The Placebo Effect


One of the things that should be taken into account in the evaluation of audio equipment, tweaks, etc is the Placebo Effect.

In the medical world, Placebos (open label or concealed) appear to mostly work on subjective symptoms, such as pain. They don’t work on an objective symptom — something a doctor could see or diagnose, such as a fracture on a bone. Placebos don’t shrink tumors, they don’t change your diabetes, and they’re not going to actually lower your blood pressure for more than 15 minutes, Basically, placebos appear to work on things that pass through the brain’s perceptual systems — where they can prompt the release of opioids and other endorphins (chemicals that reduce pain) in the brain. Bottom line, placebos can result in perceived improvement even where no actual improvement exists.

The same applies to our hobby. Probably too often, we sense improvement in SQ because of the Placebo Effect. Our money spent, hardware bias's, effective marketing, or being influenced by the experience of others (regardless if true), often have us believe that we have obtained improvements that don't really exist. This is not necessarily a bad thing because a perceived improvement, whether real or imagined is still an improvement to the listener. This may explain part of why certain "improvements" can't be measured.

Mahgister, I am a realist, you are a mysticist and that is why Howard Johnson's made 28 flavors. 
Mahgister, the first thing a piano tuner pulls out is a tuning fork. The tuning fork is his reference and yes, from there the rest is by ear.

Perhaps the problem we have is that we have no reference to compare our systems to and never will. What does a band sound like in your living room? Are you even interested in that? I would think most of us would be more interested in "hearing" the venue the band was at. There are obviously systems that seem to sound more realistic and if we were listening as a group to such a system I would bet we would all agree that it was a fine sounding rig. Based of what? It seems what we usually want to "hear" coming out of a system is quite surrealistic and based on what we expect in our imaginations to "hear." Imagination. An image in our brains, a quasi electrical event which varies from one of us to the next and changes based on the emotional state of that individual. I have noticed in myself that the same system can sound different based on god knows what, my emotional state maybe? I certainly do not seem to have expectation bias. I just hooked up a brand new set of speakers and was very disappointed.  After working for hours everything just sounded worse. I had to put it away, give myself a break. After three weeks and another $500 I think I can get back to enjoying music again. But, true audiophiles are never happy with their systems because in their imagination they can always sound better.
