The 5200 should be at level of a th900 or TH-X00 driver Because instead of the faster carbon mix diaphragm of the 7200,
it is using a paper type (biocelulouse typr) diaphragm, similar to those Fostex drivers.
This is interesting. Just sifting through this thread, reading about the AH-D5200 as they are currently at a good price on Amazon and i'm thinking of buying one, now I think I will buy the AH-D7200 instead! "faster carbon mix diaphragm of the AH-D7200"...
from that comment, it sounds to me that the drivers of the AH-D7200 may be a little bit superior. Interesting stuff.
