In the end, after listening to Sennheiser Momentums, Sony R1, Yahama 220s and pro 500s, AKG 550, Audio-Technica A900X, PSB M4U 1 and 2, and some random other cans... I bought second hand A900s with new ear pads. Happy with that decision too, 1/4 to 1/3 the price of the new ones, and better sound than any of them - to my ears, from portable sources. If AT fix the A900X head band then it will be a killer headphone, not portable at all, but very capable.
