About the SL103
The Vitus Audio SL-103 is a high-end, fully balanced analogue line-stage preamplifier in Vitus Audio’s Signature Series. It provides five configurable line-level analogue inputs (three balanced XLR stereo pairs and two single-ended RCA stereo pairs), balanced and single-ended variable outputs, plus a fixed-level tape output. Volume is controlled by a relay-switched fixed-resistor network with 0.5 dB increments. It has no built-in DAC, phono stage, streaming functionality, wireless connectivity, or digital inputs. The manufacturer’s current SL-103 product page lists the Mk II specification with updated physical depth and specified 80-ohm variable-output impedance; older Mk I literature lists slightly different depth, operating consumption, volume-range floor, and 75-ohm output impedance.
