Sound description:
The voice is warm, rich in overtones, and never tired of listening. The voice is sweet and delicate, and the details are excellent. The bass is deep and flexible when diving, and the treble midrange is smooth and soft. It is durable and magnetic.
Product introduction:
1: The vacuum tube is 5670 imported from Singapore, and the sound is warm and transparent. It can also be upgraded to Russian EH6922, with a more detailed sound and a better sense of hierarchy, plus 30 dollars.
2: This machine maintains the characteristics of the courage machine, which is mellow and full of musical flavor. At the same time, it combines the advantages of discrete tubes in terms of characteristic dynamics, transients, high and low frequency response, analytical power, signal to noise ratio, and so on. In terms of sound field and permeability, it can keep pace with the imported first class of tens of thousands of yuan.
3: R-type transformer is adopted, with higher resolution and higher fidelity. German original Mundorf Mcap EVO oil oil immersed coupling frequency division heating capacitor.
4: It is designed with circuit board, and the internal layout is more reasonable, neat and beautiful.
The front panel adopts silver 8mm thick aluminum alloy electroplating wire drawing process panel, blue power indicator tube, and a unique electronic tube display upper cover plate grid, with a higher grade
5: The service life of advanced fully sealed switch controlled by traditional rotary switch is long.
6: Input signal provides two sets of inputs, gold-plated RCA and balanced NEUTRIK high-end XLR input
7: The output signal provides two sets of outputs, gold-plated RCA and balanced NEUTRIK high-end XLR output.
8: The three plug socket is used for the power incoming line, which is convenient for replacing and upgrading the power cord. A power grid filtering and purifying circuit is designed to filter out the clutter and DC components in the power grid.
9: Antique oil immersed capacitor and imported polypropylene capacitor coupling such as WIMA are used. High performance R-type transformer is used for power supply, with high price (ring transformer and square transformer have large magnetic leakage, large radiation noise and low efficiency, while R-type transformer has high efficiency of more than 90% and very small magnetic leakage).
10. The original imported electronic tubes are used, and the original imported discrete tubes are perfectly combined.
11. The pond filter capacitor and the adjustable voltage stabilizing filter constitute an accurate filter circuit with good filtering effect, and suppress the residual noise.
12. The filament of the electron tube is powered by AC, which is warmer and more durable than DC, and will not cause sound hardening, thus prolonging the life of the electron tube. The interference of the filament is reduced.
13: Mature design, outstanding sound quality and stable performance. This machine can be connected to a pure power amplifier, or can be connected to a parallel machine as a voice regulator to further improve the sound quality and enrich the detailed performance.
