Is there a modern equivalent of Allison Ones?

So there is no confusion, the left speaker could go in a corner or up to 3 feet from the corner and the right against the wall but not in a corner. Don't the Revolution and/or Evidence need 100 WPC of SS power? I have a tube amp, 60 WPC (Jadis DA 88 Signature) that may not drive the passive Revolution, according to the reviews. Size is not an issue, Duke, as they can be as high as they need be and provided they are not hugely wide, not an issue. I will look into the Audio Note. Thanks for the helpful suggestions, all.

Springbok10, it might be best to pick the speaker that works and then match it to an appropriate amp.

Are you willing to consider on-wall or in-wall speakers and DSP room correction technology?

Some of the Linn speakers - the older Keilidh and Kaber and the current Ninka - are designed to be placed against the wall. Perhaps some of the other Linn speakers as well. Likewise, the Naim speakers. The designers at Zu claim that theirs can be placed against the wall aas well, but I do not think that they are deliberately designed as such.

i currently use an mc275 to drive the gradients. they can be arranged in a variety of positions. they love power, but years ago i ran them using a 40w cyrus.

I'm not sure about the aims of the designers vis a vis front wall proximity, but the Zus do work well that way. I started with Druids and moved up to Definitions and both worked very well against the wall. My Defs right now are toed in slightly with the nearest rear corner 11.5 inches from the wall behind it. These are sealed cabinets with 4 rear firing subs per speaker. Regardless of how well these may be theorized to work, the net result is literally world class. The Druids have a sort of transmission line which fires downward and is calibrated by adjusting the height above the floor via turning of its spiked feet. Optimized set-up requires comprehension of the design goal and experimentation. Where successfully implemented the Druid will exceed the performance capabilities of almost anything else within its price range. Both of these speakers are badly misunderstood by many forum contributors and mostly overlooked by the mainstream press. They are very worthy of your investigation.
While I am not familiar with Gradient myself, I would take a look at those as well based on the respect I hold for some of the contributors who recommended them. I believe Gradient is a company that made it's reputation designing the only subwoofer that ever successfully integrated with QUAD electrostatics.
