> 78's which had plenty of space between the grooves since there was only one tune per side.
Hence the appearance of the 12" 45 rpm disco single in the 1970's, which sounded a heluva lot better than the 45, especially in the base.
It was even better to score the "promotional copies" which had no bubbles in the plastic or other flaws. I don't know if the PCs were pressed on a separate line or were just hand -picked from the normal production run, but they sure sounded good.
The most high-fidelity record I know of is the direct-to-disc recording of Carlos Santana and Paco de Lucia in acoustic duets.
Unlike the others in the direct-to-disc series, there was supposedly no console between the artists and the input to the master record-cutting stylus, and no remixing after recording.
The difference was quite apparent, and I have always been convinced that the fewer electronic components between the artist and the listener would yield the best reproduction.
I've never even heard a simply amplified PA system sound as good as the acoustic instrument the mike is attached to. This is with high end pro equipment, not home audio stuff.
