I’m not sure we can blame it solely on MQA since qudelix did switch chips since they could no longer source the ES9218.
Recently, ESS discontinued ES9218, and now, we’re no longer able to source the part.
Consequently, we will use ES9219, pin-to-pin compatible with ES9218, from the next production lot.
Both ES9218 and ES9219 are technically the same in terms of output power and power consumption.
It means just a single part replacement, not a model change.
We’re going to release the Qudelix Chrome Extension app for Windows/macOS.
The Chrome Extension app works with Qudelix-5K over PC USB.
I’ve been seriously impressed with the amount of features they’ve added since the 5K launched last year.
