Shanling M6 Pro Review

Shanling M6 Pro

Specifications

 

 

For the nit-pickers and nerdy ones here, I’m giving the specs and technical sheets. For all the others, you can just go to the next page to see how the DAP performs.

DAC and LPF

The Shanling M6 Pro uses two AKM AK4497EQ, a chip found in a wide variety player or DAC already.

It’s a popular one, found within the FiiO M11 Pro for example or Astell&Kern’s SP1000M. Asahi Kasei issued the chip with Velvet Sound Technology and advertised a 131dB SNR in balanced mode. Also, the Shanling M6 Pro offers full decoding of PCM files up to 32bits/768kHz.

To do so, Shanling implemented two Japanese KDS low phase noise active crystal oscillators, and an FPGA chipset to ensure bit-perfect decoding.

The brand says that each additional component was chosen very carefully :

  • white copper shielding on top of the audio circuit,
  • four TI OP1662 for low-pas filtering
  • four ADA4610-2 + four BUF634 for the balanced output amplification

The capacitors are provided by ELNA and Panasonic, two Japanese firms well-known for the quality of their products., If you can find some of them in high-end gear such as Accuphase, you’ll be glad to know that Shanling kept the four Selmic II capacitors and Tantalum Polymer.

In single-ended mode, separation is announced at 75dB@32ohms. But, in balanced mode, the separation reaches new heights, 109dB@32ohms, a whopping difference. Otherwise, Dynamic range and SNR are quite similar, with a small 1dB variation.

Power output is now rated at 200mW@32ohms in single-ended mode, and triple up to 600mW@32ohms in balanced mode. So, again, I’d strongly suggest that you use the Shanling M6 Pro through its balanced outputs.

A nerdy guy with a passion for audio and gadgets, he likes to combine his DAC and his swiss knife. Even after more than 10 years of experience, Nanotechnos still collects all gear he gets, even his first MPMAN MP3 player. He likes spreadsheets, technical specs and all this amazing(ly boring) numbers. But most of all, he loves music: electro, classical, dubstep, Debussy : the daily playlist.

      Thank you for the detail review NanoTechnos. It is quite informative.
      M6 Pro is an interesting player.
      May I ask you the definition of dry sound? I am to the hobby.

      I am evaluating whether to get Shanling M6PRO, Cayni N6 Mark II (the most color sound)
      or iBasso DX 220. I believe they all have somewhat different sound signature. Shanling seems to be slightly color to my sound preference (neutral but slightly boosted bass and elevated treble).

      I originally thought about getting the iBasso DX 220 but worry about the software implementation which is not as smooth as the other two based on the review.

      I look forward to your feedback.

      Great review! Any chance you could compare M6 Pro with Dethonray DTR1 and QLS QA361 in terms of sound?

      I plan to get m6 pro or astell & kern SR25. Today I have a chance to try both of it with two different earphone, Custom IEM and custom 4 driver tuned earphone. I love both DAP but surprisingly in different ways.

      M6 pro with IEM (balance), it feels dry and neutral. Good dynamic range and layer separation. Sound stage on wide site. Nice impact and feels the rumble. Vocal up front. Crisp but not sharp.

      M6 pro with tuned earphone (unbalance), not dry but neutral. More dynamic, more width and fullness sound. Nice wide sound stage. Crispier and very fun to listen.

      In other hand on SR25 make me confusing to decide.

      SR25 with IEM (balance), Fullness of sound. Great dynamic and layering. Wide sound stage. Nice impact but not as good as M6 pro. Good clear vocal tone. High crisp and clear. Very fun to listen.

      SR25 pro with tuned earphone (unbalance), flat and neutral with good dynamic. Good sounding overall but I didnt feel excite compare with pairing on IEM.

      By my taste, i like M6 pro with tuned earphone (unbalance) and SR25 with IEM (balance) both combination make me very excite but in different way. This make me very confuse to pick up one.

      I want to hear your opinion. Comparing M6 pro and SR25 in sound wise.
