I agree short of the Soundlabs, none of the speakers really compete with the Monolith III's except the 20.1's.
And that is more of a sideways move than an upgrade.
If you want a smaller speaker that is electrostatic etc... look at the Innersound speakers. Smaller footprint and very good when used with the active crossover.
Since Canadian Hifi is no longer an ATC dealer you can score some nice ATC's from them, which will be competitive with any of the speakers mentioned, a little different but just as well integrated and more dynamic.
