If pragmatism is your main concern and you can afford the expense, I think your concern is irrelevant and, ultimately, non sensical. It seems to me that as we age and our hearing gets worse, that this is precisely the time to compensate for our hearing’s diminished resolving ability by investing in equipment that is capable of MORE resolution and refinement. 50% of 100 is more than 50% of 80. No?
Anyone (everyone) care to throw a dart?
I understand my hearing at 69 isn't even close to what it was at 19. I'm sure your results may vary. However, anyone care to throw a dart at the price point where diminishing return kicks in? There must be one out there. Regards, AB
