LUXMAN's pursuit of the uppermost standards of tonal quality has lead to the creation of the C-900u. Four independent modules in the balanced amplification circuit enable the hot and cold components of the left and right audio signals to be handled independently to suppress unnecessary noise generation. Combining an evolved version 4.0 of our traditional ODNF circuit and a robust power supply has achieved high signal-to-noise performance and improved sound quality without distortion. LUXMAN's original LECUA 1000, a stepped fixed resistance attenuator, is used for the volume adjustment system, a major feature of this new control amplifier. The 88 step range allows for more precise volume adjustment. This product is an appropriate centerpiece for any modern hifi system due to its elegant design, user friendly features, refined tone controls, premium tactile operation, and more. The high performance power supply circuit features a CI type power transformer, with equivalent capacity to that of our B-1000f monaural power amplifier. Applying the philosophy of "Power Amplifier Driver", the voltage amplification stage drives the connected power amplifier stage precisely with sufficient power and is regulated by four large capacity 3,300μF blocking capacitors. The delicacy and vitality of various audio signals are transmitted to the power amplifier with the support of this remarkably stable power supply with almost no small voltage fluctuations.
