Consumer fraud regarding vastly overpriced and sometimes just inflated copies of audio equipment and accessories - - - I have been preaching about this for the past fifty years and nobody listens. Maybe now?
It would be fun to take apart a $50,000 power amp and actually price it out, part by part. Remember that 1% precision metal film resistors cost five cents each.
There was a cartoon in Stereo Review many years ago that I wish somebody had and could post again. It was a photo of a couple in an audio salon looking at a very expensive giant refrigerator plus sized speaker system. On the back panel there was a warning, "DO NOT OPEN BECAUSE OF SHOCK". They opened the back panel anyway and found that inside the speaker there was only a small car radio speaker driver. Next to it was another sign reading, "See, we told you that you would be shocked".
