Hi noromance,
Not arguing your opinion, but many (including me) used the early Classe’ class A/B amps via the XLR inputs. Dave Reich designed the DR-9 with single-ended inputs and later succumbed to pressure from Glen Grue to add XLR inputs. Reich did so in a less-than-ideal way, using a cheap opamp in the XLR circuitry. This continued for years in the DR-10, DR-15, and DR-25 and even in the later Fifteen and Twenty Five models after Reich left Classe’. I can personally attest to the lack of dynamics and liveliness of these amps using the XLR inputs. The result was that they were often described as "dark sounding". A different story completely using the single-ended (RCA) inputs IME.
Is it possible that you were also a victim to this in your auditions of the '80s?
Best to you noromance,
Dave
