Should I remind you that there are plenty of old planar iems priced at 1k+ usd? (AAW Nightingale, lcd i3/i4)
Even amongst the new planar iems, you've the campfire audio supermoon priced at 1.5k usd.
If the s15 is an upgrade, and it is, most likely, the price is still pretty good considering r&d etc.
Letshuoer themselves have iems that are priced way higher, the cost shouldn't surprise you.
letshuoer isn't pushing planar iems into unaffordable price ranges, if anything, they were one of the companies that brought it to the affordable price range, plus, the S12 is still available for purchase, it's on you if you want to upgrade to the latest version (Iphones are a great example)
"Letshuoer are doing nothing for the true HiFi community and Head-fi community. A real kick in the HiFi"
What are you talking about, they're a company selling products, they own nothing for the Head fi community or "true Hifi community" whatever that means.
"My faith in Letshuoer has totally gone."
Why now, why not when they released their cadenza iems? Have you seen the price on that pair?
