In this Ukrainian-language video, pidreberniy compares interchangeable op amps in the output stage of an FX-AUDIO DAC-SQ3: the LME49720, OPA2604AQ, MUSES 8920 and the Burson V5i-D.
According to the video description, the sound was recorded with an E-MU 0204, and each op amp was warmed up for 24 hours before recording, so you can hear the comparison for yourself.
The description notes that “the difference in sound is objectively felt” (our translation from Ukrainian).
