I think one of the biggest downers for many HR is the sound they want is from some famous album thats been mixed and mastered.
So they get the big dollar item and it doesnt sound much better than a $500 used Grace Design, which doesnt sound much different than a $100 Rane MS1..... that even the famed Steely Dan engineer used on big albums of that era. My experience. My ears are fine, the huge pro sound just wasnt there for the money. For HR where there isnt a large amount of work and paid by the hour session musicians and engineers...a unit breaking down = quality issue, has a limit to ROI.
One of the largest albums of all time per BIllboard is the Adele...and the engineer used the Rode Classic II into a UA 6176...but into the rabbit hole of reading, that simple combo made it to the album, but it also went through massive plugins at mixing and and the Mastering of all of it went through more polish. So to buy a Rode Classic II and a 6176 probably wont sound the same as her finished sound on the album.
My experience with the expensive preamps was complex, sound wise I didnt hear some huge polished album sound, but the build and designs of the internal guts is cool...like a LA610 or a ISA One, theres alot going on inside those compared to a Rane MS1. The caps and all the science of parts is amazing.
The history and stories of the old gear of yesteryear is for older folk too, imo.
My sons kids wont even really know much of the Beatles let alone Elvis and before him Frank and Bing who were the Beatles of their era.
Then through the 1970's to 80's to 90's to 2000's...whose gear are we copying and cloning and which albums made the gear popular?
Will the Billie Eilish crowd be impressed with a REDD 47?
the REAL NEVE...or one of the Clones.... does it end?
Dallas Heritage Auction sells posters of old movies for $190,000...something for rich to spend their money on or investment mentality. Neither for me fortune-lessly...
As for Engineering, it comes down to sound. Forget the name brand, get to the sound. Forget the price tag, forget if its a Tube, Transistor or IC....does it sound good? Ive heard many expensive pieces with subpar musicians and the gear doesnt save them, its only something to talk about at the bar.
Tubes , Transistors, IC's.... Capital Records golden era and Tony Bennet, Beach Boys.. ... or Bedroom Produced Billie Eilish ITB..and AT2020 and interface preamps...
It all starts with a Mic and Preamp one way or another.
Vintage King puts the Neumann U47 tube and NEVE 1073 and Emu-comp as their "top" vocal chain in an article.
Even that expensive setup will get Mix Plugins and Mastering polished before going to the radio...or streaming site.
then theres always the well done SOS shootout that blindfolded the experts chose the ART MPA and overall it came in side to side with the NEVE and other high end preamps.
makes the brain hurt...lol
