Me after a few beers in a dark room, listening to Pink Floyd.
So it is not just the looks, it functions in a peculiar manner.
I think you’ve just summed up why I like the operation of the unit when i listen late at night - there is a visible feedback that means I can apply volume control, crossfeed and eq all with the touch of a button without having to lift the unit to view a screen. I’d say it’s a well designed interface/ui that succeeds for being so different (and friendly?) in use whilst maintaining complete functionality, and I like the industrial design.
After a few hrs the first night where I familiarised myself with the online manual and button operation/colour sequence I can say I’ve not looked at it again.
