In some cases people have their systems tuned to deal with all the issues associated with analog so when pure clean accurate digital comes into the picture it is a problem that requires more changes.
In other cases the reverse is true.

Still yet in others the stars are aligned and everything sounds similarly excellent. But this usually happens by design, not by chance.
Just do it well no matter what and it will all work out. Otherwise probably not.
