But since Apogee Duet is quite expensive, relative to Apogee One (and of course to ODAC too), I am wondering if One serves the same function for audio playback (I read people saying that One only has mono recording whereas Duet has stereo...).<br /><Rickhttps://www.blogger.com/profile/15112871610000278741noreply@blogger.comtag:blogger.com,1999:blog-6890046273025265768.post-33018982569961314652012-01-31T19:56:53.023-08:002012-01-31T19:56:53.023-08:00Just repeated the test with 1 Ohm open and I got a...Just repeated the test with 1 Ohm open and I got almost exactly 0.25 V into 10 Ohms.
