How to find the right audiologist / hearing aid

Are these all BTE as RIC form factor came later with digital?

From a sound perspective what is different between these fully analog and the later ones that are analog but with some digital programming? Perhaps it is easier to maintain the fully analog ones as you use a small screwdriver for adjustments and not ancient software tools?

I’m tempted to find an analog pair to try but with cookie bite I might be wasting my time. Were there analogs with different adjustments at different frequencies? Even a small amount of flexibility might make it tolerable for cookie bite. For example, could one not make an analog that is effectively three in one, lows, mids, highs, each with independent adjustments?

Analogue, yes! Normally I listen to the world through well-fitted Phonaks, six year vintage. But from curiosity I tried a pair of Chinese non-digital in-ears. Not quite bright enough for speech, but decidedly sweeter on music. Digital messes up complex textures like a choir or deck of violins. Price new: six pounds including postage.
