This thread got crapped on by you posting your ridiculous offer to Dan Lavry. It was good of him to post here and then you had to ask him for a DA11 in trade for some used headphones. Plus, do you really think he knows what an APS cable is or cares if you have extra chrome housings? If you want a DA11, sell your cans and buy one. Don't put a vendor in a bad position by publicly asking him for something.
Also, nobody cares if you posted positive comments about the DA10 after listening to somebody's unit however long ago. The criticisms and comments about your offer would be just as valid regardless of what you said before, and you can either roll with it or act like a jerk. You chose the latter, mixed in with much whining.
If you don't like the results of posting here, then don't bother. I cannot understand why you continue to try so hard.
