Nice review! Having personally sat with both the lcd-2 and the aeon2 for a few hours, I MUCH preferred the Aeon2. It was very comfortable, had very good isolation, and great sound. It's a very nice HP for the money. I was quite astonished at the weight of the lcd-2.... like having a brick on your head! A brick with pads anyway.
A couple things I'd toss in as well:
1- The Aeon2's come with 'tuning pads', so you can make slight adjustments to the sound to fit the specific preference to what you ears like best. Personally I thoroughly enjoyed the bright & forward treble, so I kept them stock.
2- the Aeon2 has an impedance and sensitivity combination that makes them all but un-useable for a direct connection to either cell phone or computer sound card, unless you have an amp (the Ether C Flow 1.1 is also built similarly). Without an amp, at full volume - 100/100 - on my computer, the sound was about the same as other HP's with the sound at 30-40/100.
