AMTs are in general, the opposite of what I would recommend for the OP.
You can buy Mundorf bipolar AMT's at Madisound. Excellent performners, but you'll need to make a little stand. Not much more than a block of wood with a slot cut across it for the tweeter's lower lip.
HOWEVER, they simply do not sound like what the OP is asking for.
They are glass smooth. Supremely natural.
Golden Ear Triton one's achieve this by a severe boost around 10 kHz. If that's the sound you want, you need to sculpt the HF response.
