Light Harmonic Launches $20,000 USB DAC


Sacramento, Calif. - High-end audio supplier

Light Harmonic

has begun shipping a $20,000-suggested 384kHz/32-bit USB 2.0 DAC.

The Da Vinci

The 61-pound Da Vinci, which is the company's first product, features two-piece aluminum chassis designed to isolate the power circuitry. The flat, square upper module houses power for all AC-to-DC conversions, control functions, the display, and the clocks, while the square base plate houses the digital and fully balanced analog circuits and a gear-shaped heat sink. The top module rotates so the two modules can sit at 45-degree angles.

 Key features include ability to accept 384kHz/32-bit pulse code modulation (PCM) digital audio without upsampling, automatic LSB (least significant bit) correction to deliver bit-perfect audio, and 3-L buffering to offset speed fluctuations in the source. The device also features three clocks. One clock is for 44.1, 88.2, 176.4 and 352.8kHz sampling frequencies. A second is for  48, 96, 192 and 384kHz sampling frequencies, and a third is for the USB interface. Da Vinci selects each clock automatically according to the sample rate of an input file.

A proprietary Duet Engine uses analog interpolation to double a file's original sampling rate without digital upsampling, over-sampling, or noise shaping to deliver smoother high frequencies.
