Bongo,
Please don't take this the wrong way, but what you suggested is pretty much the opposite of what the Rana_Kirti is looking for.
Don't get me wrong. ATC makes fine transducers. But their well documented tendency towards being rather unforgiving of poor recordings is at odds with Rana's goals. And the B&W 685's you mentioned are simply outgunned in this company. A more suitable B&W entry would be the CM5 - which too falls short of Rana's criteria as it is a bit tilted up along the treble.
As for the bass on the P3ESR's.. I have zero problem's with how they portray hip hop, electronica, rock, metal, or any other kind of music when set up in the near field. What they lack of laser-like speed they more than make up for in terms of tone and, (within their physical limitations), density..
