Japan Esoteric Grandioso C1 pre-amplifier power amplifier power split two-piece set new national bank genuine warranty
ESOTERIC recently announced the launch of the new Grandioso(Italian, equivalent to English magnificent, meaning magnificent and outstanding)Flagship series, this series includes P1 SACD/CD turntable, D1 digital-to-analog converter and M1 mono rear stage. Among them, the C1 flagship split power preamplifier. This set of preamplifiers continues ESOTERIC''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s master-level audio concept and is designed to pursue pure sound quality. It has the best audio technology in one to achieve uncompromising sound quality performance. In terms of appearance, it is not difficult to find that ESOTERIC has changed the original angular design to be composed of some sleek arcs, which will definitely give people a refreshing feeling.
ESOTERIC Grandioso C1 adopts a split power design. From the beginning of the power supply, it has adopted a dual mono design, that is, there are two channels on the left and right in a unit. From the power supply system to the input, output, and amplifier circuits, they are completely independent. In order to completely isolate the weak signal interference between the left and right channels, all the components of the left and right channels will be installed after fine matching to achieve better consistency.
Grandioso C1 is equipped with 4 sets of power systems to supply power for the input/output left and right channels respectively. The amplifying circuit part is a fully balanced high-voltage amplifier design, which makes the output signal more linear and provides high-voltage driving capability. Different kinds of post-stages are used together. Grandioso C1 amplifying components are designed with wideband audio mode to meet the requirements of the corresponding SACD''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s ultra-wide audio response. In order to achieve a high level of signal purity quality, the volume control uses a microprocessor to synchronously control the gain, the internal audio wiring is all 8N pure copper wire, the power line is 6N wire, high-quality matched WIMA capacitors and custom resistors It forms the main audio line.
The Grandioso C1 preamp mainframe uses a special upper and lower mezzanine reinforced alloy frame + design three-dimensional independent separate installation, the input/output left and right channel preamplifier and selection circuit board are separated on the left and right of the rear of the chassis, the upper and bottom layers, and the middle Separately by the frame of the chassis, the front part of the front chassis of the frame is the circuit control part of the left and right channels. Lines that may interfere with the audio circuit, such as power lines and control lines, pass through the T-frame of the chassis from the back of the machine."I"Separate the wiring in the mezzanine in the frame to reduce the slight influence of the power supply line on the amplifying circuit. It can cleverly physically separate the left and right channels and the input and output components to reduce mutual interference, and the heat dissipation is more reasonable.
The 4 sets of power transformers of the split power supply case of Grandioso C1 are placed in the middle of the case. This three-dimensional upper and lower mezzanine center frame design arranges the heavier components in the middle of the case, which can make the center of gravity of the machine more balanced. Achieve better vibration suppression ability, while the base of the transformer is connected with the heavy chassis bottom plate, which can provide higher rigidity and stability.
The chassis technology continues the advanced style of Esoteric. The thick aluminum front panel is cut from a single piece of aluminum, and it has been cut and polished for several hours to form an elegant streamlined appearance. It is matched with the newly developed high-rigidity integrated shock-absorbing cabinet. To ensure the stability of the machine, the thick aluminum material is used, and the power base plate is also specially used to thicken the aluminum plate as the foundation. At the same time, the metal machine feet with four fulcrums are used to eliminate the impact of vibration. The special component assembly method makes the overall chassis more rigid.
