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?

The high point of maturation for my ears was the 2C3D system heard in the late 90s at Progressive Audio in Columbus OH. First time I can remember hearing life size vocal height and separation around audience members as they were clapping. It was as impressive with Thiel as it was with Avalon, and that system is still help as a bench mark for mine and others I design today.
The true Audiophile system of the mid to late 1950's surpasses in quality of audio reproduction the "state-of-the art" digital system in use today. Tube amplifiers, based on the Williamson stereo design, and others, together with reel-to-reel tape decks were the standard for recording and playback. Modernly, recording engineers try to imitate the 1950's recordings using digital equipment. Unfortunately, without much success. Audiophiles in the 1950's - 1960's had many choices of speakers, tube amplifiers, preamplifiers, turntables, all made specifically for the Audiophile market. Most of that equipment is scarce and expensive today. As a matter of economics, the audio and music industries require periodic renewal to survive. That means "new state-of-the-art" products to sell to a new generation. Perhaps the "new generation" doesn't require audio perfection with the forms of music popular today. Who can hear the difference in the dynamics of a recording played at 108dB??. All of the new forms of media lack the dynamics of well recorded 1950's performances. Hi-Fi sound never "got close to where it is now", it far surpassed where we are now 50 years ago and everything since has tried to replicate the peak once reached.
Buff sells Thiel products and it should have been disclosed in his post.

Repeat offender.
Commcat,

While I disagree with you that there was no real progress up to the mid 80's - culminating in digital audio (I actually think there was progress).

I tend to agree with you that music was probably better sounding (on average) in the 50's than the monstrous squashed pop music we get today on boomboxes...however music is widely available and cheap for the masses now so I guess that is a form of improvement (if you can call it that).
