OK, time for a question:
Suppose we have an amplifier that measures absolutely perfect, never seen better:
- 1 - 100 kHz absolutley flat within 0.1 dB
- 0.00001 distortion
- perfect square wave and pulse response
Will it sound good? Well ... it has to be the best, cleanest, absolute neutral sounding equipment we ever heard.
But will we like it?
Probably some will, but others may not, because:
- We’re not used to such a perfect, objectively neutral, sound. Our audio memory is trained over the years and has certain expectations, and this deviates.
- Chances are a bit of coloration, or THD, or both, may sound more pleasing. Which is why many prefer tubes, or vinyl, with their measurable deviant sound signature.
- It’s not for nothing that there used to be a ’Loudness’ switch and a Bass & Treble control on amplifiers. These got eliminated with high end equipment because, hey, we do have our pride! But actually, with lower SPL a bit of extra low and high would be pleasing.
Conclusion: perfect measurement results not necessarily mean it sounds pleasing. And, ’pleasing’ is very subjective. Yet, equipment designers will use measurements and will strive for good numbers first ... from there the tweaking may start.
And, if a manufacturer promises improved jitter but measurements show nothing has improved, than that’s a scam.
