SP – 103
SP – 103 Signature Series

The Signature Series is the “core” of Vitus Audio’s lineup—devices designed to delight even the most demanding listeners.
The SP-103 is more than just another step forward—it’s a complete revolution. Drawing on the knowledge gained while developing the MP-P201, the Vitus Audio team designed the successor to the SP-102 entirely from scratch. The result is a sophisticated, modern piece of equipment that goes beyond the norm.
The SP-103 design incorporates many of the features found in the MP-P201. The same options for adjusting impedance or sensitivity are available via the RC-010 system remote control or the front panel. Instead of a typical MM/MC section, this model features flexible gain adjustment, selected based on the cartridge’s output voltage. The result is a perfect match between the settings and voltages ranging from 125 μV to 16 mV.
