Musician Audio has introduced the Delphinus, a true R-2R ladder DAC positioned as an entry point into the Chinese brand’s decoding lineup without cutting corners on the resistor network that defines its sound. The Musician Delphinus R2R DAC is compact enough to sit comfortably on a desk, sideboard, or living-room shelf, and its brushed metal fascia and machined feet are designed to look at home in a variety of listening spaces. Where Musician’s higher-tier models use machined aluminum enclosures, the Delphinus R2R DAC houses the same core decoding architecture in a more cost-efficient iron chassis, letting the company hold the line on price while keeping the parts that matter most to sound quality intact.
At the heart of the Musician Delphinus R2R DAC is a true R-2R resistor ladder built from high-precision resistors rated to 0.005 percent tolerance, avoiding the delta-sigma modulation and heavy digital filtering used in most modern DAC chips. Musician pairs that ladder with a DSD-capable architecture, so the Delphinus R2R DAC decodes both PCM and DSD natively rather than converting one format into the other. Over USB and I2S, the deck accepts PCM up to 1536kHz and DSD up to DSD1024, while its coaxial, optical, and AES inputs handle PCM up to 24-bit/192kHz and DSD64 via DoP. Eight selectable I2S pin-out modes broaden compatibility with third-party transports and streamers.
Connectivity and controls
The Musician Delphinus R2R DAC offers five digital inputs: USB, I2S, coaxial, optical, and AES, alongside a set of front-panel controls covering phase inversion, fast/slow filtering, left/right channel swap for DSD playback over I2S, and a switchable NOS/oversampling sampling mode. Analog output comes via a single set of XLR and a single set of RCA jacks, rated at 4Vrms and 2.0Vrms respectively; Musician notes the balanced XLR output delivers the DAC’s best performance and advises against running both outputs simultaneously. A bundled remote control handles power, input selection, and the same front-panel functions from a distance, though it ships without its CR2032 battery due to air-freight regulations, and Musician recommends a 2mm Allen wrench to open the compartment and fit one before first use.
Build and measured performance
Power comes from an 80-watt toroidal transformer housed in its own shielded metal enclosure to isolate the R2R ladder from noise and current fluctuations, backed by carefully selected capacitors and an SMD crystal oscillator for clock stability. Musician rates the Delphinus R2R DAC at under 0.002 percent distortion (A-weighted), signal-to-noise of 120dB or better, dynamic range above 121dB, and stereo crosstalk above 110dB, with a frequency response of 20Hz to 75kHz. Musician recommends up to 300 hours of burn-in, either powered on continuously or left in standby, before the Delphinus R2R DAC reaches its full performance.
Pricing and availability
Musician Audio has not published direct retail pricing for the Delphinus R2R DAC on its own site, instead directing buyers to its Amazon storefront, its official online mall, and AliExpress; interested buyers should check current listings or a regional distributor for exact pricing in their market.
