Ready to write a piece of clothing forty-four articles: The site of the first song poetry X20pro decoder & Olaer Aune S7 balance amp brief review

Recently, two machines have become more popular. One is the pure decoding X20pro of Geshide and the other is Aune's fully balanced amp S7. I just recently listened to the two popular machines and talk briefly. Next to me, I will not say more. Start with X20pro.

I. Geshide X20pro

This machine actually I was not very interested in the beginning, because I was under the impression that the decoding of Lao Huang was not particularly good. I heard the old version of the X20, the quality is OK, but the voice is a bit harsh to tell the truth. A while ago I also reviewed his home machine A20H, the amp is very powerful, although the decoding part is a lot better, but still some tight, the sound can not be opened, listening tired. Before the value of friends asked me how to x20pro, I thought it was said that the old x20, found that the wrong, and a few friends have heard x20pro after the evaluation is very good, there is a friend is directly under the order, to remind With my interest, I went to a friend to borrow one.

This machine is actually only Huang himself selling, Taobao search which is the cheapest store in his home, this is the normal price, and the other several prices that look really a bit scary. . .

â–² Geshide's packaging is simple. It is a double-layer corrugated paper box. The machine's two ends are covered with a large foam cushion cushion. A lot of hifi equipment manufacturers are in this style, relatively simple, no fancy packaging, but strong enough to be safe.

â–² x20pro's appearance continues the old x20, the details of a slight change, the top is still the same cooling holes.

â–² A knob on the front and the left of the fuselage is the display. In fact, on the left is the power switch, which is the same knob as the right side for beauty. Click the right knob to switch the input source, long press to enter the menu.

In addition, I feel that the display in the middle can actually be larger, look better, and the screen is too big. Don't look at the settings every time. For example, the display in the middle of the Aune s6 looks comfortable.

â–² The left side of the back of the machine is the output area. Each XLR and RCA group supports the digital volume front stage. In the middle is the digital input area, USB, HDMI interface i2s, RCA coaxial, BNC coaxial, AES each one, the interface is complete. On the right is the power cord jack, which can be used to switch between 110V and 230V as needed.

â–² The X20pro's remote control and drive unit contained a single box. This box is quite sophisticated.

â–² The box contains a warranty card, a drive tray, and a remote control. The remote controller is the same as the A20H, but the standby button is useless. I do not know why the X20pro does not have a standby function. Another mute function looks like it can only be achieved through the remote control.

老 To be honest, at first I still listened with a skeptical attitude, but after the opening, the first reaction was to hold the grass. This machine quality I have expected, after all, with the 9028, Lao Huang's machine quality is no problem. In fact, the quality of X20pro is quite reasonable, higher than I expected, and it is significantly higher than the classic model Nuwave. It is impolite to say that if the competition is of pure quality, it can be counted as less than 10,000 yuan.

If it is only of high quality, there is actually nothing to be missed, because there are many domestic quality machines and a lot of good quality, but most of them do not sound well. The biggest problem is that the actual sound of this cargo is not at all tight, and the overall feeling is actually loose! To tell the truth, this is more surprising. At similar and even higher prices, the quality machines I have listened to are at best not too tight, and there is no such sense of relaxation. Before the low-priced machine, I think that the Shanling h1.2 has refreshed my three views before, and I did not expect to be refreshed again this time. This machine has a wide sound field, a bit low to mid-range, high density, and low-frequency sound. Listening to classical music is a good hand. It can be said that it is difficult for you to find a machine that is more symphonic than it is at the same price or even at twice the price. Listen to fashion, do not grasp the ear, a little bit of moisture, but not too bad, belong to the level of hearing can be decent, with the Elear, HE400i this vocal flavor better headphones can effectively make up for the lack of vocal.

â–² While connecting the amplifier to the nv4000, it still feels a slight difference. X20pro resolution is close to 4040, but the sound field is slightly smaller, mainly in depth. Laterally, the margin of the sound field is slightly wider than 4040. The gap in density and analysis is not too big. The most important difference is in the relaxed natural sense of the voice. In addition, the voice 4040 is also quite nice.

X20pro can have such a performance. To be honest, it is far beyond my expectation. It is currently the best price-to-performance ratio for listening to classics at the price of 10,000 yuan. He likes to listen to classical friends and must try it. If pure vocal currents do not care about the quality, perhaps the Ming 1704 is more suitable for you. 1704 I only heard v3, so I heard the uk version of v4 come back and talk about it.


II. Aune S7

Some time ago, Aune announced the balance of the machine S6 and fully balanced amp S7, S6 I had before the sun. The S7 refers to the circuit design of Titans' Artemis amp. Artemis is a very good transparent amp, I have played one before, I feel that the price is very high, is only sold in kit form, the amount is relatively small, so although the reputation is good, but not many people played. In addition, Artemis has a problem that only supports a set of balanced inputs, which is troublesome to use.

This time, Aune launched the S7 and strengthened its driving force. As an official product, the interfaces and functions are also more perfect. Personally feel that in a sense it can be regarded as the final version of Artemis. The S7 also continued Aune's consistent pricing, and the new 2980, which is cheaper than the channel price of iha6, so I borrowed one to listen.

â–² S7's outer packaging continues Aune's style, black on the black.

