I am not sure how many people know this, but since tomorrow is the last day, for people who want to buy HD558, this is a great chance to just spend few more and get HD598. http://www.frys.com/product/7821729
If this isn't allowed please delete the thread. just I spent so much time to compare price and trying to find the lowest one finally found it.
I hope it can help someone's wallet.
Also for my 1 day old HD598, can anyone explain how to "burn in" it? Just turn the volume to max for 72 hours for whatever song?
