I’ve reviewed the Questyle M12 Headphone Amplifier with DAC and it offers high-quality audio on the road. Through a laptop, tablet, or mobile phone, the M12 bypasses the mediocre audio solutions built into most mobile devices and gives you rich playback of just about every audio file format available, including MQA and even DSD formats.
I did extensive testing of the M12, wondering if it was a good solution for me as I travel. My iPhone has no headphone jack, but the M12 gives one back to me. I played local files and streamed from Tidal.
The results will be in my full review coming soon.
