The Little Dot Zero is a desktop DAC and headphone amplifier whose amplifier stage is powered by a pair of 1K2 tubes. This allows it to produce a sound that is both warm and subtle, emphasizing greater musicality.
The Little Dot Zero also features a digital-to-analog conversion stage, allowing it to offer USB-B input and Bluetooth 5.0 reception, in addition to a 3.5mm jack line-in input. In addition, the Bluetooth chip used supports high-definition data codecs such as aptX HD or LDAC, the latter supporting sampling rates up to 24-bit 96 kHz. Finally, the Little Dot Zero has dual headphone outputs with 3.5mm and 6.35mm jacks.
