is pure but not pure-Feiao Q5S AM3D

"Cancel Headphone Hole 」

Since Apple brought this good head, no matter how much your consumers oppose it, various mobile phone manufacturers have followed suit as usual. It seems that overnight, the concept of mobile phone HiFi has been submerged under the wheel of history. Although this small change has brought trouble to users, it has brought new ideas and opportunities to the market. In order to cope with the dissatisfaction of picky enthusiasts with the sound quality of the official patch cord, the industry has given two directions-decoding patch cord & Bluetooth receiver. Let's not talk about the decoding line today. I 've played a lot of Bluetooth receivers. From Astell & Kern's XB10 to Feiao's BTR1, μ, 1K, 3, Iron Triangle's PHA55BT, as well as cross-border Shanling M0, Haibei R3 and Feiao M5, I have been in my hands for a long time. It can be said that I have witnessed the development of Bluetooth receivers all the way.

Today, let's talk about Fiio Q5s, the only flagship portable Bluetooth receiver/decoding earpiece on the market. (hugo2 does not count, the goods are delivered by Bluetooth)

Benefit-related: provided by Q5s manufacturer and purchased by AM3D module.

design:

On the day I got Q5s, I also sent a circle of friends [the first feeling of Q5s was exquisite]]

one-piece CNC metal shell is formed, and the wire drawing process and sand blasting process are applied to a piece of aluminum at the same time. This is the first time I have seen it on a domestic earpiece.

pure linear design, metal primary colors, high-gloss chamfer, no extra decoration, the whole gives Q5s German-style industrial texture, which is still very good for my kind of engineering straight man's taste.

is a piece of PU imitation leather, which not only plays an embellishing role, but also plays a good anti-skid role when holding or placing it on the desktop. It can also prevent scratching when binding mobile phones or other turntables, just hoping that there will be no glue problem...

, I would like to mention Q5s lamps in particular, which should be inherited from X7 and Q5. I have always been quite afraid of domestic manufacturers adding lights, because once they are not handled properly, they will appear vulgar and even dazzling. However, Feiao's treatment is very clever. First of all, the position of the lamp is at the joint between the main body and the module. It is a hidden design and will not destroy the integrity of the appearance when it is not bright. Secondly, it is a uniform strip of light, the brightness and saturation are not high, and it looks very low-key and elegant. Finally, it not only has a decorative effect, but also can display the working mode and input sampling rate in different colors. The design similar to Chord is very intuitive.

The top is line/fiber/coaxial composite input, line output interface, low frequency gain switch and gain selection switch. There are playback control, input selection and volume knobs on both sides.

standard AM3E is 3.5mm single-ended PO, 2.5mm & 4.4mm balanced output, and Micro USB charging/data interface. (AM3D is one 2.5 less)

The only regret in the design is that the USB Type-C is not used, which may be due to the consideration of accessory compatibility, but this means that one more cable will be brought when going out...

function:

My evaluation of its function is written in the title:"Pure but not pure 」

It is purely because Feiao still insists on making a simple flagship portable decoding ear at a stage when the portable ear is declining and the portable player is becoming more and more fancy. It is simple and direct. There is no screen and Android system that affects the sound quality in HIFI fundamentalism. There is no R2R architecture and electron tube amplification with gimmicks greater than meaning. There is no gold plating or limited amount of money. The duty makes people believe that this is a domestic HIFI.

But as a portable decoding ear, its function is not as single as MOJO. Q5s not only has a complete input method, can be connected to various turntables, but also has a full format Bluetooth reception CSR8675 blessing. In terms of the core capability of decoding and amplification, it is also a rare portable front end that can be used as both Line Out for pure decoding and Line In for pure earpiece. It can be flexibly combined with various split equipment. Moreover, Q5s retains the design of interchangeable modules, is compatible with all the ear modules of Feiao, and directly becomes the cheapest THX AAA architecture ear amplifier at present by matching AM3D. How strong is THX AAA? Those who have used it Massdrop 789 understand that I will elaborate on the sound quality part behind this. Because of the AK4493EQ, you can even set up six filter modes and ten-segment equalizer in Feiao Music App, which is the first time I have seen it on a portable decoding ear without a screen... There are also some detailed functions, such as BassBoost, MFI authentication, Bluetooth control of mobile phone, digital volume adjustment knob, etc., which are all excellent traditions inherited from Feiao's previous products. Everyone is familiar with them, so I won't be wordy.

