It appears he went a different direction, and has fallen in love with a high-end Fostex.
In my opinion, I went from the very bass-light AD700 headphones to the Q701, and I don't think the bass conceals details... If anything, the Q701 is more detailed. The Q701 is not even close to having overpowering bass, and would never be a target for a basshead can... I think bass sounds very natural and balanced, it's just where I want it. People usually say Q701 bass is either tight or even not strong as they want. The separation is also really good, so you can easily concentrate on one sound amongst everything else in a game or song.
You will not have trouble hearing footsteps with a Q701 vs any other headphone. A Sennheiser HD800 or Beyer T90 may have slightly better resolution, maybe better positional imaging, but footsteps, soundstage, imaging, and detail are all extremely good and easy to hear with all three headphones. It's like saying a Bugatti Veyron is faster than a Porsche GT2, but both cars can easily pass 100 mph. Hearing footsteps is like going 100 mph.
