separate rectifiers for input and output stages?

Is there an advantage to using a separate tube rectifier for the input stage of a SE amp (shared transformer but separate rectifiers and PS), compared to the usual practice of 1 rectifier and the input stage PS connection "downstream" of the output stage connection? How about compared to a shared transformer but separate rectifiers and PS for each channel? I tried a search but found little on the subject.Perhaps my search terms were too vague. The power transformer is a Hammond 278CX, and I have a separate 18A filament transformer, so having enough current for extra filaments is not an issue.
