Yeah, I’d say it was an issue with your hearing ‘professional’ for sure. Like I said before I have listened to dozens of Starkey aids including the S series, IQ, and Wi and none of them have an issue with circuit noise. In fact I listened to a lecture by one of their scientists who showed his evidence that in fact their current circuit is by far the quietest on the market today, and thus best suited to someone with a very mild loss like yourself.
It is this very reason that they are legally allowed to claim that their hearing aids ‘reduce listening effort’ by ensuring extraneous and artificial noise is minimized (feedback, mic noise, circuit noise, computer noise, interference, entrainment, etc).
Any of their latest stuff should sound great to you provided it is the lowest power and open fit, and not fitted by a moron.
