Fiio’s M11 Digital Audio Player had some pretty beefy specs, but evidently that wasn’t good enough because now we have the jam-packed Fiio M11 Pro. In this new version, they upgraded the DAC chips to two flagship AKM “Velvet Sound” chips, doubled the storage from 32GB to 64GB, put in a Fully-Balanced THX-Certified amp section, along with a bigger battery.
This thing is beautiful, super-fast, with a ridiculously transparent sound no matter the volume level. Just from a couple of hours listening, I’m in love. I haven’t scratched the surface when it comes to all the features on this thing, so I’ll have a lot more to cover in the full review. Stay tuned!

I’m an audio writer who started as a young audio salesman/consumer electronics professional back in the late 90s. That’s where I discovered the magic of 2-Channel sound. My thirst for great sound has led me on a delightful music quest that continues today.
