Can anyone tell me when XLR connections were first used on stereo equipment. (what years)?


I know RCA connections can produce incredible sounding music, too, but in my experience, I've always found XLR connections sound more detailed to my ears. I'm interested in a vintage integrated amp. Perhaps that's an oxymoron. Anyway, please let me know units/brands that you know about.

@willywonka The reason I asked is amps and preamps for pro audio/recording studio use have had XLR inputs going back to the 1950s. So the distinction is really the ask of this thread. 

Its either Atmasphere or Burmester, as @terraplane8bob  already said-

Burmester 838 and Burmester 877 and 878 (from 1983. and 1987 and 1988)

Also, there are Burmester amps model 850 from 1985

@atmasphere thanks for adding the extra info. 

I have a lot of studio gear. Some uses pin 3 as hot, some pin 2 as hot and some have user selectable hot pin out such as the MTR-15.
