Hi , I would like to know what you'd recommend me. I'm thinking in buying a dac/amp and i don't know what could be better option , buying the x6 dac or buying a mp3 (with a good dac and amp ) that can be used like a computer dac. I'm interested in the mp3 because i travel a lot but I don't know if there is a good mp3 with the characteristics i search (Good dac , that it can be uses like pc dac , under 100$ max 150$). And I don't know how can be compared the quality of a portable mp3 with a desktop dac. Thanks! Pd: Actually i have an s7 edge and a htc one m7 so i would like to get an upgrade in sound quality.
