MSR7 does sound a bit hyped and artificial due to its very forward presentation, the boost in the upper mids and a lack of soundstage, especially compared to decent open headphones. However, it's still a highly resolving, clear and tight sounding headphone. The bass, in particular, is extremely tight and well defined on the MSR7 - some of the best bass out there - and the highs are just pristine and, again, some of the best I've ever heard. My HD600 sounds more natural, but MSR7 has the edge in clarity, control and speed. I think MSR7 represents the most technically capable sound you can get at under $500 or perhaps even under $1k. I wouldn't consider any of the sub $1k headphones I tried to be more technically capable than MSR7. For a balanced and natural sound, however, many better options exist. The aformentioned HD600 is more natural sounding than MSR7 and I am sure that so is the R70x. Open headphones, in general, sound more natural and, often, more neutral, even and dynamic. I would actually rate HD600 above MSR7 in overall sound quality because HD600 sounds significantly, more open, more dynamic, more neutral and even, despite lacking a bit in certain technical aspects vs. MSR7. There are headphones, including HD600, that are as resolving and refined, or even more so, than MSR7, but don't sound as clear and controlled. I am considering the overall performance here. For a closed headphone, MSR7 is definitely one of the best. There are still more natural sounding closed headphones, like NAD HP50 or Focal Classic, but I think MSR7 has those and most other closed backs beat in technicalities.
In sum, I would say that MSR7 has the best clarity, focus and control I've heard in headphones - there's absolutely no sign of any muddiness or sloppiness to be found with this headphone. Even my HD800 seems a bit soft compared to MSR7 and not quite as razor sharp. MSR7 is also one of the fastest headphones - its transients are amazing and can even beat out planars IMO. In other aspects of sound, MSR7 is not quite so great, but still at least very good, especially in its price range. IMO, most open backs in MSR7s price range sound nicer, more natural overall. However, at what it does best, MSR7 is nearly unbeatable IMO. I guess one can say that MSR7 is a pretty specialized headphone, although that's not really true because it does everything acceptably. Although, it's certainly not an all-arounder either.
The Detail retrieval you are suggesting comes only because the MSR7s have been EQ'd to be bright, which of course allows for the slightly fake - extended- "articulation".
But if you need that then get the R70xs and just increase the 5khz-10kHz on your fav player's EQ and you can have it all day and all night for as long as you like.
But if you want balance and no fake'd high end that gives you false "detail retrieval" as the expense of audiophile natural sound, then get the R70x's.
I agree about fake detail on the MSR7. I think it does push some details too forward. However, MSR7 is definitely not bright in the 5-10 kHz area. It's quite neutral in the treble. MSR7's coloration is in the upper midrange around 800Hz-2kHz. Other than that, I think the headphone is pretty neutral.
