RS-28CX is equipped with the CR type equalizer based on GE(General Electric/USA) 12AT7 authorized by J.A.N.(Joint Army & Navy) standard of US Army, and can reproduce a very high quality and clear sound without adding any NFB.

To avoid compromising on sound quality ,one of the solutions we adapted to totally protect the sensitive CR type equalizer from negative effects was to develop a separate power supply unit.
Likewise, some of the finest available high-end audio components were selected for the RS28C to keep the deflection of the RIAA curve below +/-0.3%.

Of course, the phono equalizer is only one of the strengths of the RS28C. Another notable feature is a very strong output voltage created by the Dual-Triode Tube 6CG7 of General Electric(USA) used for the line stage. Leben further selected the best quality tubes out of these and constructed a powerful SRPP type amplification which can supply power amplifiers with a maximum 80V of clean output signal.
In considering the fact that output voltage of a standard preamplifier is more or less 40V, the RS28C can output about two times as much voltage, which will drive power amplifiers with very low input sensitivity.
