I run my Opus 21 directly into my amp which ims sounds better than the SF Line 3 it replaced. To further determine if the Opus 21's volume control could be improved on my neighbor let me borrow his Placette passive. Using the same ics (Pure Note ERs) I couldn't tell any difference with the Opus 21's volume set to 99 and using the Placette to control the volume. What I don't know is if the volume is fully bypassed in the Opus 21 when the volume is set to 99.
