Just received mine, ordered June 28, about a month before expected! They sound great right out of the box, should be awesome after some run-in time. First thing I did was plug them into my iBasso DX90 and listened to several tracks from Miles Davis "Kind Of Blue" hi-rez download. Great soundstage & instrument clarity with these, they are terrific with acoustic instruments! Next up will be Woo Audio WA7 and Grace M9xx. Thank you Massdrop!
