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.

@wesselc The first use of balanced XLR’s in Accuphase appear to be from the P-600 amp in April 1983. At least that’s what I find on their webpage. It’s under about/company profile/ and click on the pdf file at the left hand side that says the beginnings of accuphase and click on the blue highlighted link about their 240 models have been introduced and find this model and year. They even have a picture of it and an explanation. Their P-400 in 1979 also appears to have XLR connecters but not sure they are balanced and its hard to see with the picture.

@atmasphere Good question! I apologize I don't know. I'm not familiar with early Accuphase. I was just pointing this out. Did Accuphase ever produce professional equipment? I know their founders worked for Kenwood and changed the name of their company more than once.

@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
