I know you are supposed to put in your output impedence and sensitivity per IEM.

For my Blessings 3 I put: 14.8 @ 120

For my Monarch MK3 I put: 18 @ 99

I get totally different results:

When listening to the Blessings 3 “loud enough” is around 100-105 dBSPL.

When listening to the Monarch MK3, “loud enough” is around 80-85 dBSPL.

The only thing I can think of that would cause this is that one of the manufacturers spec sheets is wrong? Moondrop lists a potential variance of +/-15% on the output impedence, but even with those adjustments it doesn’t come close to what I’m hearing from the Monarch.

Any tips?
