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.

Monitor Audio Studio.
Standmounts. Borrowed over the weekend. May be the most clear and revealing dynamic speaker I’ve heard. Sold in hifi shops but this is more a working tool for the studio. Easy to integrate with subs while they don’t give you much below 80 Hz. New technology from top end MA range. Good on Bjork recordings (which are not easy). You hear and see every layer of sound. Extremely fast transients (folded ribbon tweeter). Try Garrett Brennan "These knees". Probably miss warmth in voices you’re used to. Yes, you will hear every recorded sibling. And every.....everything. Rather inexpensive.
Bose 901 vI 18 31/2" drivers per pair add a couple subs and supertweeters and call it a day. lol
I think the OP is asking about detail - not necessarily the most neutral/accurate (Harbeth)
What's your amp. If its a flea powered amp - then you need an easy load such as an Avantgarde Horn - but by the same token very sensitive speakers pick up and play amp noise. Something like MAgico's need power but the amps that drive them have low noise - from that you tend to have more 'blackness' from which more details emerge (that is in-simplicita)

Interesting. I have tried to like Monitor Audio. Certainly the detail is there but the lack of driver integration makes them sound so artificial. Just so obvious that you are listening to two or more drivers.
