Earl makes a great point.
Way back in the early 80’s l used to hear Maggie’s regularly on weekends with mainly jazz labels....
Most of these quality labels had a familiar presentation.
But once l got my diy 4343 Biamped clones going we became familiar with right sounding recordings.
52nd Street really snapped with dynamics and clarity on the 4343’s.
I can only assume Jbl monitors were used in the recording process.
In any case we craved for well recorded imported pressings and enjoyed marathon listening sessions that lasted whole weekends.
The benchmark of enjoyment was the next door neighbor knocking on the front door for 15 minutes or so. We only heard the knocking between tracks. The complaint was he could not play his own LPs because the stylus kept skipping across the surface of the record with the bass vibrating through his house! (True story). Never a problem with the Kenwood KD650 turn table equiped with FR 12 arm and FR mc cartridge.
Edit. Our friend with the Maggie’s said at the time the JBL midrange was the best.
