Y'all need to remember absolute vs relative.
$2k is damn expensive. $2k compared to $4k is not. Think of it like cars. If you're looking at a $100,000 sports car, a Dodge Hellcat for $70k is pretty cheap, despite still costing twice as much as what tons of people make in a whole year.
People need to stop acting like flagships are anything but exotic boutique products. For every Susvara and Utopia there are a billion cheaper alternatives. No one is obligated to buy them, nor are consumers entitled to be able to afford the most expensive thing a company has to offer. It's not like lower cost products are vanishing.
The only people who complain about the upward creeping of flagships, in the face of all the Monoprices and Massdrops offering products for cheaper than ever, are people who feel hell-bent on always having "the best" but now it's harder and harder to afford "the best" because they're costing insane amounts.
Just because HFM or Audeze charge an arm and a leg on their TOTL products doesn't mean any of the stuff down the line is gone. You are more than welcome to buy that instead. The tippy top products exist for a small subset of the consumer base. That's why you can't find an LCD-4 in a store. They're made on demand. The Utopia didn't make the Elear go away.
I may never even get this because holy **** $4000 is a lot of money, but its existence isn't a detriment to what costs less. These products aren't causing lower-cost models to vanish. Audeze has ALWAYS made boutique products. The LCD-2 was, what, $1500 or so when it first came out? Now they have the $400 Sine and the two iSine models that are closer to consumer prices. HiFiMan still makes everything down to the HE-400 and paired up with Massdrop for even cheaper items.
I could understand the complaint if this was happening at the expense of affordable products, but it's not. These are happening in addition to. Audeze didn't replace the 2 or 3 with the 4, the 4 happened alongside the 2 and 3. This stuff is bonus. It's companies making crazy stuff for people who have the money to burn. Relax.
