There are many brands that have both lofi and hifi offerings. It isn't just a price point, it is a level of performance.
Think about the All-in-One Rack systems that every mass manufacturer had in the 80s, that was Low Fi
Then look at gear in early 90s like B&K, Hafler and a few others. You could get decent sound and level of performance than above. I considered this Entry Level to High End.
Sony had Sony and ES, Onkyo Had Onkyo and Integra (later combined)
Today there is TEAC, which is low end, but also sell Very High End gear under the name of Esoteric
There are way too many variables but if you go out and listen to a bunch of stuff at varying levels of both performance, which sometimes relates to price, you will get a first hand understanding and answer to your question.
And 40 y/o recapped receivers are not High End in my book.
