Perhaps Duke from Audiokinesis will weigh in here, but I don't think that a $1500 tube integrated is going to adequately drive the Aerius'. Tubes are a fine match for true electrostats which keep their impedance high, but Martin Logan's are hybrids, and the Aerius drops its impedance below 4 ohms.
For that price range, I think you'd be better served with a high-powered solid state integrated such as the Plinius 8200 or an inexpensive preamp with an Innersound ESL amp.
Just thought I'd present another perspective.
