Summary & Objective:

The @Shanling M6 Pro (21) is the newest release of the Shanling M6 Pro line in July 2021. This time on it addresses some of the limitations of the previous generation players and also comes with a plethora of connectivity options. More importantly, this is the 1st Shanling coming with Dual ESS Sabre ES9068AS DAC chips shifting away from the AKM chips. Obviously, like all newer generation releases it promises better sound performance.

Tracks Used:
The tracks I have used can be found from the below playlist that I have used and generally use for most reviews...




Shanling M6 PRO (21) Sound Impressions in Short:

The BASS:


The Bass sounds just great. has enough details and is able to produce enough attack in the mid base region as well. In tracks like : "Anna R. Chie (Remastered) - Konstantin Wecker" and "Dreams (2001 Remaster) – Fleetwood Mac" you can feel the the deep attack of the different instruments with just enough details. The thumps and slams are very enjoyable.

The MIDS:

The Midrange really just excels in terms of every single element. It is able to produce an good creamy smooth and textured midrange that is soothing to the ears while having enough details in it. The vocals are natural and both male and female vocals come with good amount of details. Instruments sounded natural. In tracks like: "Anchor - Trace Bundy" and "Ruby Tuesday - Franco Battiato" while you will love the overall midrange specially transients of the guitars, violins etc... instruments and the vocals.

The TREBLE:

Though some people may complain the ESS DAC chip being a bit bright signature specially in the Treble region - this implementation is just great and seemed quite the reference grade. Hence, the treble just sounded nice and full and without any unwanted peaky-ness.

STAGING & RESOLUTION:

The staging and resolution is just great and just the amount the track requires. Nothing artificial here. Tracks like: “ She Don't Know – Melody Gardot” or “Bohemian Rhapsody (live aid) – Queen” sound good & enjoyable. Resolution however seemed very average and was not a strong trait.

Pairing:
The best pairing experiences I have found are with slightly warmer or reference grade IEMs. Unlike some other ESS DAC implementations, this doesn't have the tendency to increase peaky-ness when paired with bright IEMs.

Combinations:
Apart from the usual pairing with IEMs and headphones, 1 pairing that had stood out for me and I have loved a lot is it's pairing with the @iFi audio Micro iDSD Signature DAC/AMP. when paired with this portable DAC/AMP - it enables a lot more power than the Shanling M6 pro (21) can usually drive and hence makes it a .great combination for driving power hungry IEMs and Headphones.

Comparisons:

Though I do not have any other player in similar price range - I though it would be best to compare it against cayin N3 pro priced at $480 which is slightly lower price range and the cayin doesn't support streaming.

1648910216703.png


Shanling M6 Pro (21) vs Cayin N3 pro:

Build quality:
Both DAPs come in great build quality and has premium looks.
OS & Streaming capabilities: While Shanling M6 Pro (21) comes with Android OS and supports streaming apps, the caying N3 pro runs it's own proprietary OS and doesn't support streaming

Features & Amplification: The Cayin N3 pro comes with the unique feature of Dual Timbre through tubes which is not present in the Shanling M6 pro (21). However, the M6 Pro (21) has a plethora of connectivity features and ports that include all 3 popular ports of 2.5mm, 3.5mm and &44.mm are supported whereas the N3 pro supports only 3.5mm & 4.4mm and for tubes only 3.5mm

Sound performance: The N3 Pro comes with single AKM DAC chip, whereas the M6 pro (21) comes with DUAL ESS DAC chips. apart from that the M6 pro (21) has neutral reference grade tuning whereas the N3 pro comes with slightly warmer sound. both are perfect based on the preferences and pairings on different occasions. The M6 pro (21) outclasses the N3 pro in terms of amplification and power output capabilities.

Conclusion :

The superb performance of the Shanling M6 Pro (21) makes it an easy recommendation to anyone who is looking for a Streaming Android player below $800 range.

Awesome review I love my Shanling M6 pro 21 the only reason I don’t recommend it a lot is due to android 7.1. Wish it was upgradable to android 9 but it is what it is.
