I go way back with amps - 1974
SAE 31B, Dynaco 410, Threshold Stasis 3, Krell KSA-100, ARC D-52, Jadis Classic 100, Pass Aleph 5, Classe CA-400, Pass X-150.
The Wotan is very similar to the Pass X-150 IMO. Big but fast and trim bass, coherent, clean almost soft treble.
I run the Kara/Wotan/Yggy Singular driving the BMR Philharmonic Monitor v2 which goes down to about 2.8 ohms briefly in the bass - no issues.
I dislike underdamped bass, the Wotan has no issues with that.
Have not heard a Coda so I cannot address that comparison. The Schiit Tyr have an even more pure sound than the Wotan if that's the goal.
