This question is kind of the Achilles' heel that Schiit (not exclusively but especially) is exploiting. Their approach is pretty simple -- they are saying, in effect,
"We know that you know that a certain amount of care has to go into construction and parts, and that much of the rest of quality depends on the brainpower behind design and testing. And the ability of those involved to listen and care about the results. Beyond that, fancy boxes and marketing techno-blather could just be hiding bad product or lack of care. We get that and we don't do that; we are smart and we care."
Youtube guys like OCD Mikey and Danny at GR research also call attention to the possible divorce between price and quality. It's pretty much a standard go-to for any reviewer, I suppose.
Then there are the quiet giants, such as Mike at Quicksilver or Fritz. Their stuff is nice enough looking and everything else comes back to customer experience. And their price points are never out of control. But their gear is not sufficiently bling-y for someone wanting to say to their friends, "I'm very rich."
