[Elecraft] RX Test (long)

[David Christ]

As I recall it was RCA at the dawn of HI-FI who did a test using a 
live orchestra and a physical passband filter  to garner listener 
response.  The audience did not know whether the filter was in or not 
The results were that people found the orchestra without the filter 
sounded unnatural.  Their conclusion was that people had become so 
used to listening to the limited frequency response of the radios of 
the day that the real thing did not sound right.

Caveat:  That is my recollection.  If I remembered wrong it still 
makes a good story.