If you insist on finding the problem of Q5s, I think there are two. One is that the heat is obvious when the balance mouth is used at a large volume. Although it is not as exaggerated as MOJO, it is still quite hot in your pocket in summer. The other is that I personally feel that the BassBoost effect is a little too much. Although the low frequency sense has doubled, it has obvious influence on the intermediate frequency. If the firmware update can reduce the amount of low frequency in the future.

Generally speaking, Q5s has achieved all the functions that a decoding earpiece should do, and has been designed as the only flagship Bluetooth decoding device in the market by its unique Bluetooth capability and module, and there is no competition.

for me personally, it is more in line with my needs than the M11 I use everyday.

because I don't listen to local music outside and only use AppleMusic. On the one hand, M11 does not support AAC reception and IOS DAC (Android pot), and on the other hand, it does not support installation AppleMusic (or Android pot...), which forces me to use hot Airplay on my mobile phone, which is very expensive and exaggerated. The Q5s is very suitable for my needs. The sound quality under Bluetooth AAC is almost the same as that of Apple cable, and there is almost no delay. In addition, the volume is smaller than M11, and the endurance is also very strong. I basically take this product with me when I go out now, which is very easy to use.

sound quality:

Q5s uses the XMOS CSR8675 dual AK4493EQ scheme. I don't know if it has the same structure as M11, but the sound quality of the two is basically the same and the tuning is different. They are the top level in the portable front end except for the sky-high price of the 4497.

Q5s is a more popular tuning style. The low frequency is very solid and plump, which is more quantitative than M11, giving the whole a very relaxed and warm tone. The intermediate frequency converges slightly, the human voice is not attached to the ear but not stained, the intermediate frequency details are rich and condensed, and the information and dynamics of the typical double DAC have no obvious tendency. The high frequency performs well in the wired mode, without exaggerated extension, but it is bright and clear enough, and the details and body are relatively plump. There is a slight roll-off in Bluetooth mode, which is a short board of Bluetooth coding.

Under the standard AM3E module, although the decoded information has been explained in 150, I always feel that the sound is relatively flat, and the sense of scale and dynamics are relatively formal.

After listening to it for a while, I always felt that this should not be the full strength of this decoding, so I tried to connect Aune X7s with LineOut. Sure enough, under X7s, the sound became very three-dimensional, the whole knot image was pulled apart, the dynamics became stretched, and the sound was more smooth and smooth.

Therefore, I think AM3E has limited the quality of this product to a certain extent. After implying that Mrs. Ma's attempt to go to white prostitution failed, I directly placed an AM3D order on JD.com.

Here is a brief mention of why I bought AM3D ~

Because AM3D is an ear module of THX AAA architecture. THX AAA series is a newly developed amplifier design by industry giant THX. It uses a design combining the main amplifier circuit with the front feedback error correction auxiliary amplifier circuit. Whether it is output power or SNR, THD, IMD, Crosstalk and other indicators, it is extremely high. I have heard of the Massdrop THX AAA-789 before and used the top amplification chip in AAA-789 series. The quality is ridiculously high, almost completely 0 dyeing, extremely clean, transparent, bright and delicate sound, and exaggerated 6000mw output power under 32 Ω... I have always thought that this product is the strongest single-ear amplifier I have ever heard, but because it is too difficult to buy in China, I have never started.

Therefore, I am very interested in seeing Feiao's AM3D with mobile AA-78 chips. However, M11 cannot change the module (it is said that M11pro has changed the THX earring module), so there has been no plan to buy it. This is just right. Q5s AM3D should be the cheapest THX scheme at present.

Although AM3D uses two mobile AA78, the sound style and quality are the same as the THX family. Compared with the traditional AM3E, one ear can obviously feel the difference: the background is extremely dark, the low frequency dive is deeper, the intermediate frequency is almost a straight line, without any staining. The decline of the overall distortion makes the sound much more transparent, the sense of space is larger, and the dynamics are smooth and atmospheric. It can be said that AM3D has fully played the sound level that Q5s should have.

Although the output power of 550mw under 4.4 port 32 Ω is not as exaggerated as 789, it is more than enough to push most headphones. The size Z1R in my hand is pushed to a full blood state, and HD800 can also push out a certain thickness and dynamics.

Compared with our own M11, the quality of the two modules under the standard module is almost the same. M11 tuning is colder and thinner, suitable for instrumental vocals, and Q5s tuning is warmer and thicker, suitable for popularity. The Q5s earpiece under AM3D has advantages, with stronger purity and control.

--------------------

Q5s, as one of the few decoding earphones in the market, with its unique Bluetooth capability and excellent sound quality, obviously surpasses the older generation of PHA-3 and MOJO under the matching of AM3D. Q5s has not only become my daily front end, but also my most recommended portable earphones at present.
