SUQIYA-F30A-Hi-end Dedicated American Standard Filter Socket + 500W Isolated Power Processor Subverts the Traditional Filter

Playing Hi-Fi, first play "electricity", this is basically a consensus; in the modern living environment, the quality of the power grid is getting worse and worse, and there is a lot of interference. Enough to make a good system drop several tiers in price.

There are generally three types of power supply improvement processing methods: EMI filter series, isolation transformer series, and regenerative power supply series.

Traditional EMI filters, due to their small size, are widely used in products with switching power supplies. They are used in switching power supplies. Their main function is to prevent the interference generated by switching power supplies from flowing back to the city grid. Conscientious switching power supply manufacturers Will be equipped with EMI filter.

Whether the traditional EMI filter can purify the noise of the city power grid, it can, but it has little effect; we believe that the more important role of traditional EMI is not filtering, but to prevent the interference of the switching power supply from flowing back to the city grid. Many HI-FI players also seem to have verified this phenomenon.

F30A is a Hi-Fi special power supply box launched by our team for enthusiasts. The filter structure is original, and the core devices use custom-level components under new material technology. The device is configured according to Hi-Fi requirements. of UHF noise and DC components.

UHF noise and DC components in the power grid exist simultaneously. UHF noise is commonly seen on HiFi-AV: the background is not clean and not dark, a little noisy, the resolution is not high, the low frequency is a little turbid, and the picture quality is clear And the contrast is not enough, the sharpness is not enough, etc.; the DC component is too high, and the transformer is called or vibrated. It is often heard late at night (the premise needs to be ruled out if the voltage is too high).

The original structure of F30A is equipped with targeted filtering of ultra-high frequency noise in the city grid and DC components in the city grid. It can be applied to almost all household HiFi-AV equipment (including power amplifiers) without negative effects.

The importance of the power supply in the audio system has been more and more recognized by the majority of audiophiles. A good power supply can be described as the basis and premise of a set of sound equipment. Without a pure and stable power supply, no matter how good the audio system is It will become rootless water and rootless wood. In recent years, with the rapid development of the national economy, the number of household electrical appliances has also increased rapidly, but the accompanying "power pollution" is also increasing day by day. At present, the interference factors to audio equipment in the mains can be divided into two categories. : One is the waveform distortion caused by various household electrical equipment; the other is the high-frequency interference caused by the ubiquitous wireless clutter (such as electromagnetic waves) in the space. So, what kind of power processing equipment can we choose to make a benign change in our sound system? At present, the power processing equipment on the market mostly adopts the design idea of stabilizing the voltage and filtering out clutter, but this design method can be described as "you can't have both." If used improperly, it will turn the performance of the audio system into another bad direction.

The so-called "electro-acoustic technology" means the close connection between "electricity" and "sound". The power supply is an important source of the entire sound system. There are extremely high requirements for electrical products, such as replacement of higher quality power cords, wall plugs and fuses. . . These methods can indeed improve the sound quality and performance to a certain extent, but they are only a temporary solution. Because if the mains is not "clean", no matter how good the power line is, it will not effectively block and interfere with these "impurities". For audiophiles with advanced audio systems, they often do whatever they can to invest in the power system. At present, some power supplies on the market are mixed, and there are many cheap ones, but many of them may bring serious side effects. The price of imported products is tens of thousands or even hundreds of thousands, and the price is far higher. to the affordability of many people. . . In addition to the price of our power processor that everyone can afford, its effect is comparable to tens of thousands of foreign power supplies. In the four years since its launch, its sales have always ranked first in the power processor category, and its excellent performance capabilities It has been affirmed by the majority of enthusiasts. . .

Actual performance:

First of all, it should be clear that the role of audio accessories in the whole set of equipment can only be fine-tuning. If the "three major pieces" of a set of equipment have been determined, then the tone of the main body has been determined. Don't expect accessories to bring earth-shaking changes to the system. Therefore, friends who have experience in playing with audio accessories may have a similar feeling, that is, these subtle changes brought about by the application of many accessories. There is an EMF switch on the machine panel, which can control its electromotive force stabilizer. If it is turned on, it will work. If turned off, it will pass through without interfering with the power supply. Therefore, in order to fairly judge how much skill there is, we used a blind listening method for AB comparison.

After many comparative auditions, we can feel that when it is turned on, it does have a benign improvement on the sound effect. The more obvious example is the string performance in Shaham's "Paganini For Two". When it is not turned on, the sound of the piano is slightly tight, with a little graininess, and the layering of the music needs to be improved. The music is purer, the background is clean, the sound field is natural, the sound of the violin is more moist, smooth and sweet, and the transparent music performance is as if we are breathing fresh air in the wild, which is very comfortable.

In addition, in terms of the performance of large dynamic music, it can still give strong support to the system. In addition to the various benefits mentioned above, it does not compress the dynamics of the music, but allows the notes to gallop in the free space, while adding more The contrast and stability of the music picture are a little less impetuous, allowing people to go deeper into it.

Many commercially available filters, including those for HiFi, are rarely equipped with DC component filtering.

The maximum current peak value of F30A is 30A. Under the high current peak value design, it has lower internal resistance of the power supply, stronger dynamic response speed, and greater power reserve. It is said that the power filter affects the dynamics in the market. does not appear.

Generally, traditional filters affect music dynamics. The main reasons are summarized as follows:

1. The customer's selection is not correct, that is, the power selection is small.

2. Vendor parameter false standard

3. Due to the cost limit of traditional filters, the internal resistance of the resistor is too large

4. Non-H-iFi special design, only for switching power supply products (the market demand for this product is very large)

Using the F30A, the effect does not need to be opened up. Our statistics: the power supply noise drops by 50MV, and the veteran fans can already distinguish the effect. The drop of 80MV is very obvious; the drop of 100MV, the general fan can distinguish it by one ear, and the first fever may be It takes 20 minutes.

F30A, our test result, the noise drops more than 150MV
