Original: Free Receiving and Receiving, Comprehensive Balance, Feiao M9 Trial
Feiao is deeply loved by Feiao fans after the launch of M7 and BTR3. Many enthusiasts can't help but imagine a combination of the advantages of both (full format Bluetooth take-all sending and receiving), coupled with X5III's open Android platform, sound quality advantages and powerful output interface, such a machine is difficult to think of without fire. Feiao people were obviously driven by this inspiration early on. They secretly brewed and followed BTR3, which is very hot in the market, to launch a comprehensive upgrade of M7. M9. Its design idea is the same as what I described, that is, it combines some advantages of M7,BTR3 and X5III, and skillfully combines them into one machine. In this way, wireless Bluetooth is played to the extreme, coupled with the Android platform network song ordering and comprehensive interface, M9 really makes players excited as soon as it comes out. "We are crazy and even we are afraid of ourselves," Fei Ao sighed when communicating with users on Weibo.
Feiao's products may not be the most exquisite in packaging, but their accessories are definitely the most abundant. Perhaps it is because Feiao people themselves are hardcore players who love machines. Feiao's products always leave the factory with film and protective covers. The M9 is no exception. Compared with M7, the key setting of M9 is also more reasonable, and the power key is finally set at the position with the volume and play control keys. The keys feel good. M9 has about 2G of built-in space for users to use, but I believe most users will definitely give it a large-capacity TF card.
The use of the Type C interface is also expected. Feiao even uses Type C on small machines like BTR3, M9 is more natural. Different from M7, in addition to ear output and Line Out, this 3.5mm interface also serves as coaxial output.
in my years of playing with computers, the sound quality of coaxial output is the best at present. It is warmer and more natural than optical fiber output, not to mention other connection methods. It should be said that M9 plus coaxial support is a very wise decision. Now there are more and more power amplifiers and active speakers supporting coaxial input, and coaxial interfaces are really useful. Feiao equipped M9 with a 3.5mm patch cord to lotus port. The coaxial line in my hand is thick and hard, and this small patch cord is still more practical. In addition, under coaxial output, it is very power-saving like Bluetooth output. In addition, M9 also introduces a balanced output (2.5mm) that can obtain better sound quality details, which is also a popular upgrade point. It can be said that Bluetooth is the first choice to pursue convenience first. M9 supports Bluetooth full format compatibility. In addition to the common aptX, aptX HD,LDAC (Android8 direct system supports Sony's LDAC) and other codes, it also supports the latest HWA. The compatibility of these Bluetooth codes can ensure the best balance of convenience and sound quality. If you want to be the first in sound quality, you can use coaxial output. Players with traditional earplugs can use 3.5mm earplugs; M9 has two built-in AK4490 DAC chips, which is also an excellent balance between M7 and X5III in sound quality performance. It supports high and low gain adjustment and can fit more earplugs. Compared with the old products, the Android platform makes the switching of various interfaces extremely convenient (the old products can only be changed if they exit to the home page and then enter the system settings). In terms of local playback, M9 supports DSD128 hardware solution, and directly supports ISO,DFF and DSF formats.
M9 also absorbed the beloved indicator light of BTR3. In addition to different codes in Bluetooth mode to display different colors, different colors can also be displayed according to different music formats when playing locally. For example, the most common ones are lossless music display purple, compressed music display blue, etc. This indicator also intuitively shows the working status of the machine, avoiding the embarrassment of wasting electricity playing behind the back without the user's knowledge. As for Feiao's "deep sleep", it must be blessed. The measured deep sleep standby of shutting down the network is quite good, about 2% a night.
on M7, although it is also based on Android, because the machine does not support Wifi, a major advantage of the Android platform cannot be reflected. M9 has built-in Wifi, and Feiao has also built-in several online music apps for M9, including Netease Cloud Music, which is very popular. Judging from the actual measurement, limited to the overall hardware and memory, the gap between fluency and speed and mainstream mobile phones is still obvious, but it is fully available. On-demand loading may be slightly slower, but stable. After all, the amount of music that can be installed on the TF card is still limited, and the support of network streaming media really gives M9 an infinite music library. The key is compared with mobile phones. In addition to full-format Bluetooth compatibility, it can also output coaxially. M9 also supports full format reception, the specific format depends on the audio source device. After receiving, it can still be output coaxially to obtain the best possible sound quality. However, as of the time of publication, there are still some minor bugs in Bluetooth reception that need to be corrected, and the corrected firmware will be released soon. This is very much to look forward. After all, as a sound source turntable, there is nothing more convenient and powerful than a mobile phone. The playability of M9 also includes USB Audio, USB DAC, etc. As a computer, it can also output audio in Bluetooth mode in USB DAC mode, providing more possibilities for practical use.
M7 is more than square, while M9 is rigid, flexible and balanced. The weight control of the whole machine is also very successful (133g), and the portability is good. What is slightly embarrassing is that because the keys are all on one side of the machine and the keys are very sensitive, it will cause the wrong operation of the keys when you carry them with you. Although the system setting can disable the button under the screen, it is also a painful choice between convenience and safety.
After these days of use, I can't help but sigh that M9 will directly threaten Feiao's own X5III?X5 earphones have stronger configuration and stronger Android openness (limited to hardware M9 only providing very limited openness), but after all, M9 can still be proud of being fully compatible with Bluetooth transceiver, with small difference in sound quality and no inferior interface. It is more playable for audio players, and perhaps many people will start to suffer from difficulty in choosing...
