I don't think the Rogue Cronus will be able to drive the Aerius effectively. Martin Logan's like power to sound their best. Tubes are a great match with electrostats. I am driving a pair of Martin Logan SL3s with an Audio Research Ref 110. I find this a very nice match. But I have found that less powerful amps make my SL3s sound closed in.
How big is your room? The SL3s work really well in my 13x24x9 room. The Aerius are a bit smaller than my SL3s. They may not sound their best in a very large room.
