HF stands for High Fidelity, but why?

Wiki source HA Hartley wrote about High Fidelity in his Audio Design Handbook of 1958 where he states:

"I invented the phrase "high fidelity" in 1927 to denote a type of
sound reproduction that might be taken rather seriously by a
music lover"

In his book he also drew reference to High Fidelity and car engineering. The book is lttered with the term High Fidelity.

I suspect that shortly afterwards any electronic music equipment maker worth their salt jumped on the High Fidelity bandwagon (pardon the jolly term) in their marketing and the shorterned version happened within years to modernise.

Lancia could have heard it way back as a thought that described their cars - just didnt surface till early in 1960.
