suggest an integrated tube amp for me

How about a c-j CAV-50 I think the model number might be? I think that would work well, or a Rogue Tempest, or the Audio Research integrated, the model number of which escapes me. Happy listening!

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.

For those speakers, I would suggest a hybrid amp like the Unison Unico or the Pathos Classic One. I think they will give you much better dynamics than a full-tube amp would but you will still get tube sweetness in the mix. And tube rolling still remains a possibility.
