Phase Shift is the enemy Marcel, I would never send drum mikes through two AD converters......never.

Strictly speaking, you're doing just that if you use more than two channels for drums. The standard pro audio converter chips used in most interfaces have two channels. A 16 channel interface has 8 of them. OK, they're running off the same clock, but that's also the case when running several interfaces from a common master clock.
Running a stereo pair through two different
types of converter would most likely cause phase problems due to the different amounts of conversion latency (not an issue where all converters are the same type).
Similarly, splitting a stereo pair across an interface running on internal clock and another one slaved to that can also give phase problems because the slave interface is likely to receive its clock signal slightly later than the ADCs in the master interface.
