Seems to me PMB you are just attempting to shut down the discussion.
I suppose I should have been more specific. This is not the first time you've suggested that crossover component upgrades can be a magical fix. There is absolutely no real evidence that switching out crossover components with more expensive ones of the same value make a difference to the human ear -- you know, those things on your head you like to trust?
Now, if your suggestion is that they try different crossover points, that's a valid request. But again, they've already done this or are already doing this across their line.
