Not so fast. Fidelity and sound quality, while related, are absolutely not the same thing. Fidelity implies reproducing sound as closely as possible to the original. That's fine for SS devices, but very cumbersome to define and measure for loudspeakers (unless your living room is a replica of the mastering studio). Sound quality, OTOH, is a subjective, human-reported characteristic or judgement about a sensory input that is neurally processed.For the most part ASR defines sound quality as fidelity, and according to scientifically derived standards (Harman) when there is not a linear relationship between input and output. This is useful because fidelity can be directly quantified, but as you note, you might want something else / more.
Harman recognized this dilemma and in their research, the chose not to chase loudspeaker "fidelity" (whatever that means), but rather, listener preferences as their research target. They wrote about why they decided to study listener preferences to inform loudspeaker design. I would encourage anyone interested to read about it.
You'd be surprised.The data can take you pretty far but I don't think most members here believe the data is the destination.
