I wonder how high the average speech spectrum LTASS (the green shaded area) can be placed. The MPO may exceed 120 db so if the top line of the shaded area can be placed near 118 dB level then the high end of MAOF will be over 1700 Hz for the left ear in my case.
The Enhanced Audibility Extender and Spectral iQ can go lower than Sound Recover 2. The problem is the lack of a decent Widex HA in the ultra power segment, Widex Super is close to ten years old. Starkey offers Muse iQ Power Plus that is an UP aid but AFIK there are some limitations by the software.
