I got the Int (US) version. and IMO you wont disappoint and think of getting the JP ver. Im only listening in short period, but my initial impression IMO the Bass is very special (great subbass slap, and the overall bass texture is addictive), the treble is sparklingly good and feel very natural, vocal is great, texture of instrument is great, nothing that i find wrong (not shouty, sibilance, etc) and i find this very transparent esp on good recording. IMO all is as per discribed by BGGAR in his video, i may be biased, but based on that IMO the difference between JP and Int ver will not be that much. But if there is real comparison from someone that has bought both of it will be great for other potential customer, so they can choose based on their preference.Cool and thanks! Looks like I am going for the U.S. version.
I gotta listen more longer but i think this can be my end game and reference set going forward.
