That's a pretty generalized comment if you're saying that low to moderately priced gear has no bearing on the quality, functionality or longevity of the item being purchased.
"You get what you pay for" isn't some bullsh*t cliche'
It absolutely is in the world of manufatured products.
You may pay for a reputation, a brand, a method of production, advertisement, good looks, decency of worker wages.
The retail price of a manufactured product barely depends on the product itself. It's a social and commercial construction.
One of the most often quoted illustration of this concept is that Fender and resellers get a better marge on a Squier than on a MIA instrument.
A widely distributed product saves so much because of wide scale production that it can often offer way better specs and quality than boutique products of the same kind, yet the feeling of buying something unique make people rate a rarer product higher.
In the case of Zoom (and others), the quality of ADA converters they use is equivalent or higher than the vast majority of recording and monitoring devices used by common musicians for their cherished analog gear, yet the price makes them consider the quality as inferior.
We listen not only with our ears but also with our wallets, eyes and brains.
If Zoom decided to use gold plated jacks, switches with a louder clank, industrial looks and double their price, they'd get a completely different appreciation.
This kind of decision is taken by commercial, not engineering services.
