Using it for more than 2 years now. Currently it's my fav for portable use, tried various DAPs upto $300 but nothing beats this in terms of SQ. Also compared to Schiit Modi2u in DAC mode only Modi has better highs but CEntrance is ahead in bass and soundstage. But mids is where is shines, Modi sounds cold in comparison. Wish @CEntrance makes a DAC only device in budget range it will be a success.
