I recently purchased 3 different sets of headphones from eBay - some Grados 60's, 80's, and 80i's. I have been the proud owner of SR325is for a year now, and love them very much. My question is this: I completely dismantled the 80i's with the intention of hand making wood cans for the drivers to go in. Can anyone recommend some good tone wood that would sound the best? I've read a lot about mahogany and ebony as good choices. Has anyone gone down this route with "sound" as their primary objective? I know the fine gentleman at headphile.com is a true artist, but I don't know if he's taken into account sound as his motivating factor. Any suggestions are welcome. This is my first post, so please, be gentle Thanks!
