After finally comparing the Rev 1 and Rev 2 side by side at least some things became clear to me:
- They are more similar than different. If you are asked to blind test both of them at the same time, chances are you won't be able to differentiate them on certain musical tracks.
- The Rev 1 has a better midrange, this is not even a question for me and it was the first difference that I notice. The midrange in Rev 1 is more neutral ie. it's more natural and it conveys a better sense of texture and decay than the Rev 2. Vocals especially sounds more real and nuanced in Rev 1. The midrange in Rev 2 while still good now resembles the Hifiman HE6 more. It's slightly thin and a bit brittle/edgy in the upper midrange area.
- While the Rev 2 is inferior in the midrange, it makes it up with an improved soundstage. Imaging is more or less the same to me but you definitely get a better sense of air in the soundstage. This significantly helps to clear the congestion in the sound as separate instruments gain their own spaces and do not blur into each other.
- As for the treble, I would still classify both headphones in the dark side of things. The Rev 2 sounds slightly clearer than the Rev 1 which I attribute to the thinner midrange and airier soundstage so it's easier to pick out treble details.
So honestly, I'm still not sure on what to feel about the Revision 2. You basically trade off some things to get another. Can't I have both?
