I hear very large differences in PCM music between "Bit Perfect" and "Minimum Phase", which my is 2nd choice. Bit Perfect sounds very clear and crisp, while Minimum Phase has a bit of a rolled-off, softer treble profile. I prefer Bit Perfect, but find some 44/16 music sounds better with the Minimum Phase filter - glad to have both :)
The same here. Some of the older PCM recordings sounds better on Minimum Phase. This might be due to poor treble quality like tape noise on some recording. I also find that Minimum Phase is more "quiet" or a darker background in some cases. That seems to be depend on what playback software is being used. I am finding this out and checking on the repeatability on the results on various software . This is going to take some time. I have to rebuilt my music library since some trial software like Music Bee made a mess. I have to revert all the changes the software made and to the system. I always make a total system image before checking out new software.
I do find that the phase switch setting is subtle from what I am hearing, but still in the early stages of evaluating.
