MLE, I still think you're making a mistake, and that once again you've materialized some reasons to sell what is obviously one of your favorite headphones. The reasons this time being that the LCD2 has a little better bass, and that the two have some similarities - so you MUST sell the anniversaries, even though you love them. Your always going to find some similarities in whichever headphones you've got, so you're always going to find some reasons you can use to convince yourself to sell them all off, regardless of which headphone it is and how much you love them.
I still don't understand the logic that says you can't keep two headphones around - even when you've said multiple times that the anniversaries do many things better and you prefer them for many reasons. I seems so obviously flawed when I say it out loud.
It wouldn't be as big of a deal, IF the anniversaries weren't getting harder and harder to acquire. But they are, and they will be.
For whatever the next headphone you get, I can see keeping it for a while and then coming up with a couple reasons to sell it, or the LCD2s. I can also see you later deciding that you miss the Anniversaries and want them again, but you may be unable to find them, and will be kicking yourself for not holding on to them *cough, D7000*
I would advise you to read my previous post again. I see you went ahead and listed them. I guess my words have fallen on deaf ears.
I'm really not trying to sound mean or anything, I'm just trying to have you take a step back and look at the situation and see what appears to me (and several other people) as obviously flawed logic for selling one of your favorite headphones.
