We're not missing anything. When I listen to a $99 DAC with a SINAD of 123, then switch to a $100 DAC with a SINAD of 122, I rest easy at night knowing that the $99 DAC is superior in every possible way in the universe. Then I rush back online to see if that dreamy Amir has given one of my comments an upvote.
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?
