Topping TP31

Topping amplifiers are designed and built using only the best components to achieve the highest level of sound quality possible. Gold plated miniature 5-way binding posts offer many connection options and are insulated to protect against shorting conditions. Inside you will find an ALPS potentiometer, TOKO inductors, Siemans, Panasonic, and Nichicon capacitors, and KOA resistors, and a Panasonic power relay.

Digital to analog conversion is handled by a Cirrus Logic CS8416 digital audio receiver—capable of handling sample rates of up to 192 kHz with low jitter clock recovery—and a Texas Instruments PCM1793 DAC that features 113 dB of dynamic range, less than 0.001% total harmonic distortion and noise, 8x oversampling, and can decode 16 to 24-bit signals. Converted signal is sent to a Burr-Brown OPA2134 SoundPlus op amp for gain to be fed into the amplifier stage.

Amplification is handled by the tried-and-true Tripath TA2024B that creates up to 15 watts per channel of power. Hallmarks of the TA2024B include audiophile-grade dynamic range of up to 98 dB, low distortion, and signal fidelity equal to that of high quality linear amplifiers—at a fraction of their weight and size!

Headphone amplification is provided for critical listening, delivering up to 100 mW into a 32-ohm load with 0.01% total harmonic distortion and noise, and makes the Topping TP31 perfect for use at home or in the studio. World-compatible switching power supply included.

Features: • Digital coaxial input with Cirrus Logic digital receiver and Texas Instruments DAC • 3.5 mm headphone output and gold plated inputs • Separate input and output control switches • Extruded aluminum chassis with CNC-cut volume control, backplate, and faceplate • World-compatible switching power supply included • Miniature gold plated 5-way insulated binding posts • Speaker protection built-in.
