National Brick Kai N5: A pragmatic work done by Shaoyou

To be honest, domestic professional audio players have risen suddenly in the past two years, and they have greatly recovered from the ice. Of course, in part, thanks to the mobile-portable HiFi concept spurred by some smartphone manufacturers, indirect improvements have been made to ordinary audio. The enthusiasts' cognition and pursuit of taste brought a lot of fresh blood to this niche minority professional HiFi circle. In the author's opinion, the professional player products that can really open the level transition between ordinary audio enthusiasts and HiFi enthusiasts still have to reach the level of 2,000 yuan. It is no wonder that many audio manufacturers have introduced the price of the country. Brick products.


Of course, it's not that the entry-state tile of the thousand yuan file performs poorly. It can only be said that the comparative advantage of the “ HiFi phone ” that the city will play is not obvious. This is for the first time burning users, the first face of the face value problem is a major weakness of the national brick, after all, there is no reference to the mobile phone godfather Apple blessing, relying on manufacturers own YY drummer out of the player's product design naturally will inevitably lead to Consumer groups have mixed opinions. In countries where the brick industry is undoubtedly the most innocent tucao is brand Kay tone Spark (Cayin) high-end player N6, with "singing washing machine," the award is also considered to be very famous.


This time, the author shared another professional player N5 with a price of RMB 2,000 in mid-range after Kai Yin and N6 . Although there are many innovations in design, manipulation, and sound quality, the price is also closer to that of N6. However, in the end it did not escape the slogan of “ will sing and sing the washboard ” . It seems that Kaiyin will start home appliances in the morning and evening. Of course, the joke is a joke. In fact, Kaiyin is considered as a pragmatic audio manufacturer, at least in the Shaoyou Circle. After Tucao banter was finished, the quality of performance was still recognized by everyone.


| Designs

As far as the outer packaging of Kaiyin N5 is concerned, this is the most rustic and low-key style I have seen in the price player product, and I didn't even take the kraft paper box. It is also a mid-priced product of 2,000 yuan, which is completely dark. The box is only printed in the upper left corner of the brand name is not obvious, for the first time users do have some doubts, but fortunately to open the lid to see the moment of deity, will restore a lot of forcing a sense of loss.


The back of the box is no longer monotonous, with the bright orange and black eye-catching, focusing on the features of the product features and the main technical parameters to be identified, of course, in order to allow everyone to better understand the Kayin N5 , the author will later on the product features and configuration Introduction to parameter expansion.



Providing two accessories standby screen saver film, silicone sleeve, coaxial output line and the USB 3.0 cable. As you can see, after wearing a silicone sleeve, the Kaiyin N5 is safer to protect, but it is instantly lost to quality sensitization. Therefore, the advantages and disadvantages are considered by the benevolent wise men.


In fact, the color tone of the N5 in terms of appearance and color value is still more than the previous N6 , at least in the shape of some small ideas, obviously is the memory of the classic cassette design, but was burned to stare at the position of the washboard is not blinking, It is believed that the designer of Kaiyin is ruined. Of course, in my opinion, the shape is matched with the dark gray aerospace aluminum alloy CNC case. Does the visual sense have a kind of post-modern retro style?


The three-dimensional dimension of the Kaiyin N5 is 64 mm (W) × 111 mm (L) × 16.4 mm (Thick), and the body weight is 195g . The portability performance of the Kaiyin N5 is better than before. In addition, with regard to its size, and the circular transition of the rear frame, one-handed holding is very easy and it does not feel handy at the same time.


From the perspective of the front design of the Kayin N5 , simple and intuitive is divided into the upper display area and the main control area below, and the design of the physical button + multi-function dial is also currently the mainstream, but the M menu button does not Follow the trend on the front. In addition, the three buttons for the return, song switching, and the dial wheel with the play / pause function in the middle are all made of metal materials and are adorned with coffee colors. The more frequently used turntables in daily operation are provided with solar lines, so they have a certain degree of non-slip friction, and they perform well in the sense of passage and damping control. The overall control is still accurate.


