M1DAC is a stereo digital-to-analog converter (DAC) known for its performance and features. It utilizes a 24-bit Delta-Sigma (big-stream) circuit with 8x oversampling to 192kHz, offering a frequency response of 10Hz to 20,000Hz (-0.1dB max) and a signal-to-noise ratio of >119dB "A"-weighted. Here's a more detailed look at its specifications: Key Features and Specifications: Circuit: 24-bit Delta-Sigma (big-stream) dual differential 8x over-sampling to 192kHz. Jitter: Total Correlated Jitter: <12 picoseconds peak-to-peak. Linearity: <0.1dB down to -96dB. Frequency Response: 10Hz to 20,000Hz (-0.1dB max). Channel Separation: >105dB @ 20Hz-20kHz. Signal-to-Noise Ratio: >119dB "A"-weighted. Total Harmonic Distortion: <0.0025% @10Hz-20kHz. Inputs: 1x XLR AES balanced digital input. 1x RCA coaxial connector SPDIF 32-192 kbps (16-24 bit stereo PCM). 1x TOSLINK optical connector 32-96 kbps (16-24 bit stereo PCM). 1x USB type 'B' connector for computer/PDA - 16-24 bits, 32-96 kbps. Outputs: Stereo balanced (XLR) and RCA. Power Supply: High-quality with choke filtration on the mains input. Additional Notes: The M1DAC can upsample any material to 24-bit/192kHz, though USB is limited to 24-bit/96kHz. It is designed to work with a variety of digital audio formats and sources, including CD data, 96kHz data, and high-resolution files. The M1DAC is known for its clear, open soundstage and excellent performance, with low distortion and excellent channel separation according to a What Hi-Fi? review.
