A spacious sound stage opens up in front of you, filling the space beautifully. A miraculous experience unfolds where music breathes energy into life. What we sought for our flagship model was the ultimate expression in art form that is musical reproduction. \u003cbr\u003e\u003cbr\u003eThe C-10X is equipped with our new “LIFES” amplifier feedback engine and the latest version of our original electronically controlled attenuator, “LECUA-EX”, technologies developed to lead LUXMAN into our next century. Fully-balanced audio pathways are directly connected throughout the three-dimensional structure, achieving infinite silence, overwhelming instantaneous power, and a true sense of realism. This is the birth of the C-10X control amplifier, heralding a new era of pure musical reproduction. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eDirect, three-dimensional connections between fully balanced amplifier circuit and attenuator\u003c\/b\u003e \u003cbr\u003eODNF*, a unique feedback system that has been matured as epoch-making amplifier innovation that provides the natural sound quality of a non-feedback equipped amplifier by feeding back only the distorted components of the amplified signal. In 2021, when developing our M-10X flagship power amplifier, we delivered LIFES as a new amplification feedback engine in order to acquire more realistic, fresh and rich musicality and overwhelming audio performance and now it is at the heart of our flagship C-10X control amplifier, the first model upgrade in 10 years. For the volume control system, we refined our LECUA electronically controlled attenuator that switches over a series of fixed resistors arranged in order in the circuit. LECUA-EX, which reads the motion pulses of a rotary encoder entirely disconnected from the audio signal path, thoroughly suppresses sound quality deterioration and enables smooth volume control. Our LIFES preamplifier circuit is assembled with bespoke components and is directly connected to the LECUA-EX system, the four units being laid out in a fully balanced configuration in completely identical operational states to realize the ideal structure as a preamplifier. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eVarious control functions for controlling the audio system\u003c\/b\u003e \u003cbr\u003eAs a flagship model that stands at the top of our lineup, the C-10X not only has high-performance preamplifier circuitry that confidently drives the power amplifiers connected in the following stage, but also has a rich array of functions as a control center that adjusts the environment of the entire audio system. Preamplifier gain has been increased to 15dB (previous model C-900u had 12dB), allowing accurate handling of a wide range of levels from various input sources without distortion. In addition to a variety of output mode switching functions that allow you to select unbalanced, balanced or bi-amplified configuration, depending on your system, you can also use the volume shift function in 0.5dB steps via the electronically controlled attenuator LECUA-EX main volume control system. This allows you to adjust left and right balance (L: -6dB to R: -6dB) without causing deterioration, adjust the level for each output system in bi-amp mode (±6dB for each system) and adjust the output level for different listening situations. If it also equipped with an input offset function (0 to -6dB for each input terminal) that allows you to align the levels of multiple input devices, achieving a wide variety of control functions despite its simple circuit configuration. \u003cbr\u003e\u003cbr\u003e\u003cb\u003ePanel configuration with beautiful contrast\u003c\/b\u003e \u003cbr\u003eThe C-10X expresses bold and delicate slanted edges between the chassis and the front panel. The three dimensional and sensual housing design, common to both the M-10X and D-10X, embodies the overwhelming presence and high musicality of a flagship model. The finely machined, hairline finished aluminum top panel creates a beautiful contrast to the blasted white front panel. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eFluorescent display with excellent visibility\u003c\/b\u003e \u003cbr\u003eThe fluorescent display features a dimmer function and shines against the blasted white finished front panel with excellent visibility. We have also taken into consideration ease of viewing from the listening position. Normally this would display input and output volume levels, but from the remote control, the volume level display input and output volume levels, but from the remote control, the volume level display can be zoomed to four times the size. Additionally, the status of various function switches can be checked with LED indicators inside the acrylic panel. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eAbundant functions and easy-to-operate remote control\u003c\/b\u003e \u003cbr\u003eThe C-10X features an electronically controlled bass\/treble tone control, a volume-linked loudness function that matches human hearing characteristics, an external pre-input terminal that can directly connect to the pre-output of an AV amplifier. A balanced connection phase preset function that can be set independently is provided. Also included is an aluminum remote control that providing comfortable operation of most of the C-10X’s functions at your fingertips. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eNewly developed weight rotation mechanism\u003c\/b\u003e \u003cbr\u003eThe LECUA-EX volume control combines a high-precision rotary encoder with a newly developed weighted rotation mechanism to achieve high reliability and a high-quality feel as you rotate the large, machined aluminum knob over 192 discrete steps from 0 to 95.5dB. A tactile setting that smoothly accelerates the volume increase\/decrease by increasing rotation speed or pressing and holding the remote control, provides a comfortable volume operation that surpasses conventional volume devices that use variable resistors. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eHighly regulated power supply\u003c\/b\u003e \u003cbr\u003eIn order to embody the idea of abundant energy that accurately drives the power amplifier stage within sufficient margins, the power supply section of the C-10X is equipped with a powerful CI core type power transformer and seven custom specified 3,300 μF filter capacitors achieve dedicated highly stable power supply smoothing for each channel.
