Not at all !
The way I am interpreting this is exactly the opposite, you are presuming Ethan is wrong and going all

with no backing up of opinion, that to me is being presumptuous.
It is so no common knowledge that Simma even opened this thread because of it.
Everytime 2 or more digital equipment are hooked up, they must be locked to one master clock.
Done.
And about the recording to different DAW's, its precisely the opposite.
Its when tracking to the
same DAW that the drift causes issues.
If tracking to two different DAWS there is no problem at all as each DAW has it own AD with its own clock. So the recording is going to be phase perfect (albeit mic positioning)...
Problems would occur when recording to the same DAW, for instance aggregating devices in PT9. So , when you stack them together, you simply phase aligh them by eye by moving the waveform. Just look the the fastest transient response and adjust them, and you're set. Better still to measure the converter latency and adjust. Send and impulse and measure it. But why have that ordeal if you can just clock? This should ONLY happen if for some reason the 2 clocks cannot be sync'ed...
Just like when you insert a plug on PT LE... either you know the specific sample delay and nudge, or move the waveform until its sounds right.
Or even move the waves freely for effect, like "wall of sound" guitars, 3D phase morphing, etc.
Ethan is spot on. GS members tend to shout "fire" way too soon lately...
