I don’t think it’s a good analogy. With the coffee grinders you can have objective physical measurements for the coffee particle size distribution after the grinding process. Sure, the taste improvement would hit diminishing returns as the grinder price increases, but it would still exist. You as a buyer have to decide for yourself at which point the price stops making sense based on your budget. The audiophile hardware on the other hand is being sold based on the promises that defy an objective physical reality.
