Well, I wrote NDSP support... and now, we wait. If they want hundreds for a repair, I'm going to be in an awkward situation where I either cough it up or feed a landfill. And the latter option with a device this valuable would be madness. So I don't have a lot of leverage here.

This is exactly how I felt with the HX Stomp a few weeks ago, except the stakes weren't so high.
More importantly, I'd already decided to move the Stomp, whereas the QCs are the platform I really want to be using. There's nothing to replace them that'll make me as happy. But if I get burned on this repair it's going to be that much harder to trust them going forward.
