exaSound e20 Mk II is the first high-end DAC capable of achieving DSD playback at sampling rate of 11.2896 MHz (DSD 256). e20 Mk III sets another first - support for DSD at 12.288 MHz. In addition to offering the highest digital audio resolution, the e20 DAC has jitter, distortion and noise levels that are vanishingly low, creating an astonishingly clean and analog-like sound – the difference is obvious, even with an ordinary CD.
e20 DAC Features
◾e20 Mk II: DSD 2.82MHz, DSD 5.64MHz (DSD 128 Fs), DSD 11.28MHz (DSD 256 Fs).
◾e20 Mk III supports three additional sampling rates: DSD 3.072MHz, DSD 6.144MHz and DSD 12.288MHz.
◾384kHz/32bit maximum PCM sampling rate. Native support for DXD 352.8kHz master files.
◾ES9018 Sabre32 reference DAC chip from ESS Technologies.
◾Asynchronous USB Interface eliminates jitter caused by unstable computer timing.
◾OS X and Windows ASIO custom high-performance drivers. (DSD256 is supported only on Windows)
◾Automatic sampling rate switching.
◾384 kHz software upsampling.
◾0.13 ps master clock. Jitter minimization is achieved by using 3 three precision oscillators.
◾11 power filtering stages.
◾Galvanic isolation between the USB subsystem and the DAC circuits eliminates ground loops noise and blocks computer-originated interferences.
◾Second generation headphone amplifier that can bring the best out of the most accurate headphones.
◾Simultaneously driven, gold plated balanced (XLR), and unbalanced (RCA) line outputs.
◾Two S/PDIF inputs provide jitter reduction and superb D/A conversion when used with CD transports.
◾The e20 DAC can be programmed to work with most IR remote controls.
