[Elecraft] Compare: K3 to Collins S-line receiver

[David Christ]

I can’t find the article/reference right now, but I recall reading about an experiment that NBC/RCA/Bell Labs ran in the 1930s while developing  Hi-FI.  An Orchestra sat behind a curtain.  Between the curtain and the orchestra was a physical acoustic filter that had the bandpass of a typical AM radio/speaker of the day.  The filter could be switched in or out.  The audience said the limited bandpass sounded more natural.  This was attributed to people being used to the sound of the radio but not a live orchestra.

Those of us who grew up with the Collins/National/Hammarlund tube gear probably had our standard of how receivers should sound established by those units.  The memory of the sights, smells, and sounds of our youth are with us forever.
