Some say its because the drivers are run in yet. I don't really know. Fortunately, the strange bass that the CDM1SE is famous for is minimised in the N805. Joseph Audio RM22 and 25. The sound is arresting, there is also subtlety and delicacy in the sound.
Transients are of course superb.
This is the sound of metal drivers. It all depends on whether you like it like this. The other metal driver we all know about is the lovely but rather coloured Monitor Audio PMC series. The 'big speaker' 'big sound' stereotype. Without the dryness, and the compromise is weaker transient performance.
