Yep...those Telarc Soundstream recordings are great....and the LP pressings from the late 70s have 96dB dynamic range. When they came out people literally destroyed loudspeakers with them.
The other really famous Telarc disc was the Frederick Fennell Cleveland Symphonic Winds record with it's bass drum that required a note inside the sleeve advising users could damage their speakers unless they kept the volume low.
And no....the stylus does not jump out of the groove, nor does the record seem to be damaged with repeated plays...urban myth. I can put on my original copy of the Frederick Fennel disc, now well over 40 years old, and hear that bass drum perfectly.
The thing with the Soundstream system is that it's minimum 50kHz sampling rate an 16 or 20 bit.....with a computer DAW as part of the system....recording engineers, producers and mastering engineers were expected to examine the soun waves on the screen and check for any aliasing or digital artefacts....and correct them manually. It worked, and the extended frequency response over and above 44/16 systems seems to really make a difference...compare to the early Denon "Direct Digital" LPs from the same era which sound truly horrible. The Telarc people also knew how to record an orchestra. You don't mic up every damned instrument individually.
