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


I am in a hi-end audio store today, speaking with the owner, who has been in the audio business for almost 40 yrs. Super nice guy. Can talk up a storm - but as a good thing... where someone like me can learn a thing or two.

He said something that I found curious... audio equipment (pres, amps, rcvrs, speakers) sound better today than just 20 years ago, b/c ’they didn’t have the same technology back then we have today'. Why? Better materials, better components, better r/d... the stuff just sounds better in today’s world, he is telling me.

Coming from someone who doesn’t know any better.... is there any truth to this?

I love vintage technology, especially watches. But the performance gap between watches produced during the "Golden Era" (i.e. '50s and '60s") and today is far more narrow than that of stereo components, cars, or pretty much anything else.

I was using a re-capped and upgraded Accuphase E-303x integrated amp for about three years, and enjoyed it thoroughly. But when I switched to a used Hegel h160, I was very surprised at how big a step forward it was. 

On an inflation adjusted basis, they were comparable in cost, and yet despite the obvious quality of the Accuphase, it was no match for the Hegel.

David rebuilds them in 2021 and his modern  designs are fine too.
Well, yes to materials and technology. No to the sound, good vintage is simply good. Individual choice.
Digital gear today is far and away superior to vintage vinyl, particularly on digital recordings post ca.2000. The same is not true for amps nor speakers, particularly at the high end
When it comes to amps, I would think that the passage of time treated tubes and SS differently.  There haven't really been any new tube circuit designs in decades, though some of Bob Carver's recent work might qualify.  As someone pointed out, if you were to update older tube gear, replacing aged components with new, where would the vintage gear fall short?  

SS may be a different story, with newer topologies.  That said, an awful lot of experimentation was done in the 70s and 80s.

Speakers have seen the greatest change, benefiting from discoveries and advancements in material science and manufacturing, as well as design and testing tools.

Pretty much everything I own is early 90s or older, except for the home theater preamp and amp, and a pair of speakers from 2008.  Most of it has been recapped and restored, tube and solid state.  Would love to try some new gear once I get my listening room set up.  Thinking Lyngdorf with RoomPerfect might be my first foray.
