What size is your room?...if you are looking for a speaker that can recreate the illusion of 100 people on a stage, then you need a room that can support that illusion. If you have a 12' wide typical listening room, with the speakers 7' apart, you have about a 14' wide stage to create your illusion, assuming that your speakers throw an image outside of the physical boundary of the speaker.
If you are looking therefore to recreate larger scale orchestral music with some degree of 'believability', you will need to be setup with more space between your speakers, and ideally more space around them (sides and rear) to help build the image.
If you have the space, then something like the Magnepan 20 series might be what you are looking for. They can be picked up for $6k or so used, but I can't say for sure that they'll work with your Mono's, since they are pretty power hungry.
What you are striving for is not unreasonable, but your room will be the biggest constraint, in my opinion.
