TOPPING VX1 Vertex Class T digital amplifier 24bit/96kHz USB DAC Headphone amplifier

The TOPPING VX1 is a versatile device of a formidable efficiency designed with high quality electronic components.

Based on a Class-T Tripath architecture with a TA2021B chip, this T-amp delivers a precise and dynamic sound, despite its maximum power of approximately 2x25W.
It is enough for moderate volume listening, even on low-efficiency 88 dB speakers.
DAC USB, it incorporates a Phillips UDA1351TS converter, a VT1620A USB interface and an OPA2134 PDO.
