I wonder if the sound from here is true: https://www.youtube.com/watch?v=oF2zQNGUKPc

That's basically the sound quality my good period equipment gives me. Some gear and records will be better, some will be worse.

I seem to recall Mercury records in the early to mid 50s being mastered with very high dynamic range and fidelity, I bet a minty fresh copy of one of their new releases on an early Hi-Fi system configured for 78s would sound pretty close to an LP.

There were companies that produced microgroove 78s for HiFi after most commercial 78 production ended. One was here in Wisconsin in the 60s.
There's a company called rivermont that's making vinyl stereo 78s currently...I've thought about buying one from them.
