No one seems to care during a sighted A-B comparison that two components are very unlikely to play music at exactly the same average SPL.No one seems to mention that A is louder than B, or B is louder than A, during a sighted comparison when those are easy-to-measure facts.
There have been some casual experiments where listeners were asked what they heard when a change was made. I've done this many times in my own SBT's of borrowed components. The "change" was merely increasing the volume by 1 or 2dB. If this "change" was heard at all, it was rarely described as a small SPL change. It was usually described as a sound quality change.
For my own ears, starting with a modest 75 to 80dB average SPL, increasing the volume 1 or 2 or 3dB tends to make a component sound better to me, at least over the short run. That's important for me to know because a borrowed component that DOES play louder than my own component has an inherent advantage in a single-blind A-B comparison. That's why I do SPL matching.
Everyone seems to claim A and B sound different in sighted auditions, but very few people will try to prove their claim with a follow-up blind audition.
Those that do particpate in blind auditions often find themselves unable to hear differences, or are surpised by how subtle the differences they hear are.
There seems to be a gap between "I know what I hear" beliefs and reality, for some listeners.
