Warm romantic & detailed

You may like this pair of Acoustic Zen Crescendo speakers, used at an outstanding price. I think it may match exactly what you're looking for.

@djones, the BBC curve drops 2.5 to 3 dB from 2,500 to 5000 Hz. 

@jeffinh76, this is a job for Magnepan 3.7i's which we were just discussing in another thread. Add subwoofers down the line and you will have a very close to SOTA system. The 3.7i's will give you a sense of space and the third dimension that you can not get from typical box speakers. They are not the loudest speaker so if you like Nine Inch Nails at concert level they are not the speaker for you. They will plenty loud. Loud enough for most people. The subwoofers add dramatically to the sense of volume. 

Talking about NIN, The Downward Spiral is playing at this moment. 

OP what happens with the tone control. Set flat it does that?

Are you using a silver clad wire? for speaker ICs?, Again are you using silver clad wire, in you IC between source and Pre, and pre amp to amp?.. All of those can add a lot of "BOIL to the mix"  Right over your head, with 8 foot lids... Treat the heck out of it.. Rake the speakers 3-10 degrees. BACK, get the highs further over your head... Make a sticky foam filter for the front of the tweeter, sides, top. ALL low dollar checks, even the IC, use some less expensive copper... look out for silver right now... Gold terminals.

Jeffinnh, thanks for posting information about your preferences and your amplification.

Can you tell us a little about your room, and what your placement constraints are?
Imo SoundLab fullrange electrostats... "used" in your price range... meet your "warm, romantic, yet detailed" criteria, and are totally non-fatiguing, assuming they are feasible for your room.
