The SMSL R100 is a compact R2R DAC built on two ADI AD1861J chips, with balanced XLR outputs and a parametric EQ you set up from a web browser. The SMSL R100 is a compact R2R DAC built on two ADI AD1861J chips, with balanced XLR outputs and a parametric EQ you set up from a web browser.The R100 takes a different route from most modern converters. Instead of a delta sigma chip it uses two classic Analog Devices AD1861 ladder DACs in the selected J grade, with a de glitch circuit and a precision MSB adjustment that SMSL calibrates on every unit. The result is the natural, unforced presentation that R2R designs are known for.Digital filtering is SMSL's own: an FIR filter with eight times oversampling and very deep stopband attenuation, a dedicated S/PDIF receiver algorithm to reduce jitter and a proprietary DSD conversion routine. The analogue filter is derived from the flagship VMV D3.A parametric equaliser is built in and is adjusted through the SMSL DSP Tuner web page, with no driver or app needed. Three modes are stored: Direct, EQ1 and EQ2, selected from the front panel. The CNC machined chassis has two clear windows so the circuit stays visible.Main featuresTwo ADI AD1861J R2R DAC chips with de glitch circuitryMSB precision adjustment calibrated on each unitBrowser based parametric EQ with Direct, EQ1 and EQ2 memoriesSMSL USB receiver, PCM to 768kHz 32 bit, DSD supportFIR digital filter with eight times oversamplingAnalogue filter design derived from the VMV D3Balanced XLR and single ended RCA outputsCNC machined chassis with two transparent windowsJAS Hi Res Audio certificationTechnical specificationsDAC chips2 x ADI AD1861J, R2RInputsUSB, optical, coaxialOutputsXLR balanced, RCA single endedOutput level3.5Vrms balanced, 1.75Vrms single endedTHD+N0.003% (90dB)Dynamic range107dB to 108dBSignal to noise ratio107dB to 108dBOutput impedance33 ohmsPCM44.1kHz to 768kHzDSDDSD64 to DSD512 over USB, DSD64 (DoP) over optical and coaxialPower consumption2.6W, standby below 1WDimensions170 x 39.8 x 136mm (W x H x D)Weight712gFinishSilverBuying from Dreamcrest AudioDreamcrest Audio Fidelity Ltd is an authorised SMSL dealer with around twenty years in the high end audio business.
