Topping MX3 is a true multitasker. Its compact, aluminum case is filled to the brim with hi-fi audio components. Inside you’ll find a USB DAC, Bluetooth receiver, integrated amplifier and a headphone amplifier. MX3 is fitted with a myriad of inputs and outputs, including USB, optical and coaxial inputs, and 3.5mm jack headphone output, banana outputs and a dedicated RCA output for a subwoofer.
MX3 is based on high-quality components with proven reputation in the audio world, these include PCM5120A DAC chip, SA9023A USB interface, CS8416 S/PDIF receiver, NJW1194 volume controller, TDA7498E amplifier chip and LMH6643 headphone amplifier chip.
Texas Instruments PCM5120A DAC chip uses the latest generation of TI-s advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. It comes with a 32bit, 384kHz PCM interface and features market-leading low out-of-band noise, integrated negative charge pump, intelligent muting system and an integrated high-performance audio PLL which reduces the system’s EMI.
STMicroelectronics TDA7498E is a dual BTL class-D audio amplifier known for its high efficiency, differential inputs that minimize common-mode noise, small offset and smart thermal overload protection.
Texas Instruments LMH6643 chip responsible for headphone amplification is a true single supply voltage feedback amplifier that offers high speed (130MHz), low distortion (-62dBc), and an exceptionally high output current (approximately 75 mA). Its output voltage range allows for a wide dynamic range, its output stage is capable of driving heavy loads, while fast output Slew Rate (130V/us) ensures large peak-to-peak output swings even at high speeds. Careful attention has been paid to ensure LMH6643’s stability under all operating voltages and modes. The result is a very well behaved frequency response characteristic (0.1dB gain flatness up the 12 MHz under 150 Ω load and AV = +2) with minimal peaking (typically 2dB maximum).
Its intuitive design makes it very easy to use. It has a very readable LED display and a number of features, such as remote control or NFC pairing, those combined with high quality components, guarantees joy of listening to the music.
