Soundstage and explosive dynamics?

Those would be:

1.  Linkwitz Audio Orion's or LX521's
2.  Legacy Audio Aeris (pre-owned for about $15,000)
3.  Audiokinesis Dream Maker, Zeprhin, Prisma, Jazz Module...

Or, if you don't mind a monitor, which sounds like a floor standing speaker - a real "giant killer"...

4.  WaveTouch Audio Grand Tetons / Anteros

Classic Audio T-3.3 Field Coil speakers is where it's at

To give the most sound advise  it would be good to know first Budget,
what you have amp type,wpc, preamp ,how big is your room,
room treatment  how far away are you sitting .  

@markus1299 Did you get rid of your 40.1s?

Nothing I have heard combines the best dynamic range with a disappearing act. That said, I would look at omnis like Ohm, German Physiks, and MBL for the disappearing part. Subwoofers will help the dynamics on these. Dynamic range can be very good on some omnis, because they have a lot of radiating surface relative to driver size. For the best dynamics, high efficiency models like horn speakers excel, but few that I have heard can disappear. One exception to that which I have heard is the Volti Audio speakers. These are horn hybrids that offer the advantages of horns in terms of dynamics, but without many of the downsides of horns, such as beaming, the "cupped hands" effect, or sound that seems anchored to the cabinets.
