QUAD CLASSIC Valve Series
Quad QC Phono Stages
Quad offer two options for adding a phono input to their valve preamplifier.
A solid state module is available for the QC-twenty-four preamplifier, known as the QC Phono stage, this allows direct connection of a turntable with a internal switchable option of MM/MC, this can be fitted as standard or at a later date.
For audiophiles requiring a higher performance phono stage, Quad also make the Quad twenty-four P. The Quad twenty-four P is in the same size case work as the QC-twenty-four preamplifier. This dedicated valve phono stage has been designed by Tim DeParavicini for Quad. It has been voiced following intensive listening tests by some of the most respected “ears” in the music world. The twenty-four P has switchable MM/MC inputs and a choice of full level or variable level outputs. In a vinyl only system the twenty-four P may be used directly with a power amplifier using its variable output.
