For what reason you wish for new products / new design ?
Whats missing from your perspective ?
You only show pictures but are very unspecific what you currently do not like.
BTW ...
Are you aware off, that in one of the last firmware updates RME introduced the AutoDarkMode ?!
On the Pro at least the display will be turned off.
On the DAC it turns off Display and all LEDs.
In terms of the big heatsink, that you glued on top of your ADI-2 Pro.
It has been stated a couple of times by RME in the forum that the case is designed to transport heat well to the outside.
There should be no demand to add an additional heatsink.
Or is your surrounding environment already so hot (living under a roof) ?
