The new C-900u was created for the pursuit of uppermost tone quality. The balanced amplification circuit has a 4-module configuration with independent right/left and hot/cold sound signals to suppress unnecessary noise generation. A combination of the evolved traditional ODNF circuit version 4.0 and sturdy power supply unit has achieved a high signal to noise performance sound quality without distortion. The latest version of ‘Lecua 1000’, Luxman’s original fixed resistance switching type attenuator is used for the volume adjustment mechanism that is the major key of the control amplifier. The number of contacts is set to 88 to allow for more precise volume adjustment. the C-900u is elegant, user friendly with premium performance. An ideal match for the Luxman M-900.
