Born Like Summer Flowers-Feiao M11 Plus LTD Experience Sharing

:

AK4497EQ decoding chips, which were once "all-powerful" in portable players and desktop decoders, were forced to stop production after AKM suffered a serious fire. Under the background of "lack of decoding chips" industry, Feiao's dual AK4497EQ player M11 Plus LTD is undoubtedly more touching than in the past.

-Abandoning the traditional scroll wheel design and adopting a touch and key integrated volume panel, the interaction mode is obviously different from the previous generation products;

-equipped with Qualcomm 660 master control, RAM up to 4G, Android 10 system, the overall operation is very smooth;

-The decoding part is equipped with double AK4497EQ chips, and the earpiece part uses THX AAA-78 module. The sound is pure and there is no obvious sound dyeing. The effect of deducing music is very vivid;

-has good driving force and can provide good matching effect for earplugs of different unit types.

[Barren Soil: Dilemma of Decoding Chip]]

came into contact with HiFi, they naturally learned a lot of audio knowledge and also came into contact with some controversial views. For example, in the field of players, many people have been arguing for a long time: does the decoding chip determine the sound of the player?

I have never been a "core-only" person. As a graduate of physics major, I know that the decoding circuit module built around DAC also plays an important role. But even so, I can't ignore the distinctive features of today's mainstream DAC chips. In fact, the current player has little choice in the use of DAC, and if a chip can ensure that the parameters are up to standard and the designer can bring up various sounds, then this chip is very successful in HiFi circle.

the scene of a hundred flowers blooming in the field of portable players has also benefited to some extent from the support of good DAC, such as the AK4497EQ of AKM. This chip can easily balance the quality and charm of the player. It has been used in many portable players and desktop equipment for many years. Even if AKM's current flagship chip AK4499EQ has been available for a long time, the fans have not forgotten the voice of the previous flagship.

However, after the AKM fire accident last year, AK4497EQ lost more than half of its inventory. This year AKM directly announced that AK4497EQ will stop production, and this classic decoding chip will soon be out of print. Therefore, when Feiao announced the information that the new player M11 Plus LTD (hereinafter referred to as "M11 Plus") will be equipped with double AK4497EQ, many fans who are familiar with the industry news felt incredible.

Feiao M11 series of players, I have been in contact with them since they came out. The first M11 player was born during the adjustment period of Feiao player sequence. This product inherited the excellent tradition of earlier players in design and interaction. The sound performance was put on the 3,000-yuan file at that time, which made people unable to find anything wrong. The sound level of the second device M11 Pro is significantly higher than that of M11. Its balanced and neutral sound style and sufficient driving force can accurately reflect the sound trend of earplugs. The M11 Pro has therefore become a reference front end for me to test the performance of earplugs for quite a long time.

Based on the good memories and use experience of the previous two generations of players, I am naturally full of expectations for the series sequel. As soon as the news that AK4497EQ was about to go out of print was released, my expectation was mixed with some uneasiness: what impact will the turmoil in the industry have on this machine?

with a complicated mood, I opened the M11 Plus express box......

[budding: unpacking and operating experience]]

M11 Plus is the same as that of Feiao's previous player products: black bottom is the keynote, and the outer box covers the image of the float player. Open the box cover and the machine will be visible. However, the M11 Plus has been put on the attached black leather case when it leaves the factory, and the protection is in place. Other accessories mainly include data lines, coaxial adapter lines, pins, etc.

holster faces below the fuselage. Remove the holster and the true face of M11 Plus is in sight. Generally speaking,M11 Plus is quite similar to that of M11 Pro. It is based on a square cuboid, and the edges on the left and right sides are cut in three dimensions.. However, in order to adapt to the new volume interaction system, the cutting lines of M11 Plus go straight and straight, which is less flexible and more dignified in visual effect.

is that M11 Plus uses Feiao's new intelligent volume interaction system.M11 Plus abandoned the long-standing volume wheel design of Feiao Player and changed it to an integrated volume panel with touch and keys. Users can either slide the panel to quickly adjust the volume or press the keys to adjust carefully., however, in terms of my personal actual experience, the area of the touch panel is a bit large, and the sensitivity of the panel is also relatively high. Sometimes the machine is placed on the desktop and will accidentally touch it with a hand, which is more difficult to completely avoid. In the M11 Plus system settings, the option of automatic panel locking is also provided. Although there will be one more step when unlocking, it is still more important for my daily use.

All buttons on the M11 Plus body are designed as a honeycomb regular hexagon. The upper part of the volume panel on the left side of the fuselage is the power key, and the lower part is the multi-function key that can be customized. On the right is the three keys of up and down bending and pause, as well as the key lock switch and TF card slot. The top of the fuselage is flat, while the bottom is 4.4 balanced, 2.5 balanced, Type-C charging port and 3.5 single port lined up along the center line. The back of the fuselage is designed as a diamond-like cutting texture, and different tilt angles reflect different light effects, which is quite beautiful.

