I'll have a beer for ya.
have you ever seen the bathroom.......
Make it four and you've got a deal.
haha!! I solved this long ago with a simple house rule. Nobody in the master bath but me and my wife.
And you probably have an excellent shotgun collection for keeping the suitors in check :P
I should have been more specific. I meant on an old denon headphone. I don't think it was head-fi some other headphone site. A gentleman bought some wood cups from Lawton, back then only $89, and drilled a hole only a quarter inch in diameter in the middle of the cups and stuck them on his d5k. If I remember correctly it improved the soundstage but sucked out all the bass. Going back like 2-3 years though so fuzzy memories. Some really small bass ports ala thunderpants might work.
I just bing'd it. Looks like MCA made some denon open back cups with some huge holes in them. Maybe martin would do the same for your 900 cups. Looks like he took it to another level than just drilling a small hole in the center.
