Leben RS-28CX Premium Preamplifier
The Leben RS-28CX is a flagship vacuum tube preamplifier designed for the most discerning audiophiles. Unlike common NFB (Negative Feedback) designs, the RS-28CX utilizes a superior CR-type RIAA equalization system. This sophisticated approach, based on GE 12AT7 tubes authorized by the J.A.N. (Joint Army & Navy) standard, reproduces an incredibly clear and stable soundstage without the hardening effects of feedback. To achieve absolute sonic purity, Leben engineered a separate power supply unit housed in a dedicated chassis, effectively isolating the sensitive audio circuits from transformer noise and interference.
The line stage of the RS-28CX is equally impressive, featuring General Electric 6CG7 dual-triode tubes in a powerful SRPP amplification configuration. This system can supply a massive 80V of clean output signal, allowing it to drive any power amplifier, including those with very low input sensitivity. For high-sensitivity systems, a 5-step attenuator is included to eliminate residual noise. Crafted with premium components and finished with natural Canadian White-Ash side panels, the RS-28CX is a multi-award-winning masterpiece that represents the pinnacle of Leben's high-fidelity engineering.
