In looking to buy one this month but not sure when they may change the auralic mini. Which unit has the best sound quality in stock format blue sound or auralic mini, which has the best potential sound quality? I want to stream tidal through a streamer. My budget new or used is under $600. I have primaluna prologue 2 and omega 3xrs speakers. I have a Concero Jd and bel canto Dac 2. I love soundstage , imaging and resolution. Female vocals acoustic guitar and piano are the instruments I like. I don't listen to much complicated music.
