The cheaper S Series 5, can also go to 71dB of gain:

Both of these models are newer and superior to the Destiny range, the IQ having the extra advantage of voice recognition which can greatly enhance background noise suppression.
Now although they only advertise 71dB of gain, remember that more of this is usable than many other brands because of superior feedback cancellation.
I can tell you on good authority that they can get more gain out of these aids if they have to, but they don’t currently advertise anything higher than 71dB of gain in a CIC. But I know for a fact they have gone several decibels higher than this when they need to. Frankly though, they don’t need to very often and don’t want some horse power happy hearing professional ordering more powerful models as a matter of routine.
I can assure you though, this is a monster power circuit, and if set on the low or non-compression fitting algorithms will satisfy some very power hungry patients.
Finally, I can assure you that both of these aids blow a Destiny out of the water, they are vastly superior in every way. If a hearing professional told you that the Destiny was the only power aid Starkey makes, this is only partly true and certainly not in the CIC range at all. They may have been thinking of a BTE power aid they make with Destiny technology that can do 80dB of gain.
