Tus-Chan, DefQon and Ali-Pacha, thank you for answering my question.
Haven't heard the whole AKG K70x series, but I have heard the K701 a few years back and distinctly remembered hating the sound.
It is open, but the sound is simply too blend like a mesh of thing.
I found the Phonitor to be very good with the HD800, but at that price you would expect it to be.
Back to Stax, anyone heard the Stax Pro Classic. I can hardly find any information regarding this one.
