This thread always seems to bring out the best in people, just like so many other threads. I just laugh after so many years in this hobby and seeing this with all brands.
Cayin has a 5K Anniversary DAP and have had a poor launch with some units having issues. Folks trying to find cables and IEMs that don't hiss to adapt to their purchase, rather than worrying that the DAP shouldn't do that. After shelling out 5K the folks making excuses for the unit and validating their purchase, it's human nature.
That said, Cayin jumped on it admitted the hiss and is trying to make it right. I see the same here, Jack said what is happening and has offered to make it right.
Also, if a manufacturer tells you how to properly handle or care for their item, it may be good to listen. If you want to do something else because you know more than those that made the item there are consequences. Wiggling or pinching, it appears wiggling is the preferred method.
Throw shade at who you want, or a product, it is an individuals prerogative to love a product or company(Apple vs. Android) It is also someone's choice if they want to make a purchase. The situation here or with Cayin would be different if there was a scandalous coverup, lol.
Watch it unfold and make a decision, purchase or not. I know I want to experience Raven, if I have a negative experience with the build I know it will be taken care of.
