The random plate colors will indeed continue, as that is actually part of how the price is kept low (I take the odd bits and pieces that would otherwise be scrap).
With the new Quickie, it's much easier to look at the kit and know that the power is on or off. For mine, I have the volume knob pointing up for no volume, and the power/input switch pointing up for no power. I can see them across the room and know that both need to be pointing up to be off.
As an added bonus, a Goldpoint selector switch will now integrate nicely into this kit.
The sonic impacts of the changes are noticeable, but not night and day (like the PJCCS). It's difficult to say which one made the greatest impact, as they were all done at once.
