What improvement came first?


I was sitting here thinking, listening to David Gilmour. Be that as it may, What equipment improvements came ahead of others? For example, in order to hear the difference between amps, wouldn’t you need better speakers first to hear the difference? So in my thinking, speakers advanced ahead of amps.  It was only once speakers became good enough, that the more subtle differences could be heard. But is that correct? What improves came before other ones? Did tone arms need to improve ahead of more advanced cartridges? If so, then improvements of one part can totally depend on advancement of another part first. Improvements in equipment are not just incremental within a category but between categories.

Can not agree with you more that room acoustics are first and foremost paramount to great sound. The reason few people talk about its benefits in the industry is they won't be making any monies from it. Majorities of audiophile products manufacturers are all about equipment. What a major blow in their side if people figured out room acoustics are of primary importance. It's less expensive to achieve great sound with room acoustics than with  insanely expensive audio equipment. My take anyway. Merry Christmas everybody!
Its true. Like the other day we were all at Mike Lavigne's. Best room acoustics I have ever heard, by far. For a while there I thought it was his fine system. But then we got a call on speakerphone and dang if that wasn't the finest audio I ever heard. So whatever you do, forget the system. Build a room. Then all you need is a speaker phone. Bose Wave at the most, stick a fork in it, done.

Short and sweet!

Well said and thank you for these words....All audiophiles beginners and sometimes  others need to read these words....

Merry Christmas...

Very well said, but add mechanical embeddings and electrical one to the acoustic.... But i know that you know already that for a long time...

Like i said beginners need to listen to these words....

No speakers can beat their room, and any room well treated and acoustically controlled can and must be the giant shoulders where any speakers can be seated and can really shine the more...

Merry Christmas to you and to all....
Omg, this statement is a joke, right: “Not even. It doesn't matter what you have, a change anywhere is the same. There's no such thing as system matching, synergy, or weak link. Everything is what it is, and will be heard for what it is, regardless.”

Is it Christmas or April fools day? Room and system synergy are the most important things to consider when building a system.Would you team up a warm sounding speaker with a warm sounding amp? Would you team up a 85db speaker with a 5watt SET amp? Would you put a $12k cartridge on a music hall tonearm? If you don’t know what you are doing, then system synergy wouldn’t matter.
Room acoustics can make great sounding gear sound like crap or a mid fi system sound very good. A good sounding room will allow the maximum benefit out of your gear.
