Even questionable audiophiles say the Behringer ruins the sound, and not just because it's digital or switching back and forth. Because the unit ruins the sound more than other components or A/D, D/A switchers.
Most audiophiles use the Behringer only on the sub, whose frequency range is where room EQ makes by far the most sense anyway.
(I took the thread to mean "is EQ a truly audiophile practice," not "is the Rives device transparent enough for audiophiles.")
