Aura LCC1 - Preamp/Headphone Amplifier

Headphone/preamplifier designed with a discrete, fully balanced circuit configuration. The control amplifier LCC1 is designed to complement the LCP1 power amp. Yet its purpose goes far beyond simple pairing; the LCC1 is built on an uncompromising design philosophy that prioritizes the essential core performance of a control amplifier handling delicate signals. Equipped with a full-balanced high-performance headphone amplifier section, the LCC1 embodies Aura’s unwavering commitment to analog amplification. Once you experience its performance, that passion will be unmistakably clear. Made in Japan, where minimalism meets high performance. At first glance, its compact size might suggest the use of a switching power supply—but every model in the Linear Classics series is equipped with a custom-designed toroidal transformer that powers a genuine linear power supply. Multiple power circuits and a dual-amplifier balanced architecture are implemented with no compromises. Within the limited internal space of each unit, only the essentials are retained, eliminating waste through purposeful design and precise engineering.　Aura’s minimalist philosophy resonates deeply with Japan's craftsmanship culture. By introducing strict dimensional regulations, the design achieves not only functional excellence but also profound meaning and visual elegance. Manufactured entirely in Japan, the Linear Classics series is produced with meticulous attention to detail—most of its processes are completed by hand, reflecting the spirit of true artisanal mastery. Pure Analog Philosophy That Endures The Linear Classics series is built on a foundational concept: a pure analog design centered around linear power supplies and analog circuitry. While providing region-specific transformers poses higher cost challenges, it is a necessary investment to deliver the low-noise, high-density sound that only true linear power can achieve.　By eliminating digital inputs and outputs, the series substantially reduces noise interference. Externalizing devices equipped with fast-cycling digital chips is a deliberate decision—one that protects the integrity of the analog signal and ultimately ensures the long-term value of the product.　In an era driven by disposability and fleeting trends, Aura’s commitment to analog purity is a quiet assertion of timeless design and enduring performance. The LCC 1 Headphone / Preamp features ● Dual-MOSFET Fully Balanced Circuit Design of Headphone amp　 The LCC1 is engineered as a fully balanced headphone amplifier using discrete dual-MOSFET architecture. Each channel (Left/Right) is driven by two matched pairs of EXICON ECX10P20/ECX10N20 power devices—totaling eight MOSFETs. This configuration delivers high-end performance without relying on integrated circuits, ensuring pure analog signal amplification. Note: Only the initial balanced conversion stage uses an op-amp.　 ● Hand-Assembled Discrete Surface-Mount PCB The main circuit board is built with a fully discrete surface-mount layout. All components are carefully installed by certified technicians in Japan, ensuring exceptional craftsmanship and reliability. ● Innovative Internal Construction and Noise Countermeasures The main circuit board is suspended from the top lid, a method previously adopted in the VA 40 rebirth model. Recognized for contributing to an open and natural tonal character, this board-suspension approach has also been implemented in both the LCP1 and LCC1 units. On the rear of the LCC1 board, a copper foil sheet has been applied for magnetic shielding. The material for the top lid, which supports the board, was selected from options including ceramic, Corian, and solid aluminum, ultimately settling on pure carbon for its superior vibration damping properties and sonic performance. ● Power Supply with Custom-Made Toroidal Transformers The power section of the Linear Classics series utilizes specially designed toroidal transformers to fit the internal volume of the units. Although preparing power transformers for 100V, 110V, 125V, and 230V may seem outdated, we believe that low-noise linear power supplies are a vital choice for analog circuitry. Additionally, the power supply for the motor that drives the volume control in the LCC 1 is completely isolated, using a compact transformer to ensure it does not affect the signal circuit ● Use of High-Grade Components Premium parts such as VISHAY metal film resistors and high-end capacitors including UKA, UUQ, and UCQ have been incorporated throughout the unit to ensure uncompromising performance. ● Artistic Enclosure with Meticulous Detailing The Linear Classics series features a front panel made from extruded aluminum. At its center, a silver stainless steel panel with elegantly curved sides is precision-fitted into laser-carved recesses just millimeters deep, presenting a seamless flat surface. This silver panel, emblematic of Aura’s design identity, is applied to both the front and rear top sections of the LCC1. Each panel undergoes chrome plating and is hand-polished to achieve its striking luster. The side panels are crafted from solid steel, and the LCC1 chassis itself is constructed from a fusion of four distinct materials: aluminum, stainless steel, carbon fiber, and steel. ● Expansion-Oriented Features The LCC1 is equipped with trigger connection terminals that allow synchronized power on/off operation when linked with the LCP1 via a dedicated cable Aura LCC1 Specifications Type: Stereo Preamplifier / Headphone Amplifier Input Terminals: PHONO (MM) ×1, XLR ×1, RCA ×2 Output Terminals: XLR ×1, RCA ×1 Headphone Output: 4.4mm (Balanced) ×1, 6.3mm ×1 Input Sensitivity: XLR 400mV, RCA 400mV, PHONO (MM) 5.9mV Input Impedance: XLR 100KΩ,RCA 50KΩ,PHONO(MM) 47KΩ Rated Output: XLR 2V, RCA 2V Output Impedance: XLR 200Ω, RCA 100Ω Maximum Input Voltage: XLR 7.5V, RCA 4V, PHONO(MM) 100mV Maximum Output Voltage: XLR 14V, RCA 8V Frequency Response: 20Hz–20kHz +0dB, -0.2dB(RCA at rated output) Total Harmonic Distortion: Less than 0.003%(RCA, at 1KHz rated output) Signal to Noise Ratio: RCA 113dB, PHONO(MM) 83dB(IHF-A, at 1KHz rated output) Power Consumption: Approx. 20W, Stand-by : about 1W Dimensions: W430 × H71 × D332 mm Weight: 6.5Kg Remote control included
