The Flagship Preamplifier Defined by Four 300B Direct Heated Triodes A preamplifier is far more than an input selector or volume control. Its true purpose is to preserve the integrity of the musical signal from the source while allowing the power amplifier to perform at its absolute best. The L-10000 Signature is Allnic Audio’s flagship preamplifier, evolved from the acclaimed L-10000 with a completely redesigned circuit topology and power supply to achieve an even higher level of performance. At the heart of the L-10000 Signature are four 300B Direct Heated Triodes, with two tubes dedicated to each channel. Traditionally used as output tubes in high-end single-ended power amplifiers, the legendary 300B is employed here in the gain stage to maximize its exceptional linearity, rich harmonic structure, and natural tonal character. This unique implementation allows the preamplifier to reproduce even the finest musical details with remarkable accuracy while preserving the emotion and realism of the original performance. The left and right channels are built in a completely independent Dual Mono Mirror configuration, minimizing crosstalk and ensuring superior channel separation. A newly developed power supply further reduces ripple noise and power fluctuations, providing an exceptionally stable operating environment. The result is a significantly lower noise floor, greater resolution, and an expansive, three-dimensional soundstage. The input stage utilizes the ECF802 vacuum tube, while Allnic’s renowned 61-Step Constant Impedance Attenuator (CIA) has been further refined for the Signature model. Unlike conventional potentiometers, the CIA maintains a constant impedance at every volume setting, minimizing frequency response variations and phase shift while preserving the finest musical information. Every aspect of the signal path has been carefully optimized. The circuitry features the shortest possible signal path, premium selected components, and meticulously engineered internal wiring to minimize signal loss. This uncompromising design delivers exceptional transparency, dynamic expression, and musical naturalness. The L-10000 Signature is not designed to impress through artificial coloration or exaggerated frequency balance. Instead, it reveals the full potential of the entire audio system, faithfully conveying the spatial information, tonal nuances, and emotional depth captured in the recording. With its four 300B Direct Heated Triodes, the latest 61-Step Constant Impedance Attenuator (CIA), and a completely redesigned Dual Mono Power Supply, the L-10000 Signature embodies Allnic Audio’s philosophy of reproducing music in its purest form. It stands as the ultimate expression of the company’s flagship preamplifier design. Remote controlled 61-step constant impedance attenuator Mr. Park has completed development of the world’s first 61-step, constant impedance, “bridged” type attenuator. Allnic’s new attenuator is now the most sophisticated on the market, and we believe, without a doubt, also the absolute best sounding. With fixed impedance and no (± 0db) channel unbalance at any volume level, the new attenuator will astound users with its elevation of the fidelity and purity of any system in which it is used. This revolutionary and currently unique, oil clutched, motorized attenuator will be standard equipment on the L-8000 preamplifier and L-10000 OTL/OCL, L-9000 OTL/OCL, L-8500 OTL/OCL preamplifier. OTL/OCL Ciruitry OTL/OCL means “Output Transformer-Less” and “Output Capacitor Less”. In an OTL/OCL preamplifier, there is no coupling device between the preamplifier and the power amplifier, that is, the preamplifier’s final output tubes are directly connected to the power amplifier. Normally, an Output Capacitor or Output Transformer for separating AC music signal from the DC operating potential; if this is not done, the latter will destroy the power amplifier or loudspeakers. But these two types of coupling devices are effectively obstacles to signal transmission that add their own character (color), increase distortion, and consume small signals according to physical efficiency theory. In addition, they limit signal dynamics. Because of all these adverse effects, OTL/OCL has been considered the best solution for amplifiers in order to maintain signal purity. Some circuit experts might worry about DC potential in the music signal, but there is no need to worry. Allnic uses a “floating power supply circuit” which prevents the creation of any DC potential in the first place. Soft-start Circuitry Allnic uses soft start circuitry that, after sufficient warm-up only, provides the high voltage supply to the plate of each tube. This protective design results in prolonged tube life and fewer and less frequent issues with tube performance. Beautiful 100kHz square wave response We can show you how beautifully a 100kHz square wave response is reproduced. New vacuum tube damping technology Allnic Audio’s patented “Absorb GEL tube damper” technology prevents harmful vibrations from reaching the signal/gain tubes and, therefore, prevents micro-phonic noise propagation in the tubes. The Allnic Audio Absorb Gel damper technology effectively solves a problem that plagues most tube amplification systems. Provided other tube components do not introduce micro-phonic noise into your system, with the Absorb Gel damping system, you will enjoy a degree of transparent sound that will surprise and please you. Powerful driving circuitry Allnic believes in the importance of using high-quality, low noise and powerful driving circuitry in all its amplifying devices. Therefore, for example, in the M-3000 mk2, we employ the E282F tube (E55L for M-5000) in triode mode as the second stage driver tube, with a load of about 6 k ohms, and using 20 mA of current. The listener can easily hear and even “feel” the differences between this design and other, more conventional, ones. Please imagine, as you listen to the M-3000 mk2, its sound compared to the sound of an amplifier with conventional 12AU7 or 12BH7’s used as drivers, with a load of about 47 k ohm, and using 2 to 3 mA of current. Analogue power tube current monitors In order to provide constant current (bias) monitoring for the power tubes, Allnic uses a separate analogue current meter for each tube. The meters make it exceptionally easy to see the status of each tube at any time and to respond immediately to any variation in bias by use of the bias control knob for the relevant tube. The meters offer a simple, unambiguous indication of each tube’s status compared to conventional LED bias monitors.
