Hi Everyone, seems like I am a little late to the party. The headphone output on OPUS has been specified for professional use so you should have no issues there; specs below...
| Max output power: 300mW under 100Ω | |
| Output impedance: 33Ω | |
In terms of adding a MESA M9 inspired preamp, consider it noted down and sent to the team for consideration in a potential future update.
In terms of cab transparency, you can disable the cabinet emulation in OPUS by clicking the ON button shown in the yellow box below...

By doing this you will disable the cabinet emulation but retain use of all other processing blocks!
Let me know if this clears things up a bit!
