@Allen, Tim:
Did we change C4110, C4111?
Did we a frequency response plot for headphone with a sweep/wobbler? (i 
guess "sox" software can generate this on FR)
Footprint of 4.7u was no problem, IIRC

@Yorik: I tested quality of a prototype (113) and it wasn't so bad, but missed 
quite some low frequency.
