Hello:
In a previous post, I shared that after the firmware update and completing the new feedback test, the MPOs and feedback curve values showed an increase. I included both charts for comparison in that post. The link is provided below for your convenience.
I noticed sound changes, so I decided to take a hearing test to check for differences before and after the feedback test. There were changes above 4K. I repeated the test 5 times.
I’m not going to speculate on the cause, but the mix of higher MPOs, increased feedback curve values, and potentially lower gains feels unusual to me. This only occurs after running the new feedback test.
I’m keeping my old program as it provides better results for me.
This is just a test, and I’m sharing the data. It might not be relevant to you and may not hold significant real-life importance.
