Question about late 78s on orthophonic era machines

[Governor Flyball]

Yes, everyone has a different opinion on this for sure. I generally buy European pressings of any late 30s and 40s records I might want to play on an acoustic machine.

The reason later European records sound better on acoustic playback machines is because the Americans more aggressively followed electronic playback technology. Hence the record characteristic on the post 1935 American records with cut bass and boosted treble accomplished a finer groove pitch for longer recordings consistent with quieter playback when played electronically with proper equalization.
