Came home late last night and the La Figaro was there. Stayed up an extra hour blissing out to music with both my Aeons and HD-6XX's. I could have stayed up longer but made myself go to bed (it was after 3:30AM).
I have some tubes to play around with but have only listened to stock so far. I like to totally get used to the stock sound before changing the tubes so I can really hear the difference.
This amp drives the Aeons wonderfully, so much power, I could barely turn up the volume (same for the Sennheisers). Lots of detail, intimate sound stage, and the best bass I've heard so far aside from using the bass boost EQ on my iDSD BL. I have the amp paired with the Mimby.
This amp confirms that the Aeons are not boring but you need to drive them properly. When I first posted this thread that was my concern. I also have a better understanding of what "the Sennheisers scale up really well" means. I would say the same for the Aeons.
