I suspect that the x-rays built into the quality inspection loop actually helps improve speed and quality. They're getting real-time feedback about voids and geometry, then they can tweak build speed and EB power to optimize quality. So while Jack Beuth's assertions about the trade-off between speed and resolution may still be true, the newer Arcam machines might be pushing the envelope; they're getting better quality at higher build speeds and the trade-off between speed and quality still exists but at even higher build speeds and quality. Previously they were, in comparison, running blind. X-rays have been used since WWII to evaluate metal quality so I'm sure that technology has advanced to a high degree.

We'll have to find patents or research to find the answer with any certainty.