The layout of all keys in M11 Plus has many changes compared with M11 Pro. In practice, I thinkin the case of one-handed operation with the right hand, M11 Plus places more emphasis on the coordination of thumb and index finger. In addition, M11 Plus has a girth size of 136.6mm * 75.7mm * 17.6mm, and its length and width are 5 and 6mm more than M11 Pro, thus reducing its portability and grip. For me who is used to M11 Pro, it still takes some time to adapt to the changes in interaction mode and volume.

if there is a subjective difference between likes and dislikes in the change of design language, then the hardware upgrade is real. M11 Plus master was upgraded from Orion 7872 to Xiaolong 660,RAM was upgraded to 4G, and the operating system was also upgraded to Android 10. The overall operation was very smooth and the support for APP was better. The display effect of the 5.5-inch screen is delicate and bright. The 6000mAh battery is enough to support single-ended and balanced to reach about 11 hours and 9 hours of battery life respectively, basically reaching the level of one charge per day. Judging from all aspects, the use experience of M11 Plus is generally satisfactory.

[Flower Shadow: Sound Performance Test]]

M11 Plus uses the decoding configuration of M11 Pro dual AK4497EQ, and its significance is unnecessary. In the earpiece, M11 Plus uses the highest-end module THX AAA-78 in the THX AAA Frontier series. Its feedforward error correction technology and "achromatic" sound-free dye amplifier architecture can truly restore the sound of each frequency band. Analog circuits and digital circuits are isolated from each other, and shielding covers are added to each module circuit to reduce the interference between digital and radio frequency and improve sound purity.

of course, whether feelings and technology can once again bring classic voices to burn friends needs to be tasted by burn friends. In this audition of M11 Plus, I used Feiduo Artemis as the main earplug for audition and M11 Pro as a reference to listen to what different feelings the new player will bring me.

first auditioned the single-ended output of M11 Plus.

from the first note,M11 Plus has always brought me a lively sense of listening.. The sound of this machine is relatively fresh. No matter what kind of music you listen to, it implies a kind of exhaling emotion.M11 Plus has a relatively positive tone, and there is no particularly obvious tone on the whole., rely solely on this vitality to mobilize the listener's mood.

in terms of quality, M11 Plus inherits the characteristics of Feiao "bucket machine" in the past., the overall performance is quite good. This "bucket" has a relatively long "board"--sound field: the whole is round, the arrangement of music elements is quite regular, the sound hierarchy is also very in place, and the sound boundary is not obvious. For example, when listening to Tchaikovsky's "Symphony No. 4", the far and near effects of different instruments can be well restored. In other dimensions of quality performance, the dynamic performance can be described as surging, enough to make the listener feel the momentum of the symphony scene; the transient response speed is faster; the analytical performance is also very delicate.the quality of M11 Plus, it is quite competitive at a price of 5,000 yuan.

and inIn terms of three frequencies, the distribution of M11 Plus and M11 Pro is relatively similar, and both are in an overall equilibrium situation.. However, the performance of each part of the fine product can easily distinguish the difference between the two machines.

low frequency, M11 Plus is slightly heavier than M11 Pro by two or three points.the low frequency of M11 Pro gives me the feeling of moderate strength and not slow, while M11 Plus starts to make me feel the strength of hitting deep in my ears, with a little resilience and more tight rhythm. Moreover, the low-frequency diving depth of the two machines is basically the same. Take "Umbrella", which is a collaboration between Rihanna and Jay-Z, as an example. The low-frequency sound effects that run through the whole song are important elements in this pop music to promote emotional development. Compared with the straightforward narration of M11 Pro, the low frequency of M11 Plus is even more tense. From Jay-Z rap to Rihanna singing, the low-frequency synthesizer sound effect and bass step by step, allowing the listener to integrate into the mood of the music from beginning to end.

In terms of intermediate frequency, the density of M11 Plus is slightly higher than that of M11 Pro, and it is still balanced in the overall structure of three frequencies., it will not appear abrupt. The positions of the two robot sounds are relatively close,M11 Plus's vocals are more straightforward and penetrating. For example, when listening to Eva's Cassidy "Autumn Leaves", M11 Pro is dedicated to showing the characteristics of the singer's breath using the strong and weak conversion, while the singer's voice is slightly thicker under the interpretation of M11 Plus. Eva Cassidy has a deep singing skills. If it is replaced by a singer who does not use enough gas, M11 Plus will undoubtedly be able to form a little supplement to his voice, making the voice more ear-catching.

andfor high frequency, the brightness performance of the two machines is similar, but the hearing feeling of M11 Plus is obviously smoother and more malleable than M11 Pro.. For example, many Paganini works in "Diabolus In Musica" played by Accardo, M11 Plus is more complete in the details of the performance process, and the listening feeling is clear. Musical instruments such as violin and triangle iron have received good interpretation of high-frequency overtones, and the effect is very attractive.

on the whole, the performance of M11 Plus triple band has a subtle change compared with M11 Pro. Personally, I prefer the high and low frequency performance of M11 Plus, while I prefer the natural degree of M11 Pro in terms of intermediate frequency. If I were to be more critical, I would think that the coordination between the M11 Plus frequency bands can be stronger to obtain a higher degree of harmony in overall performance-of course, at this point, I think this is more of a style trade-off problem.

