Sometimes, a different machine will play a tape better. Eddie Ciletti
can adjust a machine for playback to match the misaligned recorder if
you run into some problematic tapes.

This is probably more a function of your interfaces than of the
media. In theory, both should be the same, and I use them
interchangeably. I don't think I've ever heard a difference.

The one place where this may help is with old DATs with the
preemphasis flag set. If the digital output just carries through the
preemphasis and the DAW doesn't honour the flag (as it might well not
as it's expecting to pass it along to the CD output) then having the
analog copy would immediately flag the offset for you and provide an
immediate "out" for dealing with the preemphasis. The analog may be
fine while the digital may be screechy.

Some early-ish (at least to me) mid-1990s TDK DATs did awful things
with head clogs--even when they were new.