â–² The internal space is compact, filled with sponge, and provides effective cushioning. Basically, courier accompanied by cartons and boxes is not easy to throw violence.

â–² S7 and S6 are basically the same size and style, there is an arc above, the bottom of the front panel will be flat, but there is a curve with the same arc as the top curve decoration.

The front panel is from left to right single-four balanced port, double-three balanced port, single port, input indicator, gain indicator, gain / input switching button, the rightmost is the volume knob. This gain/input toggle button I want Tucao, short press to switch input, long press to switch gain, to be honest why not add a button to make two independent? The front panel has a lot of free space.

â–² On the left side of the back is a set of RCA and XLR analog inputs, and on the far right is the power jack and switch. Here still want to spit it, the power switch is still suitable in the front, after all, civilian equipment, if placed on a small shelf against the wall, to press this switch will be more laborious.

â–² With iha6, the two are similar in height, S7 is wider, and iha6 is slightly longer than s7. In terms of button layout, personally feel that iha6 is more beautiful, and use a composite port, which can double three/single 6.5 multiplexing, saving space is also very convenient.

3k price amps, especially balanced balanced release, and iha6's contrast is bound to hide. Iha6 is an amp that I really like, beautiful appearance, sound. I used to go in and out of the equipment and left iha6. It was because there was no strong competitor at a similar price, and the appearance of the S7 ended the situation.

â–² On the sound, the S7 did continue Artemis's overall style. The tri-band equalization was transparent and the driving force was strengthened compared to Artemis. Compared with iha6, the big style of the two machines is balanced and transparent in one direction. The quality of the balance is similar. The S7 driving force and the low frequencies are slightly better. The iha6 sound is slightly warmer and tastes better. On the single port, S7 is significantly enhanced compared to iha6. The iha6's single port has a large gap compared to the balance port. Although you can use it, if you have heard the balance port, you do not want to use the single port of the S7. However, although the single port of the S7 has a gap from the balance port, it is not so The big gap makes people feel that they can accept it.

In terms of headset adaptability, the iha6 pushes the flat-panel headphones a bit better, and the S7 feels a little better. Both are more suitable for high-impedance headphones in general, and there is no high resistance for low-resistance adaptation. However, the adaptation effect of S7 for low-resistance headphones is slightly better than that of iha6.

On the whole, the volume and quality of the two amps are similar, S7 is slightly better. Although the iha6 price is high, but the brand new 3k can get the goods, the appearance of second-hand two-seventh, so basically in the same price as the S7, can be described as opponents. Which of these two can be bought, but taking into account the S7 brand new only 2980, catch up with activities or to accept second-hand will undoubtedly be cheaper than iha6, can be described as excellent price, so if you plan to buy amp, personally recommend buying S7. For those friends who already have iha6, there is no need to toss, because more is the difference in style and subtle differences, there is no significant difference, it is not worth tossing.

Three. Summary

The two machines in this review were very good, especially the X20pro, which was the second surprise for me after listening to so many devices. The first one was Mountain Spirit H1.2. If you need to purchase a decoded amp in the near future, you can consider these two devices. Listen to classical words, if the budget is sufficient, then X20pro+S7 will be a very good combination, loud and big dynamic, high density, sound with a certain degree of looseness, highly recommended. And like to listen to vocal friends, you can consider H1.2 with thor, the overall more run better taste; if you are willing to wait, the decoding can also be considered Mingda 1704, loose natural.

IDC Socket Connector

Antenk Insulation Displacement termination connectors are designed to quickly and effectively terminate Flat Cable in a wide variety of applications. The IDC termination style has migrated and been implemented into a wide range of connector styles because of its reliability and ease of use. Click on the appropriate sub section below depending on connector or application of choice.

An insulation-displacement contact (IDC), also known as insulation-piercing contact (IPC), is an electrical connector designed to be connected to the conductor(s) of an insulated cable by a connection process. The IDC forces a selectively sharpened blade or blades through the insulation, bypassing the need to strip the cable.

IDC Plug / Socket - Card Edge Slot Connector

Card Edge SLOT Connector is the portion of a printed circuit board (PCB) consisting of traces leading to the edge of the board that are intended to plug into a matching socket.


IDC Connectors
The IDC connector is also known as an insulation-displacement contact, or insulation-piercing contact. It is a connector designed to work with ribbon cables, and uses sharp contacts to clamp onto the wire, piercing the insulation and connecting with the wire in a secure and convenient way.
This simple connection principle is ideal for multi-stranded ribbon cables, as it allows the connector to make an assured connection across the multiple wires without having to strip the wires. This cold welding connection may ensure a gas tight connection between the wire and connector.


The Antenk range of IDC connectors includes plug and sockets in configurations to suit your purposes.

IDC Connectors Applications
IDC connections are often used low voltage applications, such as to connect computer drives internally or to connect computer peripheries. They are often cited as preferable due to their having much faster installation speeds than conventional wiring connectors.
IDC connectors also have an advantage in that several IDC connectors can be attached to the same length of ribbon cable, able to handle multiple connections economically, saving time in more complicated installations.

IDC Connectors Features and Benefits
• Fast cold welding connection
• Cost effective
• Versatile
• Quick termination to wire.
