2. Design concept:The sound effect is at least 100% of the “British A5”of the original machine.

A customer asked 1: Many of your machines are imitating famous works imported from 10,000 to 1 million. How effective is your imitating them? Why is the price so cheap?

Answer: Our machines require at least the same effect as the original machine, with 100% effect, and there are many models that can PK off the original machine. For example, a machine that sells 3,000 yuan can at least compete with a 3,000-dollar machine. During the brand promotion period, the price is super cheap, and the price will be gradually increased in the future. It will be the best and most expensive machine in the world.

A customer asked 2: There are also many domestic brands producing fever amplifiers in China, and some imported brands also have joint ventures in China. How does your machine compare to them?

Answer: Our design positioning is the top audio, the highest peak of human technology and tuning today, even entry-level machines are invincible. It takes several days for a team to complete one unit, and each component has been carefully studied and tuned. Compared with ours produced by other domestic manufacturers, I can''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t see where they are when I look back. The customer''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s evaluation of our products is: reverberation around the beam, three days without end, comparable to Shenqi.

A customer asked 3: There are a lot of tube amplifiers, and it’s not bad to hear the introduction. How does your machine compare with their tube tube machines? How should I choose?

Answer: The best and most expensive in the world are transistor machines. Good tube machines only belong to the mid-range price range of thousands to tens of thousands, and the sound effects are still far from the top equipment. Compared with our high-end electronic tube machine, except for the midrange, the female voice is more sweet and greasy than mine, no matter the treble, bass, sound field, resolution, dynamics, and appeal, our machines surpass all of them. It''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s not at the same level as us at all.

3. Reference line:The British “British A5” line of famous aircraft, the original aircraft sold for 20,000 yuan. Swiss “Gowen 29M” line of famous aircraft, the original aircraft sold for 30,000 yuan.

It can be seen from the figure that these two circuits are basically the same. The difference is that the British A5 uses ordinary materials, and the Swiss Gawain 29M uses fever materials + higher output power.

Our machines are based on their circuit design structure and sound style, and are made of fever materials that are almost the same level as the Swiss Gawain 29M. The production area of ??some components is exactly the same as the Gawain machine. For example, Gawain used the American Fairchild M42/M92 pair tube, and we also found the American one and so on.

Finally, the parallel tubes were replaced with 2 pairs of “Motorola”ON imported original NJW0281G/NJW0302G fever pair tubes (150W/15A/250V). This tube is more suitable for Chinese people''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s listening hobbies. It is very durable and never breaks.

Below is a channel diagram of the Swiss “Gavin 29M”. It is very similar to the British circuit structure, except that the UK uses ordinary components, and Gawain uses fever components + higher power, so the sound is more noble and delicate. The original machine will sell for 30,000 yuan.

The picture below is the internal picture of the “British A5” The materials used are very common, they are all Taiwanese JMC capacitors, and the craftsmanship is not very good. Two pairs of high-power tubes are output in parallel.

（A5 also has a pure rear stage, 4 pairs of high-power tubes in parallel, the effect is much better than his combined 2 pairs of tubes, but the price is more than 30,000）

"Motorola"ON imported original NJW0281G fever pair tube (150W/15A/250V):It has excellent linearity within 10A current, and the “radio and television”evaluation of this tube ranked first. Motorola''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s tube bass is very full, the high frequency is slightly darker than Sanken, and the sound is thicker. Suitable for classical, symphony, etc.

The well-known audio magazine "Radio and TV" 2008 third issue has a high test evaluation on the NJW0281G/NJW0302G newly developed and launched by ON Anmeisen (Motorola factory).
The sound performance of this pair of tubes is very similar to that of NJW3281/NJW1302. The sound is very dense and granular, and the density is also very high. charming. The pair of tubes has excellent control power, and the performance of the final stage working current is quite consistent when changing in a large range, and there will be no obvious change in tone due to the size of the working current.

American SPRAGUE capacitors, made in the United States:Some customers like the brand new Japanese “Ina ELNA”FOR AUDIO audio supplement capacitors, the price is the same)

It is a well-known brand that is recognized worldwide, and most DIY enthusiasts do not know it. The blue shell packaging is printed with black ink and has a unique appearance style. No matter how the variety is changed, its packaging color characteristics will remain unchanged for a long time. It is easy to distinguish it from the numerous capacitors.

If you simply talk about how good SPRAGUE is, you might disagree. If you tell you that these world-famous brands, such as KRELL, Mark Levinson, Cello, etc., which cost tens of thousands of dollars, they all use SPRAGUE as the main filter capacitor, maybe you will be surprised. Respectfully. It can be seen that its quality and reputation are by no means unfounded.

Compared with the Japanese ELNA electrolysis, the low frequency diving of the capacitor of the same capacity is not as deep as Sibi Shen, and the sense of volume is not as much as Si Bilai. The texture is quite good, full of elasticity, loose but not fat, turbulent but not muddy. The shape and texture of the mid-frequency band are full and solid but not hard, and the high-frequency band is smooth and delicate, good air feeling, and tight analysis power are also the characteristics of SPRAGUE. Known as the “excellent”, well-deserved!

（Remarks: US Sibi is now purchased by Japan Chemical, so the early Sibi brand capacitors have long been discontinued. Although the brand is now chemical, it is still produced with the original old Sibi technology and assembly line, and still maintains the original old Sibi The style of the blue coat has not changed for decades, generally called Sibi Chemical）
