Mono Power, Pure Performance

The TOPPING B100 Mono Pure Power Amplifier gives you the ability to dedicate one amplifier per channel, reducing crosstalk and interference, and maximizing channel separation for true stereo imaging. (Note: you need two of these for a single stereo system.) This makes the B100 an excellent choice for anyone building or upgrading a high-end stereo system, especially if you're working with large, passive speakers that need clean, consistent power. With its innovative T’ang-ku-la Module, ultra-low distortion, and precision-detail reproduction, the B100 delivers music that’s free from noise, distortion, and coloration. Whether you're setting up a dedicated listening room, refining a home theater, or building a reference-grade audio system, the B11’s pure power and performance will make it the cornerstone of your hi-fi setup.

T’ang-ku-la Module: 151dB dynamic range

The T’ang-ku-la Module is a significant leap forward in amplifier design. It utilizes a three-stage feedback circuit technology, which drastically reduces circuit noise and high-frequency distortion. This leads to an incredible dynamic range of 151 dB. Every note, from the faintest whisper to the most powerful bass drop, comes through with stunning clarity.

High power, low distortion

The B11 delivers powerful sound without compromising on clarity. Even when pushing out 100 watts into a 4-ohm load or 50 watts into an 8-ohm load, it maintains a THD of less than 0.00007%. That means you can enjoy punchy, dynamic audio without worrying about distortion muddying the waters. And with three gain adjustments (High, Medium, Low), you can tailor the amplifier’s output to perfectly match your speakers.

Seamless integration with E70 DACs

The B100 is designed to work in harmony with TOPPING’s E70 and E70 Velvet DACs. Sharing the same design language, these components connect via XLR, TRS balanced cables, or RCA cables, offering you flexibility in your setup. And with the 12V Trigger input, you can link the power on/off function with other devices, streamlining your system and making it easier to enjoy your music.