The intuitive look of the 80% area on the back of the N5 is still quite carbon fiber. However, the logo type on the back panel is printed on the covered acrylic. If you want the back to look clean and tidy, you can remove the film. Of course, follow-up use, then we must be careful to use anti-scratch friction.


From the left side of the fuselage, it can be seen that the M menu key normally appearing on the front is located immediately below the volume increase/decrease key, and at the same time, it is given a number of practical shortcuts such as deletion on the playback interface. Or favorite favorite songs, play / pause function can be realized in the lock screen interface, and it is indeed designed to be more convenient on the side.


The top of the fuselage from left to right are balanced headphone output, line output / headphone output, coaxial output, and power button. It is worth mentioning that when the headphone output is based on an official propaganda that can support the impedance of the 16-300 Euro section, this thrust completely ignores the tempo of the amp. In addition, the user-friendly aspect is to select the line output, N5 will pop up the default maximum volume warning message, the user must confirm the selection to take effect, you can avoid the wrong choice leading to damage to the headphones and human hearing damage.


As can be seen from the bottom of the body of the Kayin N5 , it uses a dual TF card slot design, and supports 256GB of storage expansion. Of course, in addition to having a large amount of storage support, the N5 provides USB3.0 data transmission rate guarantee is also very bright, up to 5.0Gbps transmission rate is absolutely high-speed channel for large-capacity lossless music.


| Hardware configuration

In terms of hardware configuration, the Kayin N5 uses the audio architecture solution of the JZ4760B+SA2000+AK4490EQ , which directly supports native hard-to-get DSD and direct solution to SACD-ISO images. Of course, the lossless formats such as mainstream WAV and APE must also be supported.

Among them, Jun Zheng’s master has learned that it is very popular, but the practical stability still stands the test of being the best choice for most of the country’s bricks.


The biggest highlight of the hardware aspect is that the chip is derived from AKM 's AK4490EQ decoder chip, which can operate in both PCM and DSD modes to achieve true native hardware DSD . And through the use of OPA1662 to achieve low-pass filtering, AD712 as a voltage amplifier, and four BUF 634U as amp drive output, and ultimately for the audio signal reduction capabilities and details of the resolution have a long way to go.


For life Kay sound N5 is, in actual use the author found that hibernation function in the standby built N5 4200mAh lithium complex system, can be maintained substantially normal to use more than 8 hours of battery life. Incidentally, the charging and data transmission are backwards compatible, and the USB 2.0 Micro USB cable is also supported for use. In addition, there is a hidden orange LED flashing next to the dial.


| System Experience

First of all, in terms of product fluency, the Kaiyin N5 has performed well from startup to system control, and the system UI interface is very close to what the author is familiar with, and may be based on the same positive solution, and the same Cooperation with Seashell has its origins.


In today's era of high-resolution mobile phone screen, the screen parameters have always been pain points that the national brick can't show off. Similarly, the 400 -inch 2.4 -inch IPS screen used by the Kai N5 is not too bad in the country, but it can only be said Still stay in Nokia's sentiment era, expect Retina retina screen is obviously unrealistic and not much practical significance. Fortunately, the actual visual perception is not exquisite, but the font content is still quite clear. In addition, it is somewhat interesting that the author finds that the built-in 4 sets of themes are very distinctive in the homepage interface, and the violin, piano and other shapes are integrated into them, and the menu selection is also combined with animation.


The music setting menu is mainly for the high and low gain settings, and the digital filter partition is more detailed, ranging from steep drop to super slow drop in 5 steps . In addition, the DSD gain compensation is up to +6dB , and when SPDIF Out is output for local playback of DSD64 music, It is also possible to switch formats between D2P and DoP to meet the needs of different user environments. Without exception, the Kayin N5 can also be connected to a computer for use as a USB DAC . Its support for PCM 192kHz/24bit and DSD64/128 decoding strength is still worthy of recognition.


| Subjective sense of hearing

The experience of the listening experience is mainly based on the frequently-understood beyerar T51P , iron triangle MSR7, and dinars DN2000. The follow-up author is actually very much looking forward to using the HD600 to collaborate . Push down the classical plaque.

