The SP-103 is a phono stage from Vitus Audio, built with substantial gain and a wide MC loading range. The SP-103 brings Vitus's uncompromising Danish engineering to dedicated phono preamplification.

Key specs that matter

One balanced and one single-ended input are provided. MC current-sensing input impedance offers a wide range up to 2,000 ohms. Output impedance is 80 ohms. Gain is a substantial 75dB for MC or 47dB for MM. Frequency response extends up to an exceptionally wide 800,000Hz within plus-or-minus 3dB, consistent with Vitus's characteristically extreme bandwidth specifications. Total harmonic distortion plus noise is under 0.01%. At 100 x 250 x 250mm and 6kg, the SP-103 maintains a manageable phono-stage chassis reflecting Vitus's uncompromising engineering standards.

Sound and use context

Expect exceptionally clean phono-stage performance reflecting the low 0.01% distortion figure combined with the substantial 75dB MC gain, consistent with Vitus's broader uncompromising Danish engineering philosophy.

Pairing

Vitus's own amplifier catalogue offers natural, brand-coherent pairings for a coherently voiced, entirely Vitus-based system.

Alternatives

Other manufacturers' dedicated phono stages offer alternatives for buyers wanting to compare features at a similar price point.
