Topping TP30-MARK2
Topping TP30-MARK2

Class-T Digital Amp, USB DAC & Headphone Amp in One

Named one of the 10 best headphone amplifiers in the game by Equipboard, the Topping TP30-MARK2 is that and more. A class-T digital amplifier with both a built-in USB DAC and a headphone amplifier, this versatile, compact unit is ideal for desktop setups with passive bookshelf speakers. It’s an update on the TP30, which High-Fidelity Review calls “one punchy amp” whose “value per dollar in construction, parts, and sound quality makes for an easy buy.” This new version has many of the same specs—same handsome aluminum chassis, same Tripath TA2024 digital amp, same high-quality electronic components—this time with full Android support. A domed ALPS volume control completes the package, with a blue LED ring that indicates when the power is on.
