Received mine today as well! Right off the bat (as I can recall with v1 and 2) the treble was pretty sparkly but definitely anticipate (and hope) for it to calm down after putting some hours on it. Jazz (ahmad jamal the awakening, art blakey come rain or come shine) sound excellent as they do with all of the other versions - it widens the soundstage (at least to my ears) of my hd650s. Instrument separation is excellent while still staying very musical and fun - not overly analytical. One thing it stays true to is the airiness of the instruments and vocals which I love. I can't directly compare the bass extension but v3 delivers excellent extension - not quite the "slam" that my arrow 3G provides at bass II but distinct/deep and well balanced across the other frequencies. I've owned the continental many a times, but always miss it when it's gone. This one's a keeper for sure!
iPhone (EQ off with jazz/classical, "rock" w/r&b & hip hop to inc bass though it drastically narrows the soundstage and decreases the airiness) -> clas -db single ended -> continental -> hd650
