Fiio M3 Pro is actually 37EURO cheaper on ali. 66 vs 102 euro. It's a big difference!
Q1 seems to offer a more mature and refined UX? I'm not sure, it looks so-so on both, but slightly less clumsy on the Q1
Q1 support opus, which is a big plus for me. It also has a bunch of wireless features which I don't care for but might be useful in the future.
Q1 has a warmer tuning as I've read on a review. M3pro kind of bright sounding (What do you think?)
Q1 has a way more attractive design. Better button placements.
M3 Pro is lighter. Maybe the form factor is more practical in the end?
Shanling has a better support of their devices than FiiO it seems. They also seems to listen more to their users. But maybe Fiio improved on that?
Overall i find the Q1 to be better although nothing really killing it and M3Pro is nearly half the price.
I want to use the DAP as a transport with an external DAC. Which one do you think better support this usage? Maybe they are about the same.
Don't have the M3 Pro, but I would say the Q1 to me is a tinge on the brighter side actually. The subbass/midbass seems a tinge less defined on the Q1. I tried using my Q1 with a tempotec sonata HD Pro a few days ago, works flawlessly. But I did read reports that it clicks when used with an external amp? Have to check with the others on this.
I was contemplating between Q1 and M3 Pro, but what made me buy Q1 is cause it has 2 way bluetooth, whereas the M3 Pro doesn't, so it might be useful for those wanting a wireless connection. Also, Shanling seems to be very good at supporting their gear even months after release. They just recently released a firmware update that allows WIFI connection for the Q1, so I do appreciate this aspect of Shanling. I like the longer battery life of the Q1 too, with an attractive UI.
During sales the Q1 can be low $90s USD, which was the price I paid during the last Aliexpress sale. M3 Pro is cheaper for sure, and if u don't need bluetooth maybe that is a cheaper option.
