Speakers with the most detailed midrange? (non-ESL/planar)


Anyone care to give their opinion on what dynamic speaker has the most detailed/revealing midrange? Not including electrostatics or planar speakers. Approximately between the frequencies of 400Hz to 3kHz. Also, just to clarify what I mean by detail: when there is a musical passage that entails many different layers of instruments, the speakers' ability to separate all the elements so all the instruments are heard clearly and nothing is obscured. Also the ability to retrieve every last bit of information on a recording, such as random sounds in the studio, distortion in recordings and reverb tails.

As far as price goes... 2 categories... below $12,000 USD (new) and any price range. Thanks.

I can't speak for all their speakers, but the Bliss Silvers I own are very neutral. I've compared them back to back with my Spendors and the JMRs were only a tad more forward. They're certainly not anymore forward or bright than ATC or Harbeth. But I wouldn't be surprised if your description is apt to their ribbon tweeter models. I've encountered only a couple ribbons that were non-fatiguing. 
  You can't even ask a question in here without
getting 40 different models ,makers    damn 
one guy even said,  LISTEN TO B&W
 
Gonna also endorse a 3 way. ATC SCM50 would be on my shortlist, for the legendary SM75 midrange driver. Spendy, though.
Although I’m at the moment an ATC listener, PMC should not be forgotten. Their Fact serie speakers are very detailed and you can have them in all price categories. Naturally, as for ATC, also their big pro series. For ATC maybe the 20s are the best compromise for detailed (pro) sound at reasonable cost. Havn’t got it but would like to. When it comes to midrange details there are some singledrivers to investigate. Also don’t miss the studio standard Yamaha NS10 in its new creation. A tool used by most studios just to check out the midrange. Not to enjoy though!
