## Long description

The InLine AmpUSB 384KHz/32bit DSD USB Audio DAC with Vacuum Tube amplifier is a high-resolution USB DAC and integrated tube headphone amplifier designed to bypass a computer's internal soundcard and provide improved digital-to-analog conversion. It supports PCM up to 384 kHz and DSD up to 128× DSD, connects to playback devices via a 3.5 mm headphone output, is powered via USB, and has compact desktop-friendly dimensions (81 × 110 × 80 mm). The unit produces a warm, quasi-analog character through its amplifier tube while offering a measured signal-to-noise ratio of 110 dB.
Advantages
The device converts high-resolution PCM and DSD audio via USB, enabling playback up to 32-bit/384 kHz and DSD128, and bypasses the computer's soundcard for cleaner output. The vacuum tube stage imparts a softer, more natural tonal character to the signal while the DAC section handles precise digital-to-analog conversion. Its USB power and compact size make it convenient for desktop use, and compatibility with Mac OS X (10.6–10.9) ensures straightforward installation on supported systems.
