Topping g B100 Monoblock Amplifier

Mono power, pure performance: Whether you're setting up a dedicated listening room, refining a home theater, or building a reference audio system, the TOPPING B100 pure mono power amplifier lets you dedicate one amplifier per channel, reducing crosstalk and interference while maximizing channel separation for a true stereo image.

Advanced T'ang-ku-la Module
Features a three-stage feedback circuit that minimizes noise and distortion while achieving an exceptional dynamic range of up to 151 dB. This design enhances both reliability and long-term durability.

Exceptional Audio Clarity
With an SNR and DNR reaching 151 dB, the B100 reproduces every musical detail with remarkable precision, maintaining ultra-low noise levels below 0.3 µVrms (G=L).

Ultra-Low Distortion
A THD+N of less than 0.00008% ensures accurate, true-to-life sound reproduction, preserving subtle nuances for a deeply immersive listening experience in both mono and stereo configurations.

Powerful & Precise Output
Maintains extremely low distortion across all output levels, with THD under 0.00007% at 5W (4Ω/8Ω). Includes three selectable gain settings for optimal system matching.

Seamless System Integration
Easily integrates with E70 and E70 Velvet DACs via XLR, TRS, or RCA connections, forming a cohesive and high-performance audio system.

12V Trigger for Simplified Control
Equipped with a 12V trigger input for synchronized power control, allowing convenient one-touch operation across your entire setup.
