topping Pre Series B100 Class AB Power Amplifier is a mono amp built for high-fidelity systems, featuring the T'ang-ku-la Module which uses a brand-new three-stage feedback circuit to minimise distortion and enhance dynamic range to 151dB. This makes it a strong choice for powering premium passive speakers. It is capable of delivering 100W at four-ohms and 83W at eight, ensuring dependable performance across different speaker loads.
For connectivity, the B100 features a combo XLR/TRS input alongside an RCA input, making it easy to pair with a wide range of preamps and DACs. It also features a 12V trigger input, meaning seamless power syncing with a second B100 and connected pre-amp equipment, adding convenience to your system. High-quality speaker terminals ensure a secure connection, while three selectable gain settings (low, medium, and high) let you fine-tune the output to suit your setup.
