(F) The optional Filters give different trade-offs between impulse response and aliasing.
For most conversions, only
0.1dB to match the other filters.
The best filter setting is a personal choice and may be related to the type of music.
The table below shows how many filter choices are available for each input / output combination.

For conversions with 2 filters (currently all of these have a 44.1k input rate):
Filter 1
is a classic sharp filter.
Filter 2
is a very steep, long asymmetrical (sometimes called apodizing) filter which starts rolling off at
20kHz. This filter has no energy left in the output to exercise the DAC's filter, so there is no pre-ringing
from the source and the DAC. This will improve the response of the DAC's reconstruction filter by
removing some high frequency components that typically cause images in half-band filter DACs.
For conversions with 4 filters:
Filter 1
has the sharpest cut-off, and so has the poorest impulse response (transient performance) but
the best alias rejection (removal of out-of-band frequencies).
Filters 2, 3 4
and have progressively gentler cut-off, with less alias rejection.
