I recently got the Vivo X50 Pro which comes with the AK4377A DAC. If I'm not mistaken, that DAC is similar to the Fiio M5? I've been eyeing on a used LG G8 for quite a while now but my phone carrier just got a good deal with my Plan and got this phone at a very good price.
I'm honestly loving the sound of this despite being a headphone jack-less phone. I've always thought the usb dongle would lessen the quality of a music track but surprisingly to me, it didn't.
It's like a night and day sound difference coming from my samsung galaxy S6 and my computer desktop. I've been listening to some 24bit/96khz music from my desktop for years and it sounded much more cleaner on my Vivo X50 Pro.
If this DAC already sounds fantastic for me personally, I can't imagine how great the mid-ranger daps will sound like.
All I need now is to upgrade my IEM. Been using my TFZ Exclusive 1 for the past 3 years now.
For those who are wondering about the phone I'm using -
