Recordings were crystal clear. Folks sat around and listened together. Music was awesome.
Small market recordings beg to differ on being crystal clear. I have some 50s and 60s jazz and blues recordings from local New Orleans labels and the SQ is OK and few are just bad when it comes to clarity of recording.
Maybe if you focu only on big label recordings and certain 1st/2nd pressings would the statement that records from the 50s and 60s were crystal clear be true. And only if you were listening to that vinyl on a high-end system from that time. The majority of people were listening to music on console systems and cheap set-ups, not high-end or DIY setups.