The existing several headsets, whether it is re-analytic reduction, or heavy sense of resilience, Kaiyin N5 can still be more accurate in place to show the design features of several headphones. The overall tone performance may be due to the desire to please most of the country's ears, or there is a certain adjustment adjustments, so the tone of the subtle existence of a very easy way. In addition, because they are all small impedance headphones, although according to the different performance of the ring iron unit and the tuning orientation of the headphones themselves, the use of the gain is still more cautious. As the saying goes, the icing on the cake is better, and more will be added. Become " joyful paste", in the author's view usually use N5 songs to basically honestly choose low-gain mode is sufficient.


The overall performance of the tri-band is more balanced, but it is more focused on the truth. The N5 's low-frequency interpretation is more circumstantial. In summary, it is full and mellow, wide-mouthed and powerful, but the high-frequency performance is Relatively satisfactory, sound is not clear and melodious.


It is said that N5 is a good player to listen to pop music. In the course of the author's verification, it is found that because N5 midrange vocals are relatively frontier, and at the same time excellent performance in terms of low-frequency sensation, the image creation capability has been increased. Stronger pop music, including rock and jazz, is indeed more rendering power.


| Horizontal comparison

There are horizontal contrasts that may allow us to understand more intuitively the KYIN N5 . This time, the author also has a certain reason by using the Fiio X5K, which is currently selling at a price of RMB 2,000 .

First of all, the price of the two players are using a 2.4 inch 400360 pixel display, followed by the digital architecture in addition to the DAC and the amplification chip, the JZ4760B+SA2000 master chip combination used is exactly the same, of course, flying proud X5K used The decoding op amp is TI 's PCM1792A+PGA2311A combo, and the corresponding configuration of N5 has been mentioned before and is not described here. In addition, DSD's native hardware decoding capabilities are basically inconsistent with the average consumer's experience.


The final Kai N5 and flying proud X5K contrast, slightly inferior is the volume control, and not as good as X5K 's integrated CNC process, of course, N5 overall looks more grade; and the system's fluency and deep standby life is still necessary to fly Pride for reference. For the difference in the sense of hearing performance, the author believes that the lack of N5 is the control of the bottom noise, the comprehensive hearing sense, and the details of the reduction is less than X5K is resistant; but the advantage of N5 is to listen to vocal full of warm heart, rich low-frequency atmosphere The feeling of bringing in is stronger, and one ear is lovable. Then there is no place for thrust.


| Conclusion

Although the time to start the Kaiyin N5 experience is not long, it is very much appreciated for such a less elaborate but sincerely full-hearted mid-range country brick. In my opinion, the N5 has retained the Spartan Kaiyin. Family sound features, and from the outside to the inside of the details of the modification, the appearance of color than the previous Tucao less obtrusive, and more lightweight and lightweight in return for better portability, of course, good hardware configuration and The right price positioning is the key, and it is also easier for pre-fired users to pay for orders.

For the comprehensive performance of auditory sense, the overall tuning style of Kaiyin N5 is still attributed to the warmer style. Of course, this is also the preferred orientation of most Chinese people. Balanced and full of people's sense of hearing, especially among the performance of popular vocals and jazz rock, it is worth mentioning that the thrust of Kai N5 is indeed extraordinary, before listening to several players like to open To 60% of the volume of the author, this time in the N5 even if the low-gain mode is only open to 40% volume is enough to wash the ear, which also makes the author planted as soon as possible for large impedance headphones to test the water power. In general, the Kaiyin N5 in the 2,000 yuan price comparison of the national tile, industrial ID and handling are not top-notch, but in terms of tuning is still more distinctive, it can be considered a representative of the strength to send a class.
