Yes, we are still stanning Pro 82
The choice between Pro 82 v2 and GM200 is something like this:
If you want best tonality, imaging and transparency - go with Pro 82 v2.
If you are a bass-head or enjoy bass more than the average bear - go with GM200. Bass-wise, it sounds almost identical to the 1600$ Sennheiser HD820 - HD820 has a little bit more bass, but GM200 has higher quality bass (and still plenty of quantity). Mids and treble are much better on GM200, HD820 often gets shouty and female vocals are off-timbre. Both have the same warm sound signature, but GM200 is just better.
I enjoy both Pro 82 v2 and GM200, at their prices it's not cost prohibitive to get both.
