SOULNOTE D-1N D/A Converter

SOULNOTE D-1N D/A Converter

Compatible with max. 32-bit/768 kHz PCM and max. 22.6 MHz DSD (DSD512) sound sources
In addition to compatibility with new high-resolution sound sources across a range of PCM and DAD formats from USB inputs, the D-1N also supports coaxial digital inputs (2 systems) and AES/EBU.

The ES9038PRO, ESS’ flagship 32-bit DAC, is installed separately in the left and right channels through a monaural mode that achieves the world’s highest specs (DNR140 dB). SOULNOTE’s original discrete nonnegative feedback amplifier that extends into the MHz region receives up to 120 mA from the powerful DAC current supply and amplifies this power for the output. The combination of the ES9038PRO and the discrete non-NFB amplifier achieves vibrant music playback bursting with energy that cannot be obtained from standard OP amplifier circuits.

Temperature settings
The circuit current in SOULNOTE products relies on solutions with the highest emphasis on sound quality and safety. Functionality and sound quality generally improve when the transistors operate at higher temperature.。
Anti-vibration housing
SOULNOTE products place the highest emphasis on sound quality, so the top cover, chassis, and other components do not employ vibration isolation.
Regarding use of electronic equipment cleaners and contact rejuvenation products on SOULNOTE products
Commercially available electronic equipment cleaners and contact rejuvenation products could damage the resin components of SOULNOTE AC inlets. Do not use these types of chemical products on SOULNOTE equipment.
