The DA-150 is a state of the art, compact, USB D/A converter built upon the same principle as its predecessor, the DA-100, that is to construct a simple PC audio environment to offer high-quality sound in a small footprint. Desktop usability and high sound quality co-exist perfectly within the design of the DA-150 with features such as compatibility with USBs inputting PCM 192 kHz/32 bits and DSD 5.64 MHz (like the upper model DA-250), a headphone amplifier circuit with remarkably improved drive force and the addition of the LECUA* computerized attenuator as standard. As a digital interface to connect with various devices to reproduce high-resolution sound sources, the DA-150 raises the benchmark for compact D/A converters. *LECUA is an abbreviation of Luxman Electric Controlled Ultimate Attenuator. * LUXMAN Audio player (corresponding to Windows 10 / Mac OSX v10/11) and driver software for Windows can be downloaded from LUXMAN homepage.
