Wen your ears can overcome a bout of upgraditis....that's a very good place to be.
My HD800 monitors me from afar....just in case.
I just picked up a pair of HD600, I have had the HD650's before but found them to have a touch too much bass. These HD600 are just amazing. <3
They are both great. But I also find it harder to go back to the 650 after 600.
I find the 650 bass very effective for rock. But the 600 has more energy for female vocals, which I listen a lot.
