When did the Hi-Fi sound mature?


Just a random thought I always had: when did the hifi sound got close to the point where it is now? Given the system from end to end. I don't mean comparable to state of the art today, but comparable to say an average audiogon system. The 50's? 60's? 70's?

Al,

Nice post. It is always pleasant to see a balanced view that does not follow the heavily beaten path of simply pitting digital against analog or tubes against SS!
Yes, that's right. I believe that John Curl designed all of the JC-designated products for both MLAS and, in recent years, for Parasound.
