  • The Shanling M6 is equipped with OPA 1612 Low pass filters while the M6 Pro version comes equipped with OPA 1622 Low pass filters along, the whole circuit includes premium-grade four low pass filters providing the users with a much cleaner and powerful sound output.
  • Lastly, With better decoding and amplification the M6 pro reproduces a much more detailed and lively sound output.

Unboxing Impressions

The Packaging was fairly convincing. If you open the box you will be greeted by the following things.

  • Player
  • 1 USB Type C charging cable
  • Manual
  • Warranty Card
  • Screen protector

Build of Shanling M6 Pro

The main difference with the M6 ​​is the material. Technically it’s the 5th edition design of Shanling. However, the new generation of M6 Pro comes with the power of symmetrical aesthetics. It doesn’t have the original mountain-like R corner of the original M6, the sides of the border form symmetry, and the “R corner” design is moved to the upper right corner of the screen. Although the opening of the bezel and the button layout are consistent, the M6 ​​Pro is slightly shorter in height than the M6 ​​in the wheel button part, or it shrinks a little inside the bezel. The guess maybe to further enhance the durability of the button.

The back is where the M6 ​​Pro has changed a lot. Shanling first integrated the process of AG matte sand erosion into the design of the product. This makes the back of the M6 ​​Pro, form a richer level transition, and this transition includes both visual and tactile, and also quickly brings key information such as brand logos and product models into the user’s sight. Individuals are also very pleased with this design element.

User Interface

M6 pro gets power from Snapdragon 430 Processor chipset and 4GB RAM+32GB ROM. So, the user interface is very quick and smooth, even with about 4000 FLAC songs loaded into the memory card the transitions are smooth and crisp. The cover arts load quickly, with no lag and no software issues.

The Shanling M6 pro runs Android straight out of the box which also enables us to use different streaming apps on the player.

Android Music Player

It is a double-edged sword to install Android on professional players. Firstly, it can greatly increase the customization and scalability of the DAP, and it has more freedom and better performance of UI; with the ability of network connection. Plus we are getting cloud music playback. But from the other side of the blade, Android’s “not paying attention” to the audio subsystem design will obviously reduce the sound quality, so that it can’t create a machine that will not “sound” the sound.

Shanling’s approach to Android’s audio problem

ShanLing RD specially developed AGLO (Android Global Lossless Output) Android global lossless audio framework. However, I am not interested in these bells and whistles, I only care about the specific implementation. According to the official introduction, it is probably done like this. App’s audio digital stream output is exclusive. It bypasses other audio mixing output. So, only one app can monopolize audio output at the same time, regardless of mixing, no sampling rate is converted at the HAL. It will not happen in SRC. Certainly, they customized the FPGA to process the audio signal separately and cooperated with the high-precision clock signal generated by the double crystal oscillator to transmit the audio stream to the two AK4497EQ DACs at the back. Thus, they are confident about their Audio output process.

Shanling M6 Pro’s Sound Quality

Whenever we are buying a new Digital Audio Player, we always think about it’s pairing with our headphones/earphones. Mostly we think about its sound quality. But in the case of Shanling m6 pro, it sounds like a flagship player in its price range.

M6 Pro supports balanced + single-ended output and provides 3.5mm + 2.5mm + 4.4mm at the same time. The fully balanced output mode naturally binds two DACs. This is no surprise because everyone basically does this. However, the M6 ​​Pro plays more in the single-ended working mode, allowing single or two DACs to work; because the limit of the single-ended limit is lower than the balance, the benefits of the two DACs are not large; In some cases, it’s still useful to use a single DAC, but I’m curious why other manufacturers don’t do this? It’s actually quite interesting. In terms of the sense of hearing after the actual switching of the working mode, the sound density in the dual DAC mode is significantly enhanced, and the dynamics are also slightly fuller at both ends. There is no obvious difference in tone.

This time Shanling designed the analog part of M6 Pro more violently. The OP + BUF AMP architecture is very common. It also carries OPA 1662 for low-pass filtering, ADA4610-2 (OP) + BUF634 * 2 (BUF); cooperates with the two The AK4497EQ DAC and M6 Pro have very good acoustic qualities. From the official nominal data, they do have very beautiful performance indicators. Lastly, it needs more time to evaluate the actual detail of sound analysis. So, stay tuned for the final review of M6 pro.

Final Impressions

The Shanling m6 pro is actually a very brilliant flagship DAP with support for all the formats. Shanling M6 pro is a bit close to a “mid-end ruler” at a price of $700-800. Although it is The power, the single-end / balanced sound level, and the adaptability of the earplugs is versatile. it is for most audio lovers. Stay with us for more impressions and reviews.
