Ah Curt, it took me too long to type ;-) Anyway, here we go and now I will put on my asbestos dress ...
It doesn't make much difference. You can hardly notice differences between D/A filter anyway. Most noticeable are the differences between the default filter (with the most linear frequency response) and NOS, where the high frequencies are cut most.
I'm afraid you might mix this up with EQ presets (of i.e. music players) that have certain presets for different music styles like rock, jazz, classical, etc. But this has really nothing to do with different D/A filters. And .. weren't they horrible ?!
To use different D/A filters depending on whether you have planar phones .. come on .. this drifts to the esoteric corner.
I would formulate it more like this .. some planars have not so intense hights, then I would not recommend to take NOS to not lose even more high frequencies, but if you like this sound, why not. Got the point ?!
Just use the default filter for the most linear frequency response or Sharp if you like or simply whatever you prefer.
The latency of filters is irrelevant for you as Home Music consumer. Latency of different filters is only relevant in terms of usability in live monitoring situations.
There are more important aspects - like simply enjoying your fine equipment - than to make a big head about whether to use this or that D/A filter for a certain music style, I see absolutely no merit in it. If you switch between different D/A filters you will see that it is difficult enough to hear any difference for the same music.
Such discussions are typically found in HiFi forums where you can also discuss whether a €500 TOSLINK cable results in better digital sound. Some people have surely a strong opinion what D/A filter to use, but if this is so critical, then it should be evident to everybody that this or that one is better. But actually its merely audible. I am pretty sure that most people can not even hear differences in a blind test, because usually nobody has "bat ears" and if you can not hear it clearly for yourself, why you make a science out of it anyway ?! The pragmatic approach ...

. Would be amazing to get some feedback.
As has been discussed endlessly, the actual Sonic DIFFERENCES in DAC filters are Minute, and as such, barely (if even!) detectable in closely controlled, Level Matched A/B/X comparisons.
