"What blew me away was the sound of the LG V30 through my reference system. I invited my audiophile physician, Gary Forbes, to take it a listen. "With MQA, the dynamic range from the little phone was startling," he reported. "I thought the separation of instruments was better with MQA, although the horns sounded a little thin. The soundstage certainly widened with the Rossini DAC [$24,000], and there was more midrange information, and clearly more control and realistic decay of the bass. But for a phone, for Chrissakes, that's amazing sound to come out of such a little piece! How much did you say it costs?"
Believe me iv driven all my headphones with it, even Fostex mk III.
It is not an normal phone, not at all
