Clean. Powerful. Mono. 

Tired of dealing with muddy sound, annoying crosstalk, and amplifiers that can’t handle your power-hungry speakers? Enter the TOPPING B200 Ultra-high performance mono power amplifier. This guy solves all your audio woes with its groundbreaking NFCA discrete amplifier and a hefty 200W output power. As a mono amplifier, the B200 is dedicated to delivering pure, focused sound to each speaker, eliminating interference and capturing every detail. Whether you’re a seasoned audiophile frustrated by subpar equipment or just starting your high-end audio journey, the B200 gives your speakers the power and clarity they deserve. 

Newly-developed NFCA discrete amplifier

This tech wizardry cuts down distortion and noise, letting your music shine in all its glory. With the NFCA circuit, you’ll catch every nuance and detail in your favorite tracks.

Three sets of XLR/TRS balanced inputs

Why settle for one input when you can have three? The B200 comes loaded with three sets of XLR/TRS balanced inputs. This gives you the freedom to hook up all your favorite gear. Got a DAC, a CD player, and a streaming device? Bring 'em all. Balanced inputs are the secret sauce for reducing noise and interference, helping your signal stay squeaky clean. 

200W output power

The B200 doesn’t mess around with its 200W output. This amp’s got the muscle to handle the hungriest of speakers. And with high/low gain options, you can tweak the settings to match your environment and equipment perfectly. 

Exquisite detail reproduction in music

Bring your music to life. With a stellar Dynamic Range (DNR) of 145dB and a Signal-to-Noise Ratio (SNR) of 145dB, this amp captures every little detail. Whether it’s the subtlety of a whispering violin or the power of a NIN song at full tilt, the B200 reproduces every nuance with stunning accuracy. 

Seamless integration with other devices

The B200 includes a 12V trigger input interface, allowing for linked power on/off with other devices. With a single power action, you can control multiple devices.
