I research in computer sciences and digital technology with focus on artificial intelligence. I mod and build headphones as a hobby because I am into perfection for that killer sound -- sound is my life and a major part of my salary I invest in audio. I refused DAPs because I believed that it is part of the past with great phones that can do the same. However, this
Shanling M0 Pro is a mega hit, it is fantastic. It is for those on the go and the best music device for us who work out. Shanling did it right and this is little light thing is my top recommendation.
I was tired of my dependence on a phone for music which gets in the way during workouts and very messy with cables when playing MQA in no-bluetooth mode. I longed for a very small DAP and therefore purchased and received a M0 Pro. This is the first Shanling product ever after experience with many desktop and portable DACS and amps such as those of Rega, Maranz, Denon, Khadas, Singxer, SMSL, ifi, and fiio. I do have Volumio 3 running on a Raspberry pi 4, a small player but no way I want to use it on the go, also there is no battery. I was considering getting a Rpi zero 2 with battery and a 3D printed case but it became too bulky with a poor screen. I found my optimal solution> a M0 Pro that costs less than trying to build my own player on a Rpi Zero. I hit the order button and forgot about Rpi. I have downloaded MQA files and yes -- wow, the M0 Pro appears to play them with no problem, the MQA logo lights up. Also, when I send the file to a MQA DAC through USB, the MQA logo lights up there as well, on external DACs such as SMSL D1SE and BTR7..... this might be an positive unexpected surprise that is not on Shanlings marketing of this little thing,
Sound Quality
I have quite musical ears but it is hard for me to describe the sound as many reviewers do: The sound is very good for a portable device but it is not at all a desktop replacement and sending M0 Pro USB out to a BTR7 you get better sound. The cross talk is minimized by a lovely balanced design with dual

and separate op amps.
Trying MQA playback
Q: Does it send MQA bit-perfect to the DAC so I may hear a complete unfolded MQA? Looks like it. So far I am happy with M0 pro..

. Test: on my Linux box, I downloaded and converted a Tidal MQA track from Utada Hikari album with my own developed program in python. I dont compress anything, I just dump it as a FLAC with all MQA preserved. The penalty is huge with file sizes of 50+ MB but I have plenty of space on my micro sd card that may be as large as 2 TB, yet mine is only 128 GB, still nooo problem. My program downloaded and converted files fast and accurately, however when copying to a micro SD card some files were copied with errors, which forces me to check files for errors and copy again.
My Usage
M0 Pro for use in workouts together with a MQA decoder such as a BTR7 or BTR5... having M0 Pro only as a player to transmit bit-perfect trough its USB out preserves lots of battery time. Rarely, some times I use bluetooth when I want to listen to radio or something else not on my SD card.
Verdict
it is near perfect as a very light player that you may attach to your headphones. It plays FLAC well, even with MQA encoding. Some of my files are as large as 80 MB because I rip MQA files with no compression at all. Despite such huge file size, M0 Pro handles them well. It is a very versatile little thing, Bluetooth in and out, USB in and out as well as its excellent dac/amp capabilities for my possible future usage scenarios as a dac/amp.
Things I wish were better
- I have migrated to all 4.4 Pentakon, thus for me I wold like it with a 4.4 out instead. It is maybe too early for some still with the legacy 3.5 out. Shanling should be able to provide both a 4.4 and a 3.5 out on this unit the way the smaller ifi Go Blu has it.
- battery life
- better responsive GUI and fast way to access the play screen and a way to force the play screen stay there not to switch to the track photo.
