You need both objective to get a base to replicate or advance from and subjective to tell if it's enjoyable since that can not be measured. Nearly all audio products built by subjectivists have parts or materials that were carefully measured and meet specifications based on advanced objective measurements. All objective products meant for humanity’s replication of art must work, feel, sound, or look good to humans and that’s all subjective.
What are we objectivists missing?
I have been following (with much amusement) various threads about cables and tweaks where some claim "game changing improvements" and other claim "no difference". My take is that if you can hear a difference, there must be some difference. If a device or cable or whatever measures exactly the same it should sound exactly the same. So what are your opinions on what those differences might be and what are we NOT measuring that would define those differences?
