The Little Dot DAC_II combines our Little Dot DAC_I's D/A circuit with a built-in (LME49710HA pre-stage and discrete BD139/BD140 transistor output stage) headphone amplifier module! Four inputs (Coaxial, BNC, Optical, and USB) allows the Little Dot DAC_II to be used with digital source like a CD Transport or a computer as a standard USB audio device. User functionality customizations include setting the bit-rate, maximum sampling frequency, and how the DAC's digital filter operate (sharp or gentle). At the heart of the Little Dot DAC_II are the Wolfson Micro's high quality 24-bit 192Khz WM8740 DAC chip, WM8805 ultra-low jitter (50ps) digital transceiver chip, and the ultra-low distortion LM4562/LME49720/LME4910. A dual crystallizer re-clock circuit ensures a synchronized and jitter-free signal!

The internal components have been carefully chosen for their quality and precision - tight tolerance resistors, WIMA coupling caps, ELNA and NISSEI filter caps, Toshiba optical connectors, and BD139/BD140 transistors.

Precise with flat frequency response, the Little Dot DAC_II delivers a smooth and highly accurate sonic presentation with no detail left obscured!
