Mar 22, 2022 · OPA1612 (soic on dil adapter board), bi-polar from input to output, again a very good opamp, which to me "sounds more balanced" top to bottom than the LME, it is just as dynamic, but just a little less obvious in the bass leading edge because the mid-range seems a little more fleshed out rich and full bodied, highs are just as good as the LME. For gain: OPA209 but only against NE5534 and V6V singles. When we developed the OPA1656, this was also a major design target for us, and the designer and myself spent quite awhile in the lab with previous CMOS audio op amps (specifically OPA1652 and OPA1688) hunting for sources of input capacitance variation. Jun 7, 2016 · I previously replaced the B4s stock op amp (TI NE5532) wih an OPA2107 and notice a significant improvement. strangely its probably the most boring sounding one when paired with 400i but the best sounding with hd600 Apr 17, 2022 · I think audio grade OPamps, in the right application, are very good.
