Just a few thoughts I can’t help but share…
The incredible quality of the USB input of the MK II, as good as I2S if not better, could have caused a drastically change in PS Audio plans on a product like the AirLens?
Is still a fundamental need for MK II owners (Bridge II users a part)?
What is the most urgent problem to help more MK I owners to replace the old DAC for the new one, if the AirLens is no more available?
Is the Bridge Box a temporary solution or the first step into a different direction?
Is shortage the only reason why the AirLens has been suspended or is a contributing cause?
Life can always change, I respect the possibility to go for another way when circumstances make this inevitable and I suppose @Paul is facing this new situation with his proverbial calm and experience.
Take your time Paul, I’m sure your final choice will be the best choice, AirLens or not AirLens here a customer who knows that patience is a virtue!
