I still can't believe the MA900's discontinued already. Thought it was more of a $150 headphone, which was what I paid, and then another one sold for $110 right after. I was kicking myself...only now, good luck finding one for under $200!
If Sony plans on a succeeding model, though, they'd better do something about that diluted treble and bring it back in line with the rest of the spectrum. EQ might be able to fix it, but I'd prefer not having to EQ to begin with.
Also, if they were smart, they'd make a gaming headset out of the design.
