I took part in that original discussion, and I was one of those who wrote "the Golden Age of Audio" is right now.
The reasons are many, but one which stands out above all others is the internet. Not for downloading or whatever, rather, back in anytime before the internet, one had ONLY the local dealer for equipment. And used? Hah! if your local dealer did not have it, you did not ever get it.
Now, ANYTHING ever made can be had, from anywhere in the World, via the internet.
Also information. Used to be one only had what a few magazines told you. Audio, Stereo Review, High Fidelity, Grammaphone, and later on The Absolute Sound, Stereophile.
If it was not in one of those, you never heard about it, unless your local dealer carried it, and then you had to take the dealers word it was the best or whatever.
The magazines had a make or break lock on equipment. A bad review could destroy a company, or, make it a great success.
No anymore. Now, with dozens of ways to read up on any bit of equipment, that stranglehold is gone.
Buying music? Never better than now. Internet anything is available.
Used to be only big cities had stores with huge selections..
I can buy an item direct from England, Germany.. Japan. no problem. Not in the past. Only a few items were imported, and they were very expensive.
So no question, hands down, right NOW is the best time ever for audiophiles.
So for these reasons, besides the better equipment than ever before, NOW is the Golden Age.
Folks who dwell over golden memories of past ages are more fantasizing about their youth, than the actual times.
