I have all three. I would place the AFO in between the Clear and LCD2C in terms of clarity and overall balance... The Clear sound more open and dynamic to me, while the LCD2C present a “fuller” sound with more present bass. With all three headphones you have a wide range of approaches for any genre and equipment.
Good to see someone with the three.
I know it's a tricky question, but if you have to keep just one of those, which one will you choose?
