HIFIMAN HEADPHONES COMPARISON: closed-back dynamic HE-R9 vs open-back planar-magnetic Deva Pro 

Yes. Keep em comin‘…:-)

I have the Deva Pro's paired with Ifi Zen Can. I have to switch Xbass and EQ the bass with additional 10db, so I get good juicy bass lines. It sound really good this way. Is there big difference between the Deva Pro's and the R9's in the soundstage department? I heard the R9's have really wide soundstage for a close back headphones.