, if you consider the degree of listening, M11 Plus is better than M11 Pro. For burn friends, it is enough for M11 Pro to provide the sound of peace and justice. M11 Plus shows a more vivid sound style while maintaining balance. At the mid-range price of 5,000 yuan, this style is undoubtedly popular with burn friends.

change the headset to the balance port of M11 Plus to continue the audition.The driving force of the balance port is greatly improved compared with that of a single port., after adjusting the volume to an approximate level of sound pressure, it can be found that,M11 Plus is not far from single-ended in style, and the low-frequency overtones are slightly more than single-port, but not too much. The quality performance of the balance port is higher than that of a single port. The more obvious part is that the shaping of the sense of space is more profound and the sound density is further improved.for some earplugs that are not easy to drive or have high potential, the balance port of M11 Plus can give full play to its strength.

[Flowers and Leaves: Earplug Matching and Style Adaptability]]

In addition to flying Artemis, I also chose Zen of Dayinke and EJ09 of Shuoer to match the audition.

Zen is a single-acting coil configuration. The overall style is natural and calm. The replaceable plug design also allows me to compare the performance of single-ended and balanced more intuitively. When connecting the M11 Plus single port, the regular sound field in Zen's quality is most obvious, but the overall hearing feeling is slightly "unable to open. When changing to the balance, Zen's voice was suddenly enlightened, and the resolution was also improved to a certain extent; the vocals that originally appeared to be behind moved a little forward, and the knots of various musical elements became more compact. It can be said that,the balance port of M11 Plus is relatively more able to tap the potential of Zen. The interesting thing about this match is that,M11 Plus forms a complementary relationship with Zen, and the final sound also forms a certain balance..

EJ09 is a ring iron static composite unit earplug, with excellent comprehensive quality and certain requirements for front-end control. When this plug is connected to the M11 Plus single port, the sound background is relatively pure, the excellent expressiveness of the middle and upper plates has good play, the details are dense, the knot is detailed, and the overall listening feeling is relatively delicate. When changing to the balance port, the low-frequency sense of quantity is supplemented a little, the density of the intermediate frequency is also increased, and the whole sound structure is more robust.The driving effect of M11 Plus on EJ09 is remarkable regardless of single-ended and balanced., and I personally prefer the light stretch sound of single-port drive.

Regarding the adaptability of M11 Plus, I thinkits more positive sound style itself is well inclusive, it is especially suitable to interpret music types such as vocal pop, rock and even hip-hop.. However, M11 Plus's interpretation of music has some "refreshing feeling". For some music that needs to be tasted carefully, such as some pop music and blues music with deep style, the sound characteristics of M11 Plus may give the listener a sense of "wrong taste. Of course, it also depends on the personal preferences of the burning friends.

[Last Brilliance]]

to rough numbers, among the new products in the HiFi portable player field this year, except for the models whose DAC research and development route is not originally AKM direction, the rest are either forced to transfer the research and development route or rely on a very limited number of chip stocks to support the listing of the new products. Either way, it is full of unprecedented difficulties in the industry.

in such a market, Feiao still polished out such a high-level AK4497EQ player, which once again makes people sigh its strong resource reserve and poisonous strategic vision as a leading enterprise in the industry. What is more worth mentioning is that under the premise that the chip is out of print and has no market price, M11 Plus, which has fully upgraded hardware configuration such as master control, RAM, display screen and audio circuit, still maintains the price level of the previous work, which is quite rare. On a certain level, M11 Plus is a big gift given by Feiao to advanced enthusiasts in 2021. Whether it is Feiao's old users or users of other brands before, M11 Plus can undoubtedly be regarded as a considerable priority when considering changing planes.

of course, even if there were a certain amount of chips in the previous inventory, the "landlord's surplus grain" would one day be exhausted. It can be predicted that the product cycle of M11 Plus will be very short, which also makes me feel the "untimely" of this machine during the audition of M11 Plus-if there is no black swan incident in the industry, this machine may become another evergreen model.

this year, every player with a AK4497EQ chip is a masterpiece of this classic chip. In this summer, in the last days of AK4497EQ "life", M11 Plus used a gorgeous way like summer flowers to rejuvenate this classic chip and keep its voice in the memory of burning friends.
