    DAC 3.7 Features

    HDR Core is the result of 20+ years of engineering to refine the digital to analog process, and is comprised of 3 major components: Low Noise and Ultra Low Noise Master Clocks, Advanced Asynchronous Interfaces, and Dual Mode Low-Noise High Efficiency Power Supplies. HDR Core technology is fundamental to every e.One DAC and Integrated product, creating the most realistic, open, and defined musical experience possible.

    VBL logo

    The VBL1 power system lowers the broad band noise floor, reduces AC power noise and improves the overall musicality of the DAC3.7. The VBL1 uses new linear regulator technology combined with a high isolation power transformer to deliver a focused, optimized single 12V output. This critical power stage allows the DAC3.7 to perform at its best with increased sonic resolution, low level dynamics, spatial information, harmonics and timbre.
