Engineering the Acoustic Truth
Authentic R2R Architecture
At the heart of the S.M.S.L R100 lies a dual-mono configuration of legendary ADI AD1861-J R2R DAC chips. Combined with an exclusive patented de-glitch circuit, it eliminates digital harshness and clock switching noise at the source. The result is a smooth, liquid, and lifelike sound signature that captures the authentic texture and warmth of classic analog audio.
Advanced Jitter Rejection
Overcoming the traditional limitations of R2R designs, the R100 features a proprietary high-precision clock algorithm that effectively suppresses jitter across USB, Optical, and Coaxial inputs. It supports high-resolution PCM up to 32-bit/768kHz and DSD64 playback, seamlessly blending the velvety body of vintage R2R with the transparency of modern formats.
