TOPPING B100 Mono Pure Power Amplifier

The TOPPING B100 is a mono pure power amplifier that dedicates one amplifier per channel, minimizing crosstalk and interference while maximizing channel separation for true stereo imaging. Built around the innovative T’ang-ku-la Module with a 151dB dynamic range, the B100 delivers 100W into 4Ω with distortion below 0.00007% – clean, consistent power for demanding passive speakers. (Note: two units are required for a stereo system.)

T’ang-ku-la Module – 151dB Dynamic Range

The T’ang-ku-la Module uses a three-stage feedback circuit that drastically reduces circuit noise and high-frequency distortion, delivering an outstanding 151dB dynamic range. Every note, from the faintest whisper to the deepest bass, comes through with stunning clarity and detail.

High Power, Ultra-Low Distortion

The B100 pushes 100W into a 4Ω load or 70-83W into 8Ω while holding THD below 0.00007% at 5W. Punchy, dynamic audio stays clean at any level – no distortion muddying the mix.

Three Gain Adjustments

A front-panel 3-step gain switch (High/Medium/Low) tailors the amplifier’s output to match your speakers and source, with BAL gains of 0dB / 10.4dB / 19.9dB and SE gains of 6dB / 16.4dB / 25.8dB.

Seamless Integration with E70 DACs

The B100 shares design language with the TOPPING E70 and E70 Velvet DACs, connecting via XLR, TRS balanced, or RCA cables for a flexible, cohesive desktop stack.

12V Trigger – Synchronized Power

The 12V trigger input links power on/off with your other devices, letting the B100 wake and sleep in sync with your preamp, DAC, or source for a streamlined system.

Reference-Grade Detail Reproduction

With an SNR and dynamic range of 151dB (balanced), the B100 captures subtle changes in notes with precision, delivering music free from noise, distortion, and coloration.
