Premium Direct Engraving Amplifier Pre-order Golden Voice E-550 Direct Engraving Circuit, professionally crafted audiophile amp

1〠Appearance part: improvement content: pure aluminum chassis is used, more precise processing technology is adopted, panel power button is square, which is more harmonious and beautiful overall. The color of the gold panel with a thickness of 12mm has been optimized for many times, and the unique gold is more noble and elegant. It not only has the luxury of Tuhao gold, but also has a warm color system with elegant music, more metallic luster and perfect workmanship

According to the design concept and font characteristics of the original machine, the typesetting is re made. No matter the head or logo of the panel, as well as various functional buttons and knobs, all use accurate silk screen to mark their functions. The font color is elegant, the size is coordinated, and the overall appearance is more striking and high-end

Acrylic panel is made of imported materials with higher transparency; The input selection is screen printed on the acrylic panel through multiple processes, which is clearer when used with blue LED indicator; The luminous LOGO has been tested and optimized for many times. The color is ice blue and has been subject to multi-level softening treatment. It is eye-catching, high-end but not dazzling, and can completely match the workmanship of the original machine; The delicate and transparent black acrylic frame sets off the luxurious, beautiful and dynamic feeling of the power meter; Add gold acrylic mounting nails, embellish the black beauty

In the back panel, the input RCA base is improved, and the imported pure copper CMC gold-plated socket is used to ensure the optimal signal input and extremely low noise; The horn base adopts pure copper crystal terminal, which ensures a more powerful power output capacity; The functions of each part are marked with silk screen, which makes the layout of each part clearer and easier to use

The chassis base adopts four gold-plated thickened machine feet with rubber pads, which have a more beautiful appearance and better shock resistance and more stable operation

The internal material Ding adopts the consistent principle of Seiko feverish production. Imported high-quality feverish components are used for welding and production. All components are welded with high-quality silver solder; Concentrated production in small batches to ensure stable quality and consistent sound; The output relay is replaced by the Japanese original Omron high current relay, which has higher reliability and longer service life; The internal wires are connected with high-purity oxygen free copper with large wire diameter to ensure the continuity of signal and current without damage; All the power amplifier tubes are precisely paired. First, the instrument is used to test the pairing. After the computer is powered on, the tubes are tested for many times. After aging for a period of time, the tubes are paired again to ensure more stable operation of the amplifier and perfect sound performance; The separately customized thickened transformer cover makes the sound more pure, the output signal to noise ratio higher, and the static distortion almost inaudible
