This fully discrete 26-bit R2R DAC delivers exceptional digital-to-analog conversion with upgraded network streaming, Bluetooth 5.1, and a refined power supply design. Supporting native DSD512 and PCM up to 768kHz, the R26 II is engineered for audiophiles who demand natural, musical sound – the organic signature that only true R2R architecture can provide.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e26-Bit Fully Discrete R2R Architecture\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt the heart of the R26 II lies a 26-bit fully discrete R-2R resistor ladder derived from the flagship R30 – four times the resolution of the original R26. Unlike delta-sigma converters, the R-2R ladder performs direct, instantaneous conversion of digital signals to analog, eliminating digital harshness and filtering artifacts for a clean, natural, and richly musical presentation with a dynamic range exceeding 130dB.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNative 1-Bit DSD \u0026amp; Hi-Res PCM Processing\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA dedicated DSD processor handles true 1-bit DSD signals with full precision, bypassing PCM transcoding for a pure signal path. Native DSD64–DSD512 is supported via USB and LAN, with staggering DSD2048 available through the I²S interface. PCM support reaches 32-bit\/768kHz, and extends to 32-bit\/1536kHz over I²S – compatibility with virtually any high-resolution source.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAll-New Network Streaming Bridge\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDeveloped in collaboration with CelAudio, the upgraded network bridge runs an optimized Linux kernel for stable, prioritized streaming. It supports Roon Bridge, AirPlay, UPnP\/DLNA, Spotify Connect, and HQPlayer NAA, letting the R26 II act as a dedicated high-end streaming DAC with the amplifier placed right next to your speakers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGCLK-02 Precision Clock Architecture\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe R26 II uses GUSTARD’s Femto Clock Technology with the GCLK-02 module, achieving PLL locking accuracy within 1Hz and ultra-low jitter across all digital interfaces. A dedicated 10MHz BNC clock input accepts an external master clock (50Ω, CMOS square wave or sine) for systems where clock control is handled at a higher level.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual Toroidal Transformers for Clean Power\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDual independent toroidal transformers provide dedicated power to the digital and analog sections, isolating the D\/A conversion process from electromagnetic interference and crosstalk. Paired with upgraded low-ESR premium capacitors and multi-layer filtering, the result is a blacker background where even the quietest musical details emerge with ease.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eClass-A Discrete Analog Stage\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe fully discrete Class-A analog output stage features a Class-A low-pass filter with zero op-amps in the signal path, ensuring pure, natural tone with a rich, organic character. Balanced XLR and single-ended RCA outputs integrate seamlessly with amplifiers, preamps, and active speakers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBluetooth 5.1 with LDAC\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBluetooth 5.1 provides convenient wireless playback with LDAC support for transmission up to 96kHz, along with AAC, SBC, aptX, aptX LL, and aptX HD – easy high-quality listening from phones and tablets without additional hardware.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eComprehensive Inputs \u0026amp; Outputs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA wide input array covers USB Type-B, AES\/EBU, coaxial, optical (TOSLINK), I²S, RJ45 Ethernet, and Bluetooth, with fixed-level balanced XLR (4.0Vrms) and RCA (2.0Vrms) outputs.
