Positive Feedback | Questyle M12 Mobile Phone Headphone Amp & DAC - Great Hifi On the Go

"If you are in a place far removed from a quality two channel setup and need your HiFi fix, the Questyle Audio Engineering M-12 Mobile HiFi Headphone Amplifier with DAC delivers the goods. As their site says, "(the) M12 allows all mobile phone users to break through limitations of technology, cost, and size of the audio circuit integrated into mobile phones, and...enjoy lossless music from streaming anytime in any place." And it does so with realism, verve and panache!"
