Hi Sebatron, As a user and designer of audio equipment, one thing I always spend a lot of time wondering over is the control surface and "user-friendliness" of equipment. What are your thoughts on the user interface of equipment? For example, it's not just the physical layout of controls, but where they are "placed" electronically. When an EQ frequency or level control is to be used, there can be different ranges of "spread". Sometimes with EQ you only want an incremental adjustment, whereas other times you want to do a bit more "damage". So where, as a designer, do you place the goalposts? Is it best to have a device crammed full with possibilities with switchable gain-ranges, yet which is difficult to use to dial-in a basic setting; or a minimal "less-is-more" approach which is foolproof? With some equipment I've bought, I've felt that the designer(s) have not been generous enough with the "controlability", so I've opened them up and expanded the ranges of pots etc and added switchable values. I suppose it's the "one louder" question really in a different guise ...but it's definitely an issue when prototyping your own designs, and assessing a prospective purchase!
