■ HRT (High Resolution Technologies) Interface ■ Designed and manufactured entirely in Southern California by a group of up-and-coming engineers. ■ Further upgraded from the "Music Streamer II," featuring a more high-performance DAC chip. The analog circuit design has also been revised, enabling higher-quality digital/analog conversion, with an improved S/N ratio from the previous model's 99dB to 115dB. ■ USB input supports 96kHz/24bit. ■ Built-in proprietary special circuits designed to reduce power supply noise. ■ Power and signal isolation to reduce noise. ■ Asynchronous circuit eliminates jitter. ■ All design and manufacturing done in California, USA. ■ Convenient portability with USB bus power, eliminating the need for an AC power supply. ▼ Specifications ■ Maximum Output: 2.25V ■ Frequency Response (20Hz～20kHz): 0dB/-0.4dB ■ Noise Floor (DC～30kHz and above): 4μV ■ S/N Ratio (DC～30kHz and above): 115dB ■ Sampling Frequency: 32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz ■ Quantization Bit Depth: 24bit ■ Power Consumption: 250mA ■ Dimensions: 142.5mm x 58.5mm x 22.3mm ■ Supported OS: Windows XP, Vista, 7 (Windows 7 recommended), Mac OS ■ USB 1.1, USB 2.0 compatible
