Yes, maybe that’s the only difference. At least it seems professionals also don’t see the need to upgrade nearly anywhere as often as audiophiles do
This (especially unfortunate in the digital world) can mean that their recording or mastering chains stay as they are for 10-30 years (according to what is published here and there, and meanwhile they tend to publish their efforts).
It’s just a guess but when I hear (through the recordings we buy) the positive effects of known upgrades of mastering equipment, I think a little more or frequent „audiophile considerations“ in this world would bring more benefit to what we listen to than most optimizations on playback side.
I wouldn’t have expected the most expensive ADC behind your link to have a golden faceplate in the pro world
And it’s interesting that even the top model has nothing more mentioned than very basic technical data (even very short under “features”) on the manufacturer site. No story about fancy implemenations or further details. Well, it’s a different world (not necessarily worse). Maybe it’s just the difference between the kind of engagement (or call it craziness) for a hobby vs. profession.
But the different worlds maybe also get obvious when observing that e.g. the Pacific Microsonics Model 2 is still considered as the best AD/DA converter within the studio scene and used by today’s best engineers for producing our media we’re listening to on at least 3-5 yearly updated digital playback equipment. The Model 2 as far as I know is 15-20 years old. Even if a digital unit was built like a tank and fitted with gorgeous periphery, a superiority of such an old digital technology (even if it was extremely expensive) to today’s offers would never happen in the playback world That doesn’t mean I doubt how good it is, I have no clue, I just wonder. Imagine…good and expensive consumer equipment of that time was something like a Wadia 861…something we’d guess, today’s alternatives of 1/4th of the price would beat hands down (not to speak of firmware updates for a certain DAC during the last few years )
