無 Nothing in the way
Everyone adds.
Soulnote subtracts.
The best producers know the secret: the art is what you leave out. Soulnote engineers the same way — every stage a conventional design adds to the signal path is a chance to blur the original waveform, so Soulnote removes them, one by one, and tunes what remains by ear.
Between input and output: 3 extra stages, each with a fingerprint. Between input and output: almost nothing.
Every stage does a job — and leaves a fingerprint on the waveform as it passes through.
Fewer hands on the signal. What remains was chosen by listening — part by part.

About the Soulnote D1N Performance DAC
Flagship DAC Genes, One Box: Soulnote D1N Performance DAC
The Soulnote D1N Performance DAC brings Soulnote's completely non-NFB digital philosophy to a single-box converter — and it doesn't hold back. Built around ESS's flagship ES9038PRO 32-bit DAC in monaural mode, it hits world-class figures (140 dB dynamic range) and supports every high-resolution format you can throw at it, up to 32-bit/768 kHz PCM and 22.6 MHz DSD (DSD512). Hand-built in Japan by ex-Marantz engineer Norinaga Nakazawa's team, it makes digital sound vivid and alive.
Non-NFB, Straight From the Current Source
Where most DACs lean on op-amp output stages, the D1N uses Soulnote's original discrete non-NFB amplifier, operating up into the MHz region and taking up to 120 mA directly from the DAC's powerful current output. The result is energy-filled, dynamic playback that conventional op-amp circuits simply can't match — the immediacy that defines the Soulnote sound.
Connect Everything
USB, twin coaxial (S/PDIF) and AES/EBU inputs cover every digital source, feeding balanced XLR (5.6 Vrms) and single-ended RCA (2.8 Vrms) outputs. Whether it's a streamer, a computer or a CD transport, the D1N gives it a first-class conversion.

Frequently Asked Questions
What resolutions does the D1N support?
Up to 32-bit/768 kHz PCM and 22.6 MHz DSD (DSD512) over USB, plus PCM to 192 kHz over its coaxial and AES/EBU inputs — covering virtually any hi-res source.
Why is a non-NFB, discrete output stage a big deal?
It avoids the negative feedback and op-amps most DACs rely on, taking current directly from the DAC chip for a faster, more dynamic and lifelike sound — the hallmark of Soulnote's design.
What inputs does it have?
USB Type-B, two coaxial S/PDIF, and AES/EBU.
