Hi end audio equip sounds better today than in decades past due to tech - T/F

No, 20 years ago, 2001. (between 01-21)
Yes 40 years ago, 1981.  (between 81-01)
No 60 years ago, 1961 . (before 1961)

I had to think on that.  I really think from the 80s to 2000 things were pretty heavy, ran extremely hot, were HUGE, prone to a lot of electrolytic leaks and failures. They started using LEDs, small planars were being developed. A LOT stronger, lighter, and UN affordable composite were developed (now they are affordable).

Pre 61, LOL The last of the On/Off volume controls. Remember You turned on the unit and that was the volume control too. They still use them today in a pro tube amps. All together different. Valves.
SS was truly JUNK. Transistor radios, what piles of heaping trash..
A TV, you could barely move in a room without it going wiggy.
Radio was a lot more popular when I was a kid.. TV was on the weekends for a couple hours.. Bonanza, and Lawrence Welk. :-)

Nope! The "good stuff" of the past can still hold its own with any of today's touted offerings by the "golden ears" crowd! The idea of continual forward progress in HiFi is an illusion benefiting magazine advertising revenue!

Case in point: my vintage 1973 Altec Stonehenge I's  vs. the Tekton DI's! How about some Zeppelin and Ten Years After as playback  choices? Maybe some Pink Floyd and Hendrix, too! Both speakers look like contenders that can "rock out"!

A nicely restored pair of Marantz Model 9 mono tube amps can today still compete with any four and five figure tube amps!

Add those same Marantz 9's to a pair of KLH Nine full-range ESL's and you have a killer combination circa 1962!
