Perhaps you should be aware that Paradise is the platform, based on a chipset and software, which powers a whole line of hearing aids, and the “30” is just a service level you pay or don’t pay for various options and capabilities enabled. All the of the service levels (50, 70 , 90) have the same fitting ranges.
Most assume you mean the Audeo line when you mention Paradise, but there are others which use the paradise platform with different fitting ranges. If the Audeo line doesn’t meet your fitting need, look on the phonakpro site for their other lines and poke around.
