I ran across this discussion of Pejudice & Bias on YouTube

At 74, I just "got" synergy.  Recently upgraded to MSB dac/pre and S202 amp..  Wow, huge audible improvement that these old ears can hear.  Interestingly, most reviews of equipment are done with a cafeteria of equipment,

Bias is a human trait (weakness) we all have. Many times it leads to unfair judgements and poor decisions. Smart business has learned long ago how to profit from it. ( "Sell the sizzle, not the steak" )

Audio is especially suseptible since sound is invisable. This is fertile ground for the imagination to take over and hear things that aren't really there. The problem arises when someone accuses you of being unable to hear it also.

The guilt trip... "The Emperor's new clothes" ... Certainly you're not so stupid as to put cheap cables on your new expensive stereo! This would be a foolish move if you want to get the "best" sound from your system!

A box of 'special' moon rocks in the corners of the room will transform your system to new levels! Certainly you're smart enough to hear that, don't you???

The list goes on.
